Myopia is 3 degrees - this is a severe disease of the organ of vision and the apparatus of the eye, which occurs under the influence of environmental factors or due to hereditary predisposition. At myopia of 3 degrees, vision correction is required using ophthalmic lenses or surgery.
Myopia is a widespread disease, both among the adult and the children's population of the planet. The steady increase in morbidity is associated with the widespread introduction of technologies, gadgets and electronic devices. W. healthy man The projection of the object of the environment occurs by refraction through the lens of parallel rays, reflected from the surface of the object. After refraction, the rays are connected in the retina of the eye, the nervous impulse creates the projection of the object in the occipital fractions of the brain.
When violating vision by type of myopia, there is a breakdown of parallel rays, after refraction, they are projected before the retina. This can develop as a result of a change in the form eyeball Due to the relaxation of muscles of accommodation or be the first symptom chronic disease. Among the main causes of myopia are distinguished:
The congenital form of myopia is relatively rare, as a result of the vices of the eye apparatus with impaired formation of optical elements and anatomical structures leading to discornation. When involving a sclera in the process, ophthalmologist doctors are diagnosed with a high degree progressive myopia. The weakening of the muscles of accommodation leads to a violation of the fixation of the projection of the external object, deformation of the eyeball, which leads to a gradual decrease in visual acuity.
Often the congenital shape of myopia is confused with anatomical anomalies of the structure of the Elektrica in children early ageWhen the sizes of the opening for the eyeball is less than its diameter. In this case, the Eye Apple acquires an elongated form, but as the kostomuscular skeleton of the child and the orphanage increases, restores and the vision becomes clarity.
Myopia of 3 degree develops as a result of hereditary predisposition, various diseases organ of vision or factors of external aggression. The difference between genetic heredity is to reduce visual acuity to a certain level, not lower than the diopters of the parents. This gives a favorable pregnancy prognosis, visual acuity is not violated in the process of natural labor. The hereditary form of the disease rarely takes a progressive nature, succumbes laser correction vision without the development of complications in postoperative period.

Diagnosis is not a sentence - myopia (myopia) (Zarina Khalikova)
Diseases leading to violation of visual acuity are associated with a decrease in the light-paint abilities of transparent shells of the eye and lens. Such states develop as a result of inflammation of the cornea (keratitis), the mucous membrane of the eye (conjunctivitis) or closet of lens (cataract). Proliferative-degenerative changes in the gloil shell are associated with the violation of the synthesis of collagen and protein connective tissue, leading to her cloudy, loss of elasticity and deformation of the eyeball.
The effects of the factors of external aggression leads to a violation of the balance between the voltage of accommodation muscles and the convergence (focusing on the object). This causes an accommodation primary spasm, a decrease in visual acuity, which over time is transformed into the progressive shape of myopia.
Spasm is developing when reading in a twilight, long-term use of the phone, without complying with the display brightness mode with a high duration of the computer. The progression of myopia is a high degree leads to the appearance of severe complications.
Treatment of myopia is highly carried out using ophthalmological lenses, glasses or surgical treatment methods. After diagnosing the disease according to the classification of the ICD, the doctor prescribes the patient with glasses or lenses with certain diopters for constant wearing.
If the patient has a concomitant disease, such as astigmatism, a special type of lenses is applied, aimed at the correction of both states. With astigmatism, in most practical cases, wearing glasses are assigned, this is due to limiting the use of lenses against the background of the presence of two pathologies.
If the patient has a higher degree of myopia, but without complicated states, at the first time the oculist prescribes wearing glasses to adapt the eye muscles and removing the accommodation spasm. The glasses are convenient for the first experience of restoring visual acuity, when working with abstracts, coursework and other paper work, requiring special care. Unlike lenses, glasses can be removed during the occurrence of fatigue, perform physical education for eyecutters.
Improving visual acuity Against the background of wearing points during the first year, is associated with the elimination of the accommodation spasm, which indicates the right direction of treatment. Complicated forms of myopia in this case are developing extremely rare. The risk of retinal detachment develops with a decrease in visual acuity of more than 9 diopters, the presence of risk factors, such as:
In the development of complications, the patient is assigned to the degree of disability, regular treatment and control over the progression of loss of vision is required. With a decrease in vision, more than 6 male face diopters are not suitable for the service in the army due to restriction of physical exertion, which is due to the myopia of a high degree.
Ophthalmic lenses are convenient for use in everyday life, active lifestyle and sports. This is explained by the high comfort of wearing, the lack of external changes in the patient and complete imperceptibility throughout the day. For the first time to select the lenses should the attending physician for accurate correction of vision, the selection of the necessary parameters.
With myopia, more than 9 diopters for high-quality recovery of visual acuity are used by special lenses that are manufactured under the order. This is due to the thickening of the lens, using high-quality materials that do not irritate the mucous membrane of the eye.
When wearing lenses, it takes to take breaks one or twice a week, replace on glasses, which warns the development of dry eye syndrome. The use of moisturizing drops increases the comfort of the eyes, restores the operation of the tear glands and moisturizing the conjunctiva. The refraction of parallel rays on the retina when wearing lenses is more intensively, which explains the use of smaller diopters due to the proximity of the lens to the lens, in contrast to the glasses. Independently buying lenses is recommended after several months of use, complete learning to the dressing process and shooting.
Under myopia, a high degree can be used colored lenses that change the color of the iris. Colored lenses with diopters are sold in Internet pharmacies or manufactured to order. To reduce the risk of inflammatory diseases, changing lenses is required according to the service life, observing the hygiene mode.
This contributes to the qualitative purification of the lens surface from the proteins and the selection of the eyes, prevents the reproduction of pathogenic bacteria. To reduce the risk of irritation of the mucous membrane, the lens thickness is selected individually taking into account the personal preferences of the patient.
Surgical methods of recovery of vision are widely used in ophthalmological practice Thanks to the security of I. high efficiency. With a highly high degree of laser correction allows you to fully restore visual sharpness, forget about glasses and lenses. The most popular microsurgical technique of Lasik, at which the integrity of the cornea is preserved, due to the restoration of the outer layer. Full healing of the cornea reduces the risk of injury to the iris, hitting bacteria and viruses inside the eye.
After laser correction operations, patients need to carefully monitor the state of the eyes, avoid rubbing with their hands, ingress of foreign objects. Installing special antibacterial drops in the postoperative period reduces the risk of inflammation of the shells of the eye, improves the healing of tissues.
Restriction of physical exertion during the first three months will warn the increase in intraocular pressure, which negatively affect the restoration of the integrity of the cornea. On the recommendation of the attending physician in the period after the operation, a course of physiotheredur or instillations of attending substances contributing to the speedy recovery is assigned.
Surgical treatment of disruption of transparency of the lens (cataracts) uses the classic method of facoemulsification, which is aimed at creating holes in the cornea. The restoration of parallel rays is restored, which affects their refraction on the retina of the eye.
The destruction of the affected lens and its painless removal occurs, after which an artificial implant is installed. The operation is satisfactorily transferred by patients regardless of age, has a short recovery period.
The progressive myopia is a high degree during pregnancy is a contraindication to natural childbirth in the presence of risk factors for the development of complicated forms of the disease. A pregnant woman can give birth herself in hereditary myopia with acute view of not lower than 6.5 diopters and in the absence of complications. Complications include the dystrophic retinal detachment of the eye or degenerative-dystrophic changes in the retina, which are a threat to the beginning of its detachment.
In the presence of contraindications to natural clauses, the future mother is assigned a planned caesarean section. Pregnant women pass planned surveys by an ophthalmologist for a period of 11-14 weeks to determine the visual acuity and the beginning of preventive or therapeutic measures if the correction is necessary.
If the work of a pregnant woman is associated with a long reading, during the preparation for childbirth, it is especially necessary to pay attention to the exercises for the muscles of accommodation aimed at relaxing and increasing focusing. Exercises are performed several times a day, are not contraindicated during pregnancy and myopia of high degrees.
In the early periods of pregnant women with congenital or acquired myopia according to the testimony of the oculist doctor and the lack of contraindications, laser correction is carried out. Such an approach is an innovative in modern ophthalmology, a few years ago, such an operation was an indication of Cesarean section due to the high risk of development. postoperative complications in the process of natural childbirth.
This is due to the latest methods of laser treatment, gentleering the impact on the cornea of \u200b\u200bthe eye. Exercises for the restoration of vision and the recruitment of the accommodation spasm are aimed at alternating loads and relaxation. The focus point is moved to the closely located object and the point in Dali. Exercises are carried out through every hour of work at a computer or with documents for 15-20 minutes.
Ophthalmologist prescribes the use of droplets, relaxing eye muscles, in early pregnancy in the occurrence of voltage headaches. Drops are safe for pregnant women, there are relaxing effect, restore vision and prevent the progression of myopia.
Myopia is headed by a list of common refraction anomalies. The disease is characterized bad vision distance. Myopia is a high degree - a heavy variant of the course of the disease, accompanied by very low visual functions of both eyes and the development of complications. This nosological unit includes various origins and clinical flow Pathologies, which unite the refractive strength of the optical apparatus from 6 diopters and above.
Types of disease in the severity of the flow are presented in the table:
D (diopterry) is a unit in which the refractive force of optical media is measured.
Highlight three clinical options Myopia, more about them in the table:
A type Characteristic Hereditary Genetically deterministic disease, inheritance per dominant or recessive path Differs fast progressive loss of visual functions Congenital There is still in the womb of the mother due to the effect on the fruit of infections or toxins Violates the development of the eye gland embryo Myopia is manifested as a result of damage to the anatomical structures and is accompanied by other pathologies (keratoconus, lenticultural) Acquired Due to excessive height of the eye on the head-rear meridian at an early age
With such pathology, the bodies of vision become more elongated.The high degree of myopia and its species differ on the roots, but they lead to the elongation of the visual apparatus. Normally, when the length of the eye is not more than 25 mm, rays emanating from the subject, passing all optical media, focus directly on the retina. With a long eyeball, the image is projected before the mesh shell due to too much degree of refraction. Because of this, the patient sees the patient badly. At close range, the rays go at an angle and, with the help of the accommodation mechanism, their focus is right on the retina. Thanks to this, people with such a disease are clearly seen near. In pathology above 6 diopters, visual functions deteriorate so much that a person distinguishes only objects that are in the face.
Symptomatics
Myopia is highly characterized by progressive deterioration of visual functions for long distances. The development of the disease may be rapid, in such cases the deterioration comes to the diopter per year. This option is considered malignant in terms of forecast. In addition to the main feature, patients are concerned:
- pain in the head;
- photosensitivity;
- tear;
- fast fatigue eye;
- floating clouding.
An overvoltage of the eye leads to the accommodation spampity.Do not confuse true myopia and false. The false or spasm of accommodation occurs due to the constant overvoltage of the crustal apparatus. Such a hypertonus leads to the absence of relaxation of ciliary muscles. This disease occurs due to the violation of the mode and overvoltage of the eyes.
Drops are used to treat false myopias, and its true variant is an anatomical pathology, in which such therapy is unsuccessful.
Diagnostic methods
During the diagnosis of complexity, do not arise. Use the following survey algorithm:
- Visiometrium. Determination of visual acuity and selection of speaking correction using Sivzian tables.
- Refractometry or skisopia. To determine the true strength of refraction of rays with optical media. It is carried out on a wide pupil.
- Determination of the size of the PZO (front-length segment). In adults, it should not exceed 25 mm. Age norms vary.
- Ophthalmoscopy. Study of the eye dna, on which specific dystrophic changes in the mesh shell are possible. They are important in the myopia of severe degree.
- Ultrasound (scan mode). Visualization of the anatomical structures of the visual apparatus to determine complications from the retinal.
Treatment of disease
Conservative methods
With such a degree of illness, it is more convenient to wear lenses.Congenital myopia is high, as well as acquired, conservative treatment is not subject to. The only method of improving the quality of the patient's life without surgery is the selection of proper optical correction. Taking into account the fact that with an increase in the refractiveness of the lenses thicken, myopia 3 degrees in the patient dictates the need to make glasses from materials (mineral glass, polymers) with a suitable refractive index that differ in large specific weight. For the same reason, many patients choose the wearing lenses. Selection of glasses in such cases is a challenge and does not guarantee 100% of vision. Patients with high myopia is recommended to be treated in hospital once a year. Inpatient conditions for therapy use injections with vitamin complexesthat improve the nutrition of the retina.
Thank you
The site provides reference information solely to familiarize yourself. Diagnosis and treatment of diseases must be under the supervision of a specialist. All drugs have contraindications. Consultation of a specialist is obligatory!
It should be immediately noted that at the present stage of the development of medicine, it is possible to restore normal vision to even patients with a high degree of myopia, but only with timely start of treatment, have not yet developed complications from retina and other intraocular structures.
For correction and treatment of myopia, you can use:
Selection of glasses in myopia is carried out during the study of visual acuity. The patient sits before a special table with letters of various sizes, and he put on a rim with removable lenses. The doctor then begins to place the lenses with a certain scattering force in the eyes of the patient's eye, and at first weak, and then more strong. For the manufacture of glasses should be used minimum ( by force) a scattering lens that provides optimal visual acuity ( 0.9 - 1.0, that is, almost 100%). In this case, the patient should easily read the letters in 10 row of the table used to determine visual acuity.
It is important to note that the testimony of glasses depends on the degree of myopia. So, for example, in myopia of a weak degree ( up to 3 diopters) Points should be used only when viewed by far objects ( for example, they can enjoy drivers while driving). During reading, working at a computer or viewing TV shows should be removed, since otherwise it will aggravate the severity of myopia and will lead to its progression.
In myopia, medium-sized glasses can be used while working with objects located at a closer distance ( for example, being on lectures in the audience). At the same time, such patients are usually not needed. In this case, bifocal glasses may become an ideal solution, in the lenses of which two dissipation hemispheres are installed ( one above and the other below), and the lower hemisphere must be 2 - 3 diopters weaker than the top. In this case, if necessary, watch the patient looks through the upper part of the lens, and when working with objects at a closer distance - through the bottom. This makes it possible to prevent the progression of myopia, which can be observed during the constant use of excessively strong lenses.
Also, the lenses are recommended to be used with anisometropy - a pathological condition, in which the refractive force of the right and left eye differs. Anisometropy of up to 3 diopters can be tried to correlate with conventional glasses ( at the same time, the refractive force of each lens must correspond to the refractive strength of the eye, opposite which it will be installed). With anisometropy more than 3 diopters, preference should be given to contact lenses.
The selection of contact lenses is made according to the same rules as the selection of glasses. It is worth noting that with a high degree of myopia, the full correction is not recommended immediately ( especially in children and adolescents) Since the accommodative function of the patient's eye can be simply underdeveloped. In this case, the complete correction of myopia ( that is the purpose of the points that read the patient letters from 10 rows of a special table) Slow down the further development of accommodation, thereby reducing the likelihood of reducing the degree of myopia in the process of growth and adults. That is why when first prescribing points it is recommended to correlate myopia by only 80 - 90%, and in the future ( in the absence of positive dynamics) Increase the strength of the lenses used until the optimal result is achieved.
In the process of preparing for the implementation of the procedure, a thorough examination of a patient is carried out, comprising computer keratotopography and other high-precision research methods. The resulting corneal status data, lens and eyeballs are recorded in a computer that calculates optimal parameters for laser correction. The procedure itself is also controlled by computer programs, and therefore the risk of a random error comes down to a minimum.
The procedure of laser correction of myopia is performed within a few minutes. Initially, the patient enters a specially equipped room and falls on the table over which the laser apparatus is installed. He in the eyes burst a lot of local anesthetic, which temporarily block all kinds of sensitivity. This is necessary, in order for the patient during the fulfillment of the procedure, the patient does not react and responded to the actions of the doctor. Also in the eyes dig drugs that expand the pupil, which is necessary for the accuracy of the manipulation performed.
After the anesthetic acts, the patient is asked to fix the head in a strictly vertical position and do not move it. To prevent random blinks during laser operation, the eyelids of the patient are fixed using special locks ( the procedure is painless, however, it may seem unpleasant). The doctor then checks the position of the patient's head once again, sets the laser apparatus directly above the operated eye and asks the patient to lock the look at the flashing red tube of the device.
When all preparations are made, proceed directly to the correction. The first thing on the corneal surface is made a shallow circular incision, after which the upper layer rises in the form of a flap. After that, the laser is immediately entering. According to a predetermined program, it produces a removal ( evaporation) A small layer of cornea fabric, reducing its curvature. This stage of the procedure may last a few seconds or minutes. After the end of the correction, the separated flap returns to the place. The patient should stay in a fixed state a few more minutes so that it ( loskut.) Snain and firmly fixed on the cornea.
After performing the operation, visual inspections and general status Patient who take no more than two hours. The patient can recover home on the same day, but within 7 - 10 days he must accurately comply with all the recommendations that the doctor will give him.
After performing the laser correction of myopia, it is recommended:
After performing the procedure, the hole was done in the front eye wall spontaneously closes. The patient is advised to make a lifestyle over the next few days ( do not wash your eyes with dirty water, do not rub them with your fingers and so on) And the dates of control visits to the ophthalmologist are prescribed, after which they are released home.
The Operation itself is relatively simple, practically does not have contraindications and is performed within 1 day, after which the patient can go home. After performing an operation, an eye surveillance should be avoided ( that is, a long, continuous reading or computer work) For 1.5 - 2 years, as this may contribute to the further progression of myopia. Restrictions ( refusal to visiting the pool, restriction of physical exertion and so on) It should be observed within 2 to 4 weeks after the procedure is performed.
It is worth noting that after the operation, myopia does not eliminate, but its further development slows down or stops. This technique allows you to stop the progression of myopia in 70% of children and in 95% adults. After execution of scleroplasty, it is possible to use other techniques aimed at eliminating myopia ( use of glasses, lenses or laser correction).
Accommodation spasm usually passes independently after eliminating its cause caused. If this does not happen, the doctor can prescribe special drops that relax the ciliated muscle.
For the treatment of false myopia, you can use:
It is also worth noting that the use of these drugs can lead to an increase in intraocular pressure ( Vgud) and provoke the aggravation of glaucoma ( diseases characterized by a persistent increase in VGD). That is why they should be used only by appointing a doctor and after a thorough examination.
Undoubtedly, all vitamins in their own way affect the condition and functions of the eyeball, retina, spectator nerve and other components visual analyzer. Nevertheless, some of them deficiency can significantly disrupt the function of the organ of vision and even contribute to the development of various complications in progressive myopia.
Vitamins at myopia
Name Vitamin | Mechanism of therapeutic action | Method of application and dose |
Vitamin A(retinol.) | We are necessary for the normal functioning of the retina, as well as to adapt the eye in the dark. | Inside, after 10 - 15 minutes after eating, 50 - 100 thousand international units ( Me.) per day. |
Vitamin B1.(tiamine) | Regulates the metabolism in the body, and also provides normal carrying out nerve pulses by nerve fibers, including visual nerve. | Adults are prescribed inside, after 20 - 30 minutes after eating, 10 mg 2 - 5 times a day. Children under 3 years old should take 5 mg 3 times a week ( in one day), And for children from 3 to 8 years old - 5 mg 3 times a day. Course treatment is 20 - 40 days. |
Vitamin B2.(riboflavin) | Removes fatigue and stress in the eyes, and also necessary for normal adaptation of the eye in the dark. | The drug is appointed inside, after eating, adults - at 5 - 10 mg 1 time per day, children - 2 - 5 mg 1 time per day. The course of continuous treatment should not exceed 45 days. |
Vitamin C(ascorbic acid) | Improves the metabolic processes in eye tissues, and also helps strengthen the sclera. | Inside, 50 - 100 mg 3 - 4 times a day for 25 - 30 days in a row. |
Vitamin RR(a nicotinic acid) | It expands the small blood vessels, thereby improving the blood supply to intraocular structures and preventing the damage of the retina at progressive myopia. | Inside, 5 - 50 mg 3 times a day after meals. |
Medical treatment of myopia
Name of the drug | Mechanism of therapeutic action | Method of application and dose |
Calcium gluconate | Increases strength blood vesselsThereby, warning hemorrhage into the retina with excessive stretching of the eyeball. Also this drug Increases the strength of the sclera. | Inside, 500 mg, for 15 - 20 minutes before meals. Children from 7 to 9 years old are recommended to take the drug 3 - 4 times a day, children from 10 to 15 years - 4 - 6 times a day, adults - 6 times a day. The course of continuous treatment should not exceed 10 days. |
Trental | Improves microcirculation in various tissues, including intraocular structures. Improves blood flow. It is prescribed with a high degree progressing myopia. | Inside, after eating, 50 - 100 mg 3 times a day ( not chewing). The course of treatment is 30 days. |
Rutin | Reduces the permeability of small blood vessels, thereby preventing the development of hemorrhages in the retina. | Inside, 1 tablet ( 20 mg) 2 - 4 times a day for 1 month. |
Preventive mechanism special exercises Includes:
At the same time, it is important to remember that the rapid execution of a large number of exercises can lead to the development of various side EffectsSo it is best to start the classes gradually, adding 1 new exercise every day. If visual discomfort or other alarm symptoms appear ( for example, pain in eyes, headaches) It is recommended to reduce the load or temporarily stop performing exercises. If the specified symptoms do not pass within 2 - 3 days, you should consult with your doctor.
Myopia may complicate:
With a high degree of myopia, the distance on which a person can clearly focus both eyes is limited. When such a patient tries to look at more distant items, the accommodation apparatus relaxes as much as possible, but the images of objects still remain fuzzy. As a result, the voltage of the glasses, which try to "configure" both eyes on a clear image. However, it is not possible to achieve this during myopia. Over time, the eye muscles are overstrained and pathological changes begin to develop, as a result of which the squint arises.
The correction of this state may require considerable effort, but it should be started only after the correction of myopia, since otherwise the treatment will be ineffective.
It is also worth noting that during the progression of the pathological process, damage to the blood vessels of the eye shells is possible, as a result of which hemorrhage in the retina can occur, which can also lead to the death of photosensitive nerve cells and visual impairment ( up to the development of blindness).
Myopia is a high degree - this is a severe pathology of the eyes, which leads to their dysfunction and other consequences. Myopia is also called myopia.
Myopia does not make a very high degree to see items that are at a distance. The patient distinguishes clearly objects only at close range. This is due to the fact that with the pathology, the eyeball of the patient is lengthened. As a result, the cornea is strongly distinguished from the rear eye zone. Because of this, the defer of the light flux is wrong. Rays are concentrated not on the eye retina, but in front of it.
Measuring the violation of the functionality of the eye is determined in diopters. When the patient is myopia, the "-" sign is set before the numerical meaning of the diopter. Myopia with a high degree begins with - (minus) 6 diopters.
Symptomatics of any degree of myopia manifests itself equally. Only ophthalmologist can determine the exact number of diopters.
Often, myopia is highly transmitted at the genetic level. If the Pope and Mom have this pathology, then in 50% of cases the disease passes and their kid. 8% of young children develop acquired myopia. Many parents are interested in whether it is necessary to treat a highly high degree in pregnancy, can this somehow affect childbirth? Myopia is even 3 degrees, without complications, allows you to give birth to a natural way (without cesarean section). Disease visual organs May develop for the following reasons:
Also, the pathogenesis of the disease can wage in a certain structure of the visual apparatus:
It's not rare, a person with myopia has not even suspected of the disease for a long time. Pathology is detected only when inspected by an eyepiece. As mentioned earlier, the main symptom is the blurring of the contours of the objects that are located in the distance.
People with myopia will not be able to see for example the bus number, price tags in the stores at a decent distance, the screen of the TV and so on. According to the legislation of the Russian Federation, sick people of a call age with vision from - 6.25 diopters are exempt from service in the army.
By the nature of its development, the disease has three types:
With astigmatism, the cornea has a deformed form. Myopia is a high degree with astigmatism (also called myopic astigmatism) is a specific variety of the disease. With pathology in the eye, myopia is present.
The light stream, when the visual body penetrates into the patient, is not concentrated at one point on the retina (as in healthy organs), and in several. In this case, part of the picture concentrates at the point before the retina, and the other part on the retina itself. Or the picture is formed in a pair of points in front of it.
Such pathology is considered a combination of astigmatism and myopia (minor astigmatism).
Vision at astigmatismTo diagnose and determine the degree of myopia for only an ophthalmologist. Also, only a specialist may appoint effective treatment.
Diagnosis of the disease is as follows:
In medical practice, the treatment of myopia is practiced by highly surgical intervention. To assign the necessary therapy, the ophthalmologist must determine the degree of myopia, and the ability to adjust. Thanks to the diagnosis, the oculist has the ability to assign effective treatment.
It is important to understand that it will not be possible to fully cure the myopia of high degrees or lenses, it will have to seek help to laser correction.
Treatment is applied to high degree pathologies, up to minus twenty diopters. Lensenktomy is used in such cases:
In this case, lens resection with the replacement of it to unnatural with the desired optical force. This is due to the fact that the visual apparatus is not able to concentrate the picture on the retina without a lens.
There is also a phacoemulsification operation. With a submission of a high stage, a lens is used with a minus value that is introduced into the eye. The operational impact is performed with the help of local, drip anesthesia. It is well tolerated even children of small age. All the actions of the surgeon performs through a self-metating very small incision of 1.6 millimeters, to which you do not need to apply seams. This operation is quick and there is no need to stay in the hospital.
Today there are many artificial crystalikovwhich can be selected not only on the basis of degree, but also by age and profession. The most sought after:
This technique is used only when the lens fitness is not yet lost forever. Lens in this case can be embedded without resection of a natural lens. It is very similar to the adjustment of contact lenses. Only contact lenses are put on top of the lens, the fakyers are embedded inside the eye apparatus.
Keratoplasty is an operational intervention that restores the appearance and functionality of the visual apparatus, eliminates injuries of various nature and different pathologies of visual organs. Treatment is to replace the natural organ for artificial or donor. With the help of computer simulation creates the necessary appearance.
Effective means to restore vision without operations and doctors recommended by our readers!
Myopia is a high degree of a severe disease, which is due to a violation of the functional features of the organs of vision. The problem is exacerbated by the high probability of unpleasant consequences. In people who suffer from this ailment, there is a different shape of the eyeball that resembles an oval due to the elongation of the body. Such a location leads to the fact that the cornea is at a high distance from the back of the eye, where the retina is located. This phenomenon entails an anomalous refraction of light rays and a focus disruption. The disease is classified in degrees, there are three of them all over: weak myopia (up to 3 d), average (up to 6 d) and strong - high-degree myopia (more than 6 d).
People having a high degree suffer from several additional symptoms:
If the disease is not congenital in nature, it is most often formed at the moment when the growth and development of the organ of vision (7-12 years) is observed. When a person reaches 20-22 years, vision by this moment can stabilize independently. By itself, this pathological process is not dangerous, but the consequences that arise from its fault are made in themselves a serious threat to life and health.
There are several health difficulties that may entail a high-degree myopia disease:
This degree of myopia can cause complexity absolutely at any age, even if the phenomenon is subject to surgery. Such consequences are associated with the fact that there is no possibility of competent adjustment of the form of an organ of vision, which was formed because of myopia. Children and adults must regularly undergo surveys at the attending specialist - an oculist who will track changes in health, assign correction measures.
There are several factors contributing to the aggravation of the course of the disease:
So, myopia will highly develop under the influence of certain causal factors and features.
For the appointment of a literate medical complex requires a series of diagnostic eventswho are necessarily held by an ophthalmology specialist. They include several species and research areas:
With any myopia, the consultation of the ophthalmologist is mandatory. Only an experienced doctor will be able to appoint a full-fledged medical complex and consult on any issue related to treatment and diagnosis.
Myopia is high - serious diseaserequiring professional treatment. The main task of the doctor under this myopia is to slow down the development process of the ailment and prevent all sorts of complications. First of all, patients should avoid serious visual and exercise, do not lift gravity, observe the principles proper nutrition. It is also important to obtain a sufficient number of vitamins for vision. They are contained in vegetables and fruits, as well as in many breams. Special popularity in myopia enjoy plants like blueberries, carrots.
High Degree Myopia Correction Methods
Treatment of this degree of myopia can be any, most often resort to the following methods:
Complicated myopia can be eliminated by special lenses, the essence of the technique is that at night a person wears lenses, and in the day - to stay without them and at the same time possess good eyesight, that is, these lenses are removed in the morning, and the cornea can save its form during the whole day.
So, we looked at what it is - a high stage of myopia, and what methods of treatment exist. However, there is the possibility of therapy through surgical intervention.
The progressive myopia of both eyes or one organ of vision implies the possibility of a situation in which the correction is not possible, in this case there are all the testimony for surgery. It is carried out in several directions.
Laser correction allows you to eliminate vision dysfunction up to 15 diopters. This operation is the most common degree in myopia, as part of this procedure, it is assumed to change the curvature, which entails the change in the optical force of the entire eye.
If the disease begins to progress, and its complicated form appears, an operation is carried out to replace the lens. It allows you to fully cure the most difficult form of the disease up to 20 diopters. The implantation procedure of intraocular lenses implies an adjustment of the disease by myopia above 20, up to 25 D.
All operational interventions aimed at vision correction can be carried out only in humans with a non-progressive form of the disease, as well as with a phenomenon that is suspended at least for a while. With complicated myopia, a high degree should pay attention to alternative methods of therapy.
With strong myopia, when surgical treatment is carried out, after surgery can manifest unwanted consequences. With myopia, high degree of treatment implies side effects:
