Surgical treatment of cataracts is required when there is a deterioration in vision or serious complications are possible. Before the operation, the patient passes a full examination to fully explore the severity of the disease and choose the appropriate method of operational intervention. Painless and absolutely safe for man Operation in Cataract. How do it, and in what cases does it contraindicate?
Cataract spreads very quickly and can lead to complications in the form of a complete blindness.
Previously, the operation was carried out only with the complete maturity of the disease, but now, in the introduction of new technologies of operational intervention, the procedure can be carried out at any stage of the disease.
This eliminates the possibility of complications.
Indications for the operation are:
Treatment It is advisable to begin already at the first symptoms of the disease, in which case you can choose a more sparing method.
In some cases, the testimony for the operation is the need to preserve 100% of view for professional activity. In this case, for example, the driver of visual visual vehicles at the time of the operation should be 0.5. When such a high definition of view is required, values \u200b\u200bof 0.1 are allowed.
With double-sided cataract, it is started to operate that eye where there is lower visual acuity.
What are the methods of operational intervention?
Operational lens removal intervention is the only way to get rid of cataracts and save vision.
In modern ophthalmology, there are several methods of surgery, which involve crushing lens using a laser or ultrasound.
The operation passes very quickly, while the anesthesia is used. The patient does not feel pain during the procedure itself, and the postreahalitational period lasts quite long.
Types of operational treatment are as follows:
Consider the shortcomings and advantages of each of these types of operations.
During the procedure under anesthesia, the crustal core is removed, and the capsule itself remains intact. The advantage is the preservation of the rear capsule of the lens after the operation. As a lack, it is possible to consider severe trauma. During the operation, a large incision of the cornea is made, then need to apply seams. The recovery period is quite long.
Stages of this method are as follows:
The advantage of this method is the possibility of complete removal of the lens, which avoids complications in the form of repeated development of cataracts. This type of operation is made at high cataract maturity. The disadvantages of this type of surgery for the eye is the falling out of the vitreous body and the fall in visual acuity.
What anesthesia is chosen in operational interference to the eye? Most often make local anesthesia.
If you operate a child, we use common anesthesia (the medicine is administered intravenously). If a person has a standing psyche and can sit at the time of surgery, it does not need to make a common anesthesia. In this case, a person is in consciousness and everything sees enough local anesthesia.
Due to the high traumatic eye, intracapsular extraction is used only in the launched cases of the disease, more often make extracapsular extraction.
Despite the popularity of extracapsular extraction, it begins to push out a new method of surgical intervention, such as facoemulsification. In the past 10 years, it is used almost all ophthalmologic clinics.
What is this type of operation, how is the removal of cataracts of the eye?
The essence of the operation is to remove the magnificent lens and replacing it with an intraocular lens. How does it go? In the cornea, microdava is made of only 1.8 mm in size, and with the help of ultrasound soften and derived from the eye of the crystal. A flexible lens is placed in the lens capsule. It will start in the eye in a bent condition, and in the capsule itself it straightens and fixed.
The advantage is the rapid period of rehabilitation. The seams after the intervention are not superimposed, and the microdoscope itself is delayed and heals.
Consider the procedure for the operation:
In most cases, they make local anesthesia.
After surgery, the patient does not need additional treatment. The doctor appoints eye drops To restore vision. The first month after surgery you need to adhere to prevention measures to avoid complications. You can not drink alcohol, do not strain the eye once again. From reading books and watching TV at first, it is advisable to stay. Also impossible to lift gravity, lean and avoid temperature drops.
Ultrasound Facoemulsification is one of the safest and most effective methods of operational treatment of cataracts. Laser phacoemulsification is also carried out.
Operation itself lasts only 20 minutes, the patient does not feel pain, no outpatient treatment is required. A person may leave the hospital walls on the same day. Already two hours after the operation, the patient begins to see, and in two weeks the vision is restored completely.
Cataract is one of the most common ophthalmic diseases among older people.
This disease is associated with partial or complete closet of lens, as a result of which only a small part of the light rays fall into the eye, and the person begins to see blurry and odd.
The eye cataract has a property to progress over the years: People over 50 years old, the area of \u200b\u200bclouding can constantly increase, and the vision will decline all faster.
(Release of 08/17/2010 - see the cataract from 30 minutes of video)
Cataract Eyes is a complex ophthalmic pathology characterized by clouding. Absence timely treatment Thunders of loss of vision. The disease usually slowly progresses in adulthood. However, certain types of cataracts differ in rapid development and can lead to blindness in the shortest possible time.
In the risk group there are people after fifty years. Age-related changes and violation exchange processes In the eye structures often lead to the loss of transparency of the lens. The cause of cataracts may also be injured eye injury, toxic poisoning, available ophthalmological pathologies, diabetes and much more.
All patients with cataract is inherent in the progressive reduction in visual acuity. The first symptom is the fog in the eyes. Cataract can cause bias of items, dizziness, light source, difficulty reading or working with small details. As the progression of pathology, patients even cease to recognize their acquaintances on the street.
Conservative treatment is advisable only at the initial stage of the cataract. It is worth understanding that drug therapy protects against the rapid progression of the ailment, but it is unable to save a person from the disease and return the transparency of the lens. If the lenses are further enhanced, an operation to remove cataracts is required.
In the first stages of clouding, the lens is shown dynamic observation from an ophthalmologist. The operation can be carried out from the moment the patient's vision begins to significantly decline.
Direct indication to conduct a lens replacement operation is a worsening of vision, delivering discomfort in everyday life And limiting labor activity. A specialist is engaged in the selection of intraocular lenses. The procedure is carried out under local anesthesia. In the conjunctival bag before the operation, droplets with anesthetic. Usually the removal of the lens lasts half an hour. On the same day, the patient can be at home.
ATTENTION! In the case of complete blindness, the operation during cataract will not bring any results.
Modern medicine does not stand still, so the replacement of the lens of the eye during cataract can be produced in various ways. The essence of the procedure is to remove the natural lenses. It is turned into an emulsion and remove. Artificial implant is placed on the place of the deformed lens.
Operational intervention can be applied in the following cases:
There are not only medical, but also professional domestic readings for the operation. For employees of some professions, high vision requirements are imposed. This applies to drivers, pilots, operators. The doctor can also recommend a crystal replacement if a person cannot fulfill the usual houses at home, as well as with a significant narrowing of fields.
Any eye operation has a number of restrictions, and the replacement of the lens is no exception. Removal of cataracts with a crystal replacement is prohibited in the following cases:
The ban on the operation of pregnant women and nursing mothers is due to the fact that during surgery, medical support is necessary for the patient. Doctors prescribe antibacterial, sedative, analgesic drugs that may not best be reflected in the state of a woman and child.
Age up to eighteen years is a relative contraindication to the operation. In each case, the doctor accepts an individual decision. It largely depends on the state of the patient.
It is dangerous to carry out an operation during decompensated glaucoma. This can lead to hemorrhage and loss of vision. Surgical intervention must be carried out after the normalization of indicators intraocular pressure.
If the patient has no light, operational treatment is not carried out. This indicates that the retina began to develop irreversible processes and surgery here will no longer help. If during the study it turns out that the vision is partially possible to restore, the operation is assigned.
Complementary factors during operational treatment include:
Most often, the cataract occurs in old age. People have old years often have serious diseases. With some of them, the anesthesia is a great risk for health. Many modern techniques imply the use of local anesthesia, which does not have an increased load on the cardiovascular system.
Problem replacement operation can not be done when infectious diseases
Let's talk about four modern techniques that help to completely get rid of closet of lens.
The operation requires a surgeon of marginal accuracy and concentration. It is prescribed when it is detected to harden in eye media, which is absolutely not sensitive to ultrasound. Laser facoemulsification is not available to many, patients, as it implies the use of special expensive equipment.
Operation can be carried out in extremely complex cases:
Before the procedure, the patient burst anesthetic drops. A healthy eye is covered with a napkin, and the area around the affected eye is processed by an antiseptic.
Next, the surgeon makes a small incision through the cornea. Laser ray crushes a smooth leak. It focuses in the thickness of the lens, while not damaging the cornea. After that, the magnificent lens is split into tiny particles. During operation, patients can see small flashes of light.
Then the capsule is prepared for implantation of an artificial lens (about the rules for choosing an artificial lens). The installation of a predetermined intraocular lens is carried out. Sealing the cut is carried out in a seamless method.
IMPORTANT! During the surgery surgery, the tools do not enter into the eye, which reduces the risk of postoperative complications.
Complications appear quite rarely, they are still possible. Among the negative consequences, it is possible to distinguish the appearance of bleeding, the displacement of the artificial lenses, the retinal detachment. The fulfillment of all the recommendations of the doctor and compliance with the rules of hygiene is the best way to avoid the development of dangerous complications!
Laser facoemulsification does not imply under an obligatory hospitalization. A few hours after the procedure, a person can return home. Restoration of the visual function occurs within a few days.
Nevertheless, some time will have to take into account some limitations. During the first two months, try not to overwrite your eyes. It is better to abandon the driving of the car. To minimize the risks of complications will have to be taken by the doctor prescribed drugs and vitamins.
This technique is recognized as one of the most efficient and safe in the treatment of cataracts. If there is no discomfort in the first stage, then at wishes it can be replaced by a crystal.
Operational treatment is absolutely painless, no discomfort during the procedure does not experience the patient. Ask up and immobilize the eyeball using the tools for local use. Drops with anesthetic effects can be used: alkaine, tetrakain, precaircane. Also for anesthesia injections in the area around the eyes.
With the help of ultrasound, the damaged lens crushed into small particles, turning into an emulsion. Remote lens replaces intraocular lens. It is manufactured individually, taking into account the features of the eye of each patient.
ATTENTION! Related eye pathology reduce the effectiveness of surgical interventions.
During the procedure, the surgeon makes a small incision. This has become possible, thanks high indicators Flexibility of IOL. They are entered into a rolled state, and already inside the capsule are spread and take the right form.
During the recovery period, intensive physical Loads and high temperatures. Doctors categorically prohibit the saunas and baths. It is not recommended to sleep on the side, with which the eye was operated. In order to avoid infection, it is temporarily able to abandon the use of decorative cosmetics. The eyes should not be exposed to aggressive exposure to sunlight, so do not forget about the use of glasses with an ultraviolet filter.
This is a simple traditional technique without the use of expensive equipment. In the shell of the eye, a large incision is made through which the smooth crystal is completely removed. A characteristic feature of ECs is the preservation of a lens capsule, which serves as a natural barrier between the vitreous Tol and artificial lenses.
Extensive wounds imply the overlap of seams, and this affects the visual function after the operation. Patients develop astigmatism and hyperopia. The recovery period takes up to four months. Conduct extracapsular extraction with ripened cataracts and hardened lens.
In the extraction of cataracts, the surgeon has to make a big incision with the subsequent imposition of seams
Most often use a tunnel technique. During the operation, the crystal is divided into two parts and is displayed. In this case, the risk of early postoperative complications is reduced.
Removing seams does not require anesthesia. About a month later, glasses are selected. The postoperative scar can cause astigmatism. Therefore, in order to avoid its discrepancy, injury and excessive physical exertion should be avoided.
Despite the high efficiency of modern techniques, in some cases specialists prefer the traditional operation. EEK is prescribed with the weakness of the ligament apparatus of the lens, overripe cataracts, corneal dystrophy. Also, the traditional operation is shown in narrow pupils that are not expanding, as well as when identifying secondary cataract with the decay of IOL.
IMPORTANT! Vision begins to recover already during the operation, but for full stabilization, time is necessary.
It is carried out using a special tool - cryoxtractor. He instantly freezes the lens and makes it hard. This facilitates its subsequent elimination. Lens is removed with the capsule. There are risks that the particles of the lens will remain in the eye. This is fraught with the development of pathological changes in visual structures. Not remote particles grow and fill out free space, which increases the risk of secondary cataracts.
From the advantages of IEK you can select the available cost, as it eliminates the need to use expensive equipment.
What tests need to pass before the operation? An inspection of the visual apparatus and the whole organism to eliminate contraindications to conduct surgery is carried out. If during the diagnostics were identified some inflammatory processesBefore the operation is carried out a rejection of pathological foci and anti-inflammatory therapy.
Such research is required:
Disinfecting and expanding pupil drops are introduced into the operated eye. Eye drops or injections in the area around the organ of vision can be used for anesthesia.
Selection of artificial lens is a complex and time-consuming process. This is perhaps one of the most responsible stages of training, since the vision of the patient depends on the quality of the chosen lenses after the operation.
Operation in most cases is well tolerated by patients. In rare cases, specialists complain about the emergence of unpleasant sensations, including:
After the operation, the patient goes home. Man impose a sterile bandage on the eye. During the day, he must comply with full peace. After about two hours, the meal is allowed.
IMPORTANT! At first, after surgery, patients should avoid sharp movements, not lifting weights, refrain from alcohol.
For speedy restoration, it is necessary to follow medical recommendations:

Conservative treatment It is to use various drugs capable of slowing down or fully stopping the further progression of cataracts and, thus, to maintain vision on the current existing level.
It is necessary to know that conservative treatment cannot fully lead to the disappearance of cataracts, since the existing turbidity is not resolved under the action medicinal preparations. Conservative therapy can only stop the progression of the process and to ensure the maintenance of vision at the existing level without operational intervention. That is why it is resorted to non-operational methods of treatment. initial stages Cataracts, when the vision does not even suffer significantly, and a person can live ordinary life. Medicines are used to support vision at the current level as long as possible and avoiding the possibility of surgical intervention, which in any case carry certain risks.
Surgery Allows you to completely deliver a person from cataracts, because during the operation it is removed by the clinked mass of the lens. But after the operation to remove the cataract, a person will not be able to see, because The crystal will be simply destroyed, so the mandatory second part of the surgical intervention is the installation of a prosthesis that will allow to see. Currently, both stages of the operation - the removal of cataracts and the installation of an intraocular lens (lens prosthetic) are made during the same intervention. In other words, for one operation, a person gets rid of cataracts and gets a prosthesis that allows him to see normally. And the artificial intraocular lens, which is often called " artificial lens", It will serve a person an unlimited term. Therefore, one day, a remote cataract with an established artificial lens is considered to be fully cured. eye disease.
Considering this state of affairs, ophthalmologists when cataract detection is almost always recommended to produce surgeryguaranteeing full deliverance from the disease and allows you to restore normal vision. However, in the United States and European countries, doctors are not recommended to resort to surgical treatment of cataracts in any cases, since any surgical intervention has a risk of complications, without which it is better to do if it allows. That is why in Western countries, ophthalmologists prefer to treat cataract conservatively, if a person is able to see it normally using glasses or contact lenses. And only in ineffectiveness conservative therapy And the progression of cataracts resort to surgical treatment.
Thus, it can be said that there are states of cataracts, in which the surgical operation is necessary and must be made at mandatory. But there are also other states in which conservative therapy can be carried out, and the operation is not mandatory, but only desirable. Consider the states in which the operational treatment of cataracts is necessarily and desirable.
Cataract surgical operation must be carried out in the following cases:
If the cataract is one-sided, then the question of the operation is solved on the basis of the professional and domestic needs of a person. If he does not need vision with two eyes, he can refuse the operation, but to limit the conservative treatment.
If the cataract is bilateral, then the removal operations are produced alternately on each eye. And first operate the eye with a stronger loss of vision.
Currently, the following types of operations can be produced at Cataract:
Any operation on the removal of cataracts and implantation instead of a crystal intraocular lens is made under local anesthesia. Anesthetics can be buried in the form of eye drops directly into the eye or administered injectable. In this case, the injection is made in soft tissues near the eye.
Since the operation to remove the cataract involves the installation of an intraocular lens, the prosthesis with the necessary properties is selected before surgery. In the world, hard and soft lenses are produced, but currently used primarily soft, since they can be quickly and painlessly introduce through a small incision (1.8 - 2.5 mm). Rigid lenses are inconvenient - for their installation, a large incision is required, requiring the seam impositions after the operation.
Currently use the following types of soft lenses to replace the lens:
Currently, the following drugs are used in conservative cataract therapy:
1. Ready eye drops from cataracts:
In addition, for the successful healing of the cut and prevention of complications after the Cataract Removal Operation, the following rules must be observed in everyday life:
If there is a need, you can wear glasses or contact lenses immediately after surgery, as it will not only hurt, but even on the contrary, accelerate healing.
If the bright light after the operation causes a feeling of discomfort, then it is necessary, even being indoors, put on sunglasses.
At first, after the operation, the picture can be blurred, but after some time (1 - 3 days) the pupil is narrowed, and the vision will become normal.
This method is to instill in eye drops containing lanosterol.. Drops lead to complete resorption of clouds and allow you to get rid of cataracts without surgery.
However, today data drops are applied only in the practice of veterinarians, which reported on excellent results. full cure Cataract in dogs and cats, which have been driving solutions with Lanosterol. Data drops have an excellent therapeutic effect and do not cause side effects.
Currently, the creation of drugs with Lanosterol, which will be officially registered and allowed for use in humans. But for now, on sale in Europe and the United States there are only veterinary drugs with Lanosterol, so people who want to avoid surgery can use them, but, of course, at their own peril and risk.
The most common folk methods Cataract treatment are the following:
