Focoemulsification of cataracts with IOL implantation is a universal microsurgical operation, which allows to restore vision by a minimally invasive path with destructive changes in the lens of various etiology.

The Facoemulsification method was developed as early as the 60s of the last century, but for a number of reasons did not receive widespread proliferation until recently. At the moment, the method of extracapsular extraction of cataract (facoemulsification) and the installation of intraocular lenses (IOL) is considered the most priority method of restoring vision during damage to the lens of any etiology.

Benefits of the method

The main advantage of the facoemulsification of the cataract is the extracapsular crushing of the lens kernel. This allows you to prevent or significantly reduce the risk of perforation of the membrane of the vitreous body.

Micro is largely reduced by the patient's rehabilitation periods compared to the implementation of traditional access. No seams are required and the likelihood of complications after the operation is largely reduced.

Several times decreases the degree of induced caused by surgery.

Modern phacoemulsifiers (devices for the extracapsular crushing of the lens) have several degrees of exposure, which allows you to control the power depending on the lens density. Thus, the likelihood of injuries located near tissues decreases.

Anesthesia

Facoemulsification is considered a painless operation, since the crystal does not have nerve endings. For local pain relief, ophthalmic drops with anesthetic effect are used during puncture and conducting manipulations:

• Tetrakain;
• Alkaine;
• Proparakain.

Most ophthalmologist surgeons prefer to conduct injection anesthesia extracular muscles of the eye to prevent rotation eyeball.

Conducting an operation

Facoemulsification of cataracts with IOL implantation implies the holding of two phased procedures:

• extracapsular cataract extraction with subsequent aspiration of the lens;
• implantation of intraocular lenses.

In the limb area (schgle and cornea compounds), several cuts are made with a diameter of 1.2 mm to 2.2 mm. The tip of the phacoemulsifier (hollow needle) is introduced through the main (the largest) cut. Crushing the kernel of the lens by high-frequency effects and the simultaneous aspiration of crustal masses by a vacuum method.

The intraocular pressure is stabilized using a liquid exchange system associated with a phacoemulsifier, which comes with sterile isotonic viscoelastic (sterile gel-like material).

Iol is introduced into the cavity of the capsule bag by two main ways:

• by means of an injector with a hollow cartridge - the lens is located in the cavity in the rolled state and is automatically repeated when the tip is removed;
• using tweezers for implantation and retention of an intraocular lens.

The implantation method is chosen on the basis of anatomical features Patient, qualifications of the surgeon-ophthalmologist and other parameters.

Sections after manipulations are considered self-metric, i.e., not requiring the imposition of seams. Aseptic bandage is superimposed on the eye. The total time of the operation does not exceed the half an hour, and often it is only 15-20 minutes.

Postoperative period

After the phacoemulsification and implantation of artificial lens do not require stationary observation. After 2-4 hours at the completion of the operation, the patient can go home. There is an outpatient treatment with a weekly visit to an ophthalmologist. Rehabilitation passes quickly, disability is restored after 7-10 days. Of the drugs are prescribed:

• Tobradex;
• Indocollier;
• Maxidge;
• Cornelgel.

Complications

Most complications after the procedure are associated directly with the Cataract Facoemulsification. In some cases, there is a damaging effect of high-frequency oscillations on the endothelium of the cornea, which can lead to a cornea edema in the early postoperative period. Especially if the density of the cataract removed was high.

Other complications in most cases occur against the background of complicated by the associated pathologies of cataracts:

• glaucoma;
• (myopia);
• common eye diseases, including infectious;
• diabetes and damage to the organs of view on its background;
• weakened ciliary ligament (hanging crystal circular bunding).

The average percentage of risk during facoemulsification of the cataract is about 5%. The acuity of view after this procedure increases by 15-20% in comparison with the classical removal of cataracts through large cuts.

In order to learn more about Cataract and other eye diseases that cause their causes and treatments - use the convenient search on the site.

Good day, dear readers! There is quite a lot various diseases The organs of view, but thanks to the efforts of ophthalmologists, methods of treating each of the pathologies were developed. One of the most common diseases of the eyes of adults and children is cataract - clouding in general or individual parts of the lens of the visual apparatus, which without the necessary intervention leads to full blindness.

Such a pathological condition needs mandatory correction. In the category very secure methods Therapies include Cataract Focoemulsification with IOL implantation, or intraocular lenses. Next, I will introduce you to the characteristics and features of the procedure, and you will learn about the results of the treatment and the postoperative period from the real experience of patients with cataracts.

Facoemulsification is considered the most reliable, safe and least traumatic method of therapy of organs of vision, affected by the cataract. To understand why this surgical method has earned a similar status, you need to find out all the advantages of the FEC method and understand what it is. It is this method that most leading ophthalmic clinics with patients with eye pathology, which manifests itself to the cloud of a crystal body.

So, the FocoEmulsification of the cataract (FEC, FAKO) is a procedure for removing a lens from the eyeball and placement of an artificial intraocular lens, or ol. In the process of operation through the tip-needle of a special apparatus, an ultrasound penetrates the eyeball, which crushes the core of the native eye lenses. The benefits of the FEC method include:

• therapy of all types of cataracts;
• operation is carried out in outpatient conditions;
• no need for seams;
• practically excluded complications - two cases are possible from one hundred;
• use of local anesthesia;
• short postoperative period;
• high visual acuity after surgery;
• minimum list of contraindications for the procedure.

Facoemulsification is a painless operation in the eyes, because the lens does not have nerve endings, and, it means, and any pain is completely excluded. In the process of operation, patients may only feel a slight tension or pressure in the eye.

FEK operation stroke: stages of the procedure

First of all, the patient should undergo a complete examination from an ophthalmologist and perform the A-scanning procedure to calculate the parameters of the crystal body. The doctor prescribes the patient to be needed before the operation.

Intraocular lenses for FEK procedure: classification

The main stage of the operation to remove cataracts by the FEK method is the implantation of lenses (IOL). There are several varieties of implant that helps ophthalmologists to eliminate various pathology of the organs of vision. Among Iol distinguish:

• accommodating - for people whose work is associated with auditoriums;
• multifocal - presbyopia correction;
• aspherical - for people in 40 years;
• monophocal - improved long distance;
• toric - correction of astigmatism.

The price of IOL is not included in the total cost of the operation. They choose a doctor after a complete examination of the patient. The cost of the surgical procedure to remove cataracts based on ultrasound depends on the city, the qualifications of the doctor and ophthalmologic clinic. On average, it is 25 thousand rubles, and the price in Moscow - from 40 thousand rubles.

After surgery, the patient may seem that the vision has become worse, but this should not be frightened, because the eyes need to restore time. The main thing here is to adhere to the recommendations of the doctor, to care for the agencies of the vision independently at home and regularly go to the clinic inspections.

Video about how to intervene

The video explains the fact that the doctor makes an operation. Also, it is described that the procedure is carried out when the disease matures. The fact is that there were no facoemulsifiers before. These drugs were previously absent, so before the intervention was carried out by conventional surgical instruments. I advise you, before interfering, learn about the operating all that is possible.

conclusions

Before making a decision regarding the surgery, I recommend that you find out what it is for the FEC procedure, its contraindications, advantages, side effects, Cost and stages, as well as familiarize yourself with network information, explore the reviews. If you have already encountered a problem and allowed it, then you will definitely share your experience - leave comments under the article! Take care of yourself and be happy! Sincerely, Olga Morozova!

Artificial lens (intraocular lens) is implanted in the place of a natural lens in the case when he loses its functions. For example, during an operation to remove cataracts, when a natural lens transparency, and with refractive replacement of the lens, when an intraocular lens allows you to correlate myopia, hyperopia, astigmatism high degrees. The intraocular lens placed inside the eye performs all the functions of a natural lens and provides the necessary visual characteristics.

How is the artificial lens?

As a rule, artificial lens consists of two elements - optical and reference. The optical part of the artificial lens is a lens made of transparent material, biologically compatible with eye tissues. On the surface of the optical part there is a special diffraction zone, which makes it possible to obtain a clear image. And the support portion allows reliably to fix the artificial lens in the human eye capsule. Implantable intraocular lenses do not have a "shelf life" and do not require replacement, providing the necessary visual characteristics for many years.

Crystal Located between the iris and vitreous body Eyes, in good condition it is transparent and flexible.

The main properties of the crustal

Transparency. The natural lens lens is a natural lens that refracts the rays of the light and focus the image on the retina. Transparency provides crystalline protein-incoming crust.

Flexibility. In order to be equally clearly seen in the close and far distance, the so-called is activated. accommodation mechanism: The crystal of the eye with the help of the muscles is bent and "enters the focus" to the items. With age, the elasticity of the lens and the holding muscles decreases, and the natural accommodation weakens.

In the structure of the lens there are no vessels and nerve endings, its supply of nutrients is due to intraocular fluid. The diameter of the lens of an adult is about 9-10 mm, the thickness is 3.6-5 mm (depending on the voltage of accommodation). Crystal Located in a thin elastic transparent capsule.

What leads to the loss of crust properties

• TO age hyperility - loss of crystal ability to bend and cause focus, providing eyesight at close range.
• To the age cataract - the closet of the lens caused by the processes of aging in the body.
• To the congenital cataract - the closet of the lens caused by congenital defects.
• To crystal astigmatism - the wrong form of a lens, which does not allow the light to focus at one point.

Attakia is rarely found - the absence of a lens lens due to injury or operational intervention.

The appearance of intraocular lenses (artificial lenses), which are used in the treatment of cataracts and in refractive surgeons, doctors are largely obliged by Garolda Ridley. During the Second World War, he, conducting surveys by pilots who won the eyes, noticed that when plastic fragments hit from the windows of the aircraft's cabin, even if they were in the eye for a long time, there were no inflammations. This discovery helped in developing material for artificial lenses (lens), which were widely used in ophthalmology.

In November 1949, Ridley implaned the first artificial lens from polymethyl methacrylate (PMMA), which was an accurate copy of the human lens. Despite the imperfection of Ridley's lens, his idea became a genuine revolution in ophthalmology. In 1999, the 94-year-old Harolde Ridley Queen Elizabeth was awarded a knightly rank.

In what cases is Iol implanted?

Intraocular lens (artificial crystal) is implanted instead of a natural lens:

• in the treatment of cataracts, when the natural leaving of the transparency is replaced by artificial;
• to correct the high degrees of myopia, hyperopia or astigmatism (refractive replacement of the lens), when the natural refraction of the lens is insufficient.

The Eksimer clinic is following the latest developments in the field of intraocular lenses (IOL) and offers patients only high-quality models. Properties of modern intraocular lenses make it possible to solve several vision problems at once: get rid of cataracts, from myopia, age-related hypocrium, astigmatism.

Properties of modern intraocular lenses

• Optical characteristics.

​ Each artificial lens has the necessary optical characteristics to ensure good vision. The optical force is calculated individually for each patient, based on the features of its visual system and the goal of surgical intervention.

• Bio-compatible material.

​ Materials from which modern intraocular lenses are manufactured are biologically compatible with eye tissues, do not cause allergies and eliminate the possibility of rejection. Now the most commonly used acrylic, hydrogel, silicone and collaim lenses.

• Flexibility.

​ Modern intracular lenses are made of flexible material. The flexibility of the lens makes it possible to place an artificial lens inside the eye in the twisted state with a special injector through a reduced micro-suite size of only 1.8 mm. The lens is independently unfolded and reliably fixed inside the crust capsule bag.

• The structure of lenses

​ Such a lens has a single particular structure of optical and reference elements. In modern lenses, they are made from the same biocompatible material.

Three-component lenses

​ As a rule, modern intracular lenses are equipped with a so-called yellow filter. The natural human lens has special protective properties that protect the retina from the negative impact of ultraviolet rays of a certain spectrum. The "yellow filter" is similar to the natural lens filter, and the intraocular lens protects the retina as well as the natural lens of the eye, which is especially relevant in old age.

• Correction of spherical distortion.

​ To obtain a better image in the dark time, in conditions of insufficient illumination, intraocular aspherical lenses of spherical distortion correction lenses are specially developed. They help to avoid the appearance of halis, reflections, lights.

• Correction of astigmatism.

​ Often, a person simultaneously with other problems with vision (myopia, cataract) there are astigmatism, and implantation of intraocular lenses with conventional optical characteristics in this case is not enough. In such situations, thorical lenses that corrective astigmatism are used.

• Correction of age limblessness.

After 40 years, each person has a deterioration in the accommodation process - the ability of the lens to quickly change the focus in order to equally clearly see objects as near and away. With age (even if all his life was excellent vision), the crystal eye becomes less flexible, loses the ability to quickly change its curvature, so glasses are already required to work near person. Modern lens models - multifocal (pseudo-forming), trifocal at the expense of the special design of the optical part allow you to see well both on both close and far distances, performing the functions of natural lens, and get rid of wearing glasses. Additionally distance

Modern models of intraocular lenses have a non-one property, but several somewhat combine in themselves. Their combination is selected, based on the tasks of the treatment and wishes of the patient about the quality of vision. For example, all models of lenses implanted in the EXIMER clinic, flexible, from a biocompatible material, most have a "monoblock" design. And other properties, for example, distortion correction, are particularly relevant for professional drivers who require good vision at any illumination.

Types of intraocular lenses (IOL) in the Clinic "Excimer":

How is an intraocular lens chosen in the "Excimer" clinic?

In the clinic "EXIMER", the selection of intraocular lenses passes individually on the basis of these thorough diagnosis of the patient's visual system. To calculate the optical parameters of the lens before operations (about cataracts or refractive crystal replacement), an unique optical coherent biometer "IOL-MASTER" (Zeiss, Germany) is used. This calculation is especially important in implantation of high-tech lenses with complex optics (multifocal, toric) to obtain maximum visual characteristics. When selecting lenses, many other parameters are taken into account: the age of the patient, its lifestyle, occupation, the profession, wishes for the quality of vision and so on. As a result, the patient receives a new quality of auditorium.

Cataract is an eye disease, the main essence of which is to gradually cloud the lens, which sooner or later leads to an absolutely painless decrease in sharpness or even complete loss of vision. The only way to change this situation is the removal of a clouded lens and installing an artificial intraocular lens in its place (IOL). Facoemulsification - one of the species surgical treatment Cataracts. This type of surgical impact on the disease is widespread due to its effectiveness and a small amount of complications. The use of ultrasound energy in anatomically rather limited structures of the front segment of the eye is an important advantage of the Facoemulsification operation with IOL imaging before other methods of surgical treatment. This operation is becoming increasingly popular, as it is safe, easy to perform and gives an excellent result.

Facoemulsification in the treatment of cataracts

The methods of surgical treatment of cataracts have changed dramatically over the past three decades. Most clinics do not use intracapsular cataract extraction, as the preferred method of treating this disease is extracapsular extraction. Small cuts have recently become the standard in the microsurgery of the eye and the facoemulsification is now the method of choice for most ophthalmoshurgeons. Along with these achievements, improved materials and designs have appeared for implanted during the operation of intraocular lenses (IOL). Through the use of modern technology and equipment, this operation is characterized by increased safety and efficiency.

Advanced surgical methods for removing the front capsule lens reduced the frequency of both intraoperative and postoperative capsule complications. Cataract removal previously performed primarily in the front chamber is now performed in rear chamber, reducing the risk of damage to the endothelium of the cornea during the operation. Folding intraocular lenses are placed in the eye through a smaller incision, which further reduces the recovery time.

Purpose of the operation and testimony for facoemulsification

On the very early stages Cataract Development People begin to complain about slight turbidity due to the violation of the passage of light rays through the lens and incomplete their retina. As the pathological changes progressing changes, the obstacle on the path of the rays is becoming more comprehensive. As the severity and deterioration of the quality of life, the doctor may recommend the Facoemulsification of Cataracts.

The main goal of the Focoemulsification operation of cataracts is an improvement in sight and, as a result, greater comfort when performing such routine manipulations as reading books or driving a car. Previously it was believed that the operation should be carried out only after the total ripening of cataracts, people suffered for a long time poor vision. Now the decision on operational treatment is accepted by a mutual doctor and the patient and can be carried out at any stage of the disease.

What to expect from the procedure

Focoemulsification is a kind of extracapsular extraction of cataracts, procedures, during which the lens and the front of its capsule is removed. Earlier, the extraction technique implied broad cuts and a long recovery period. The Cataract Focoemulsification Operation was first introduced into practice in the 60s. The last century in order to make interference less traumatic and more efficient.

Anesthesia during facoemulsification is mainly local - eye drops With an appropriate drug or retrobulbar administration of painkillers. During the intervention, a person does not feel pain, but it is in consciousness, there may be insignificant discomfort.

Allocate the following steps of the operation:

• Ophthalmoshururg makes small cuts on the cornea, the length of them is not more than 3 mm. Then a special viscoelastic fluid is introduced into the cavity of the eye.
• The specialist carries out a microscopic circular incision on a capsule, in which a changed lens is located. This stage of operations is called Capsulorexis.
• The titanium needle is introduced into the patient's eye, emitted through it ultrasonic waves crushed turbid lens. This is the main stage of the Cataract Facoemulsification operation.
• The crushed material is aspiring through a special hole at the end of the needle.

Intact during the operation remains the rear capsule, since it is it used to fix artificial lenses. It is placed on the vacant place, and then a new IOL is recorded. The need for seams is missing. Microscopic cuts are very quickly healing independently. The eye impose a sterile gauze bandage, the recommendations for removing it gives the operating ophthalmic surgery.

The whole procedure usually takes 20-30 minutes. At the end of the patient's work, some time is observed in the clinic, after which they are released home with relevant medical recommendations.

Postoperative recovery

The first day after the operation Facoemulsification of cataracts and implantation of IOL, it is desirable to be in full peace and observe the bed regime. Normal is the presence of a moderate painful syndrome in the patient in the postoperative period. To relieve it, doctors prescribe paracetamol, nonsteroidal anti-inflammatory drugs inside or in the form of eye drops. With a serious deterioration of the state, the appearance of such clinical symptomsAs non-supported pain in the eye, strong nausea or vomiting, you should immediately consult a doctor.

The reduction of vision after the facoemulsification of cataracts with IOL imaging occurs gradually. First you can see dark spotswhich disappear within a few weeks. Fears should not cause increased photosensitivity and the presence of small hematomas. After 1-2 days, you can return to your usual activity, sometimes doctors recommend wearing special glasses to protect your eyes.

Regular visits of the patient in the clinic to control the position of the implant and early detection of complications. After a facoemulsification, the main part marks significantly an increase in visual acuity and better perception of colors. An intraoperative installation of IOL can solve other problems, such as the need to correct myopia. After the cataract phacoemulsification was carried out, people return to normal life, they perform such daily tasks as reading, driving a car or sports. In all this, they were deviated before intervention due to the pathological cloud of lens and loss of clarity.

TO possible complications after the operation include accession bacterial infection (endophthalmites), cystic edema of Makula, cornea swelling, hemorrhage and retinal detachment. Focoemulsification of cataracts with IOL imaging is currently modern high-tech intervention, which significantly reduces the risk of unwanted reactions and returns good vision for a long time.

The most reliable, efficient, safe and least traumatic method of treatment of the organs of the visual apparatus with cataract disease is the facoemulsification of cataracts with IOL implantation.

Facoemulsication of the cataract is the process of removing the crystal body from the eyeball, upon subsequent replacement for an implanted artificial intraocular lens.

Reliability and dignity of operations on other types of surgical intervention are represented by the following factors:

1. Removal of practical all types of cataracts.
2. Thanks to scientific and technical progress in ophthalmological practice There have been a large number of different equipment that helps in the cure of patients.
3. The operation is outpatient. This advantage is also explained by scientific and technical progress.
4. New materials used to create implants are also widely used in ophthalmic surgery. Because of this, the operation occurs in a short period of time, usually, about half an hour, after which the operated patient can immediately go home.
5. Operation is painless and does not require seams. The lens of the eye there are no nerve endings, and therefore, and any pain is not felt.
6. Cataract phacoemulsification operation is most often happening against the background of local anesthesia. In addition, the removal of the lens is possible with minimal cuts, which allows it to be performed without the subsequent imposition of seams.
7. Healing occurs independently.
8. High speed restoration of health organs. In the postoperative period, vision to the patient is returned to a fairly short time interval.
9. Maximum performance. The advantage is characterized by a properly selected artificial lens and high quality surgeon with a surgeon with a phacoemulsifier. Performing these requirements ensures maximum improvement of visual acuity.
10. High degree of visual acuity in the eyes after surgery. A person returns good eyesight due to the replacement of a natural, but infected lens with an artificial analogue. The main features of artificial crystal bodies are the magnificent properties of color reproduction and contrast.
11. Minimum number of restrictions for the operation. In order for a person to be able to carry out this operation, there are only a few contigoing factors, the main of which is a rather old age. There are no more restrictions on conducting surgical intervention.
12. Short-term rehabilitation. The postoperative rehabilitation period ends in a week, a maximum of ten days. After that, a person calmly start labor activity, observing only some restrictions, expressed in the use of eye drops.

Facoemulsification of cataracts is considered one of the safest types of surgical intervention.

General steps of the operation

Let's consider the process of operation:

• The basis of the operation is the removal of a turbid lens, affected by cataract, and replacing an artificial analogue. For this, the doctor is made as minimal incision, which does not exceed the pair of millimeters.
• Further, the lens, complicated by pathology, is crushed using an ultrasound or laser without disorders of the capsule integrity, and then all particles are removed, or rather sucks from the eyeball.
• The next step in the operational process is the introduction of an intraocular lens imitating a natural lens. She independently unfolds inside the eye and makes it possible to complete the restoration of health organs. Each crystal from artificial materials is selected only with a detailed individual examination patients before the operation.
• Subsequently, any seams are imposed, since it is delayed due to the minimum cut itself.

The rehabilitation period is only a few days. A person fully restores the visual apparatus without subsequent restrictions.

If we consider this operation step by step, then several stages can be distinguished:

1. Stage 1st - Piercing and sucking of a natural slurry lens;
2. Stage 2nd - implantation of flexible artificial lens;
3. Stage 3rd is an independent occupy of an intraocular lens in the eye cavity, as well as sealing the cut without the imposition of seams.

The procedure for removing cataracts occurs in a specially designated operational, in sterile conditions and lasts no more than half an hour. After the expansion of pupils due to instillation medicinal preparations Local anesthesia is used to the person operated by man. In case the patient is amazed by an ailment of both eyes, its vision between the two operations will be not balanced.

This method of recovery of vision is also used in conjunction with other surgical operations, for example, to adjust vision during astigmatism.

Intraocular lenses

As mentioned earlier, in the process of fulfillment of facoemulsification, an implantation of any kind of intraocular lens is made. At the moment, a large number of lenses such that helps solve practical all problems with the organs of the visual apparatus are known. The main ones are:

• Monofocal;
• Accommodating;
• Multifocal;
• Aspherical;
• Toric.

Monophocal lenses

This type of lenses is the most frequently used in large number of operating processes. The main advantage of the lenses is that after its implantation, the patient increases at times of visual acuity, intended for consideration of remote objects. But minus also has. The problem is that, solving the issue with the possibility of looking into the distance, a person has to be either glasses or contact lenses in the form of additional correction for consideration of near-locked items. In addition, the regularity will be the emergence of astigmatic points causing distortion of the visible picture.

Accommodating lenses

It is used in a surgical operation of a man's wishing, which refuses to carry glasses or contact lenses when working with close-minded items (computer, books, etc.).
As a result of the operation in the patient there is an improvement in the acuteness of organs of vision and distance, and at close range. That is, the ability of accommodation characteristic of young age is simulated. it the best way For people whose lifestyle is associated with large volumes of viewing work.

Multifocal lenses

This kind of artificial implants makes it possible to consider it the surrounding items from any distance, from a few millimeters to a couple of kilometers. The principle of operation of these lenses is very similar to the one that is used in multifocal glasses or contact lenses. Multifocal intraocular lens is a good option for solving eye health problems, expressed as presbyopia.

Aspheric lens

Completed option used by surgeons of foreign countries. Reviews of people operated on show that their eyesight and its sharpness are compared with the vision of an eagle or falcon. It is manifested in high quality view, as well as an increase in contrast sensitivity. They advise this corrective implantable adaptation to people with age forty years and more.

Toric lenses

The best option for correcting astigmatism. The effectiveness of lenses is expressed in the possibility of delivering a person from visual pathology reaching twelve diopters. Manufacturing is made strictly according to the individual features of the eyes, where will be implemented in the future. The main disadvantage of the toric lenses lies in a fairly high cost and is manufactured for a long time, approximately, on the manufacture of lenses takes at least two months.

To date, such a surgical operation is divided into two types depending on the way of exposure to the cause of pathology:

You can right on the right, which compares two types of facoemulsification (ultrasonic and laser). We recommend clicking on the picture and explore it.

Ultrasonic Facoemulsification of Cataracts

1. In the case of ultrasonic phacoemulsification of cataracts, the operation is performed using a diamond device for cutting the cornea of \u200b\u200bthe eye.
2. Next, the doctor introduces the viscoelastic - a substance that protects the internal structures that are inside the eye cavity during the operation from the effects of ultrasound waves.
3. After that, through the incision of the cornea, the surgeon introduces the probe designed to change the condition of the affected lens from the solid phase into the emulsion.
4. Next, an intraocular lens is introduced, and after the end of the main part of the process, vexelasty with irrigation mortar is washed.

At the moment, there are several types of ultrasound used during surgical operation. The most efficient and most safe is torsional ultrasound. Applying such a type of ultrasound waves, the time is reduced and the safety of fakoemulsification increases compared to those used traditionally.

Advantage this method The fact that the destruction of the affected lens occurs gradually, the entire process of the operation passes using the needle movements that are oscillatory. In this case, the feeling in the introduction of a new lenses is relatively pleasant.

Laser facoemulsification of Cataracts

Such a method of treating organs of vision from cataract is considered the most progressive and high-tech. It is often used in world-scale ophthalmological practice.

The operation applies a femtosecond laser whose beam focuses at different depths. Accuracy - several microns. When exposed to the eye, the formation of a layer of microbubbles, separating tissues. Thus, cutting is replaced by the stratification of the cornea.

The main distinctive feature of the operation using the ultrasound laser is a way to form access to the internal structures of the eyes, lens, and besides this, another process of determination of the crystal body. They occur contactless.

The process of carrying out the operation is different:

1. Previously before the operating process is performed optical chereten tomography To remove the parameters of the organs of vision. With this, it is calculated and creating a plan of the operation.
2. In the process of the operation itself, applying a femosecond laser form access to the eye cavity. All microprocesses are recorded by the camera and are displayed in three-dimensional mode.
3. The laser is stratified a lens, destroying it circularly or sectors. As a result, a hole is formed with absolutely accurate centering and smooth edges. IN further application Laser stops. The process of operation continues according to the scenario of the ultrasonic phacoemulsification of cataracts.

The main advantage of this method is the ability to operate patients who are prohibited by an ultrasonic method.

The operation may be allowed by persons who have:

• 50 percent reduction in visual acuity was discovered;
• There are shining halisses surrounding items in sight;
• Double in the eyes;
• There are periodically "flies", "fog" and various spots before your eyes.

Complications after surgery

Both any operation associated with the visual apparatus of a person and after facoemulsification may be some complications, although they are found in extremely extreme cases.

After the operation was observed:

• Postoperative induced astigmatism;
• Inflammatory processes;
• Clouding the inner wall of the lens;
• Corneal swelling;
• Cystoid macular swelling;
• Tear;
• Redness;
• Minor vibration of visual acuity.

Most often, such complications weaken and fully pass over the month. However, if they did not stop during this period, they need to consult a doctor.

The listed complications are only 1% of the total number of operated patients. Also, when removing cataracts with this method, it is worth paying attention to people suffering from uveit and diabetes. To correct complications, we need wearing glasses or lenses, it is possible to carry out a refraction recovery operation.

Contraindications

Prohibited operation in case:

• Oncological diseases;
• Psychological disorders;
• Degenerative diseases of the central nervous system;
• Blood diseases;
