Removal of secondary cataracts with laser contraindications

An unhealthy lifestyle, taking medications, constant use of gadgets, watching TV, reading in inappropriate conditions, genetics - all this creates a huge strain on the eyes and often leads to the most unpleasant consequences. One of them is cataracts. It is believed that it can be completely cured only by surgery, but most people are afraid of surgery like fire. One of the most frequently asked questions is whether cataracts can be treated with eye drops?

Eye drops for cataracts to cleanse the lens

Indications for lens cleaning with laser

The main indication for the use of lens cleaning is the formation of insoluble protein fractions. They gradually accumulate in the lens and settle on the surface of its capsule. The condition must be minor for the procedure to occur.

Complete removal of the lens is indicated if cataracts have formed that reduce the power of vision. Insoluble protein fractions gradually accumulate in the lens and settle on the surface of the capsule. The condition must be minor for the cleaning procedure to occur.

The second indication for the procedure is the lack of results from removing the lens. This means that the patient has developed secondary cataracts. In fact, there is no cataract itself. A layer of fibrous tissue forms behind the installed intraocular lens, which prevents the passage of light rays to the retina.

Causes

Such clouding is usually mild and affects vision to a minor extent. Its frequency can range from 10 to 50% of all operated patients. Many factors can contribute to the development of such cloudiness, including: the ocular pathology accompanying cataracts, the method of performing the operation, the type of artificial lens used and, in rare cases, the lack of experience of the ophthalmic surgeon who performed the operation.

With the development of opacities of the posterior capsule of the lens, the patient experiences symptoms very similar to the signs of cataract development. Therefore, this condition is called secondary cataract.

Symptoms of secondary cataracts

If the patient has had the lens removed, but vision remains reduced, this means that areas of fibrosis have appeared behind the intraocular lens. The patient will have the following symptoms:

• decreased visual acuity, which gradually progresses with an increase in the amount of fibrous tissue;
• pain in the head and eyes when the patient begins to concentrate on objects;
• deterioration in the perception of various colors;
• deterioration in the quality of vision at dusk.

In this condition, it is impossible to carry out a repeat procedure to remove cataracts, since the lens is no longer there. Therefore, laser treatment is used.

Main stages

The laser machine is equipped with a computer on which the operation process is simulated. The doctor determines exactly where the corneal incision needs to be made. The built-in tomograph allows you to see the entire working area during laser cataract removal.

Stages of laser treatment:

1. The person is placed on the couch.
2. Local anesthesia is performed.
3. Drops are instilled to dilate the pupil.
4. Using a laser beam, surgical access is created on the cornea.
5. The lens is crushed using a laser or ultrasound to form an emulsion.
6. The destroyed parts of the lens are aspirated, that is, removed.
7. Rinse the eye cavity.
8. An intraocular lens (IOL) is placed.
9. Final treatment is carried out with antiseptic solutions.

No stitches are needed. Cataract surgery takes 10–30 minutes. If everything went well, the person can go home on the same day.

If a person develops repeated opacification after a while, then laser dissection of the secondary cataract is performed. The essence of laser dissection is to create a hole in the back of the lens capsule and remove the cloudy film. For secondary cataracts, laser treatment is considered the safest method for preserving the IOL.

After surgery, follow the rules of the rehabilitation period and do not refuse the prescribed therapy. This will avoid possible complications and speed up the recovery of the eye organ.

Additionally, see the process of removing eye cataracts using a laser:

Preparing for laser cleaning

Before the procedure, the patient must adhere to the following simple rules:

• do not use medications that the doctor has not been warned about;
• do not drink alcohol 2 days before surgery;
• the last meal should be 8 hours before the procedure;
• Before the procedure, you must thoroughly wash your face and hair to prevent the spread of infection to the eyes;
• The start of using antibacterial drops should be at least 2 days before the procedure.

If all points were completed correctly, this will prevent many complications.

Diagnostics

To determine the causes of decreased visual acuity, the ophthalmologist prescribes a complete examination of all parts of the eyeball. A diagnostic examination for suspected secondary cataracts includes:

• checking refraction (refraction) and visual acuity;
• carrying out tonometry (measuring the level of intraocular pressure);
• examination of the anterior part of the eye using a slit lamp (biomicroscopy), as well as in transmitted light;
• retinal examination with pupil dilation.

If concomitant diseases occur, the doctor prescribes additional diagnostic measures.

Laser lens cleaning

The technique takes no more than 10 minutes. It takes place in several stages:

1. An anesthetic is instilled into the patient's eyes;
2. the person sits in front of the device, his head is fixed;
3. the laser directs a beam through the pupil, removing fibrous tissue;
4. An anti-inflammatory agent is instilled into the patient's eyes and a prescription for the use of antibacterial drops is given.

The entire operation goes quickly, the doctor does not touch the vessels or nerves, so the rehabilitation period is significantly shortened.

Sunday, March 20, 2021 14:57 + in quote book Cleansing the lens of the eye with cataracts: the use of the following techniques helps to resolve clouding of the lens with cataracts. 1) Juice of a fresh plant called “wildflower”, mixed with honey, instill 2-3 drops 2-3 times a day. 2) Take 50 g. eyebright medicinal (or eye herb), pour 1 liter of boiling water, leave for 2 hours and take half a glass 3-4 times a day. Rinse your eyes with the same infusion for inflammation of the eyelids and clouding of the cornea. 3) Pour two teaspoons of calendula flowers into 2 cups of boiling water, leave for 30 minutes and strain. Take half a glass 4 times a day, and rinse your eyes with the same infusion. Calendula is an excellent natural antiseptic, so traditional medicine strongly recommends calendula for cleansing the eyes. Cleansing the lens of the eye with a cataract: fir resin (a resinous substance released from tree trunks in places of damage) is instilled into the eyes, 1 drop at night. The burning sensation felt at the same time must be endured; Traditional medicine believes that oleoresin will resolve even an old thorn. Eye wash: used for conjunctivitis, pritis (inflammation of the iris), glaucoma. COLD WATER: Cold water has a beneficial effect on the organs of vision. You need to immerse your face in cold water 3-4 times for 3-4 seconds, or, taking water in your palms, throw it into your open eyes. Repeat this exercise several times. TEA LEAF: You can wash your eyes with tea leaves. It is better to use fresh tea leaves. You should wipe your eyes with a cotton swab soaked in tea leaves, from the outside of the eye to the inside. CUMIN BREW: Boil a tablespoon of caraway seeds in a glass of water and add 1 teaspoon of cornflower petals, 1 teaspoon of chopped eyebright herb and the same amount of chopped plantain leaves into the hot, unstrained broth. Leave for a day, then strain and carefully filter through cotton wool. Rinse eyes. Blinking: Frequent blinking helps to distribute tear fluid evenly and cleanse the eyeball. Sit down, close your eyes for 3-5 seconds, then open your eyes for the same period. Repeat 6-8 times. When the eyes blink, there is no need to rub them with your hands. Cleansing gymnastics for the eyes according to N. Semenova: central fixation consists of focusing the eyes on a special object, far or near, for about a minute. The eyes should be normally open, but not blinking. You have to watch it until the tears flow. The distance to the object is at least 48 cm, the posture is comfortable and relaxed. For example, you can fix your gaze on the top of a candle flame, on a small black circle pinned to the wall. The smaller the object to fix, the better. After several months of practicing central fixation of the eyes, you can move on to contemplating pure water. Pour water into a beautiful vase and contemplate for about 10 minutes the center of the reflection created by ordinary light. The vase must be positioned so that the focus of the reflection is in the center of the plate; you should contemplate this shiny surface. Central fixation on the water reflection, on top of the candle fire, is considered by the ancient science of yoga to be soothing for the eyes. A powerful subject of central fixation is the contemplation of various objects of Nature, such as water and sky. The order of central fixation with water-light contemplation in rooms with good lighting, with a painting or a reproduction of a good painting depicting the calm surface of water, goes back to more ancient traditions. Contemplation of the nose. Sitting relaxed, keep your neck straight and fixate the top of your nose with your eyes. Contemplate for 1-2 minutes, then close your eyes. Repeat 2-3 times. Close your eyes to rest. Contemplation of eyebrows. After a minute's rest with your eyes closed, fixate the point between your eyebrows with your eyes. Hold this for a minute or two. Close your eyes to rest. Contemplation of the right shoulder. Keep your body straight, neck and head firm. Fix your eyes at the end of your right shoulder. Stay like this for a minute or two. Close your eyes to rest. Breathing cleansing: take a deep breath, hold your breath. Bend at the waist and bow your head toward the ground, bending your knees so that your head is lower than your heart. Blood will flow to the head and eyes. The blood supplied with the oxygen you inhaled will wash away the poisons accumulated in the eyes. Remain in a bent position until count 5.

Contraindications

The operation is not possible if the following conditions and diseases are present:

• acute infectious and viral processes throughout the body or separately in the eyes;
• hepatitis, HIV infection;
• acute inflammation of any parts of the visual organs and surrounding skin surfaces;
• immune diseases in which tissue healing takes a long time (autoimmune condition, diabetes mellitus);
• corneal clouding;
• glaucoma – increased intraocular pressure;
• thinning of the cornea.

If the procedure is performed in the presence of contraindications, the patient's condition may worsen.

Why does she appear?

In the vast majority of cases, lens opacities are not associated with genetics. Only in the case of severe maternal illnesses, such as advanced diabetes mellitus, calcium deficiency, toxoplasmosis or rubella, do preconditions for the development of cataracts occur. In children, congenital cataracts often go away without surgical intervention, unless, of course, they occur against the background of another serious illness.

In other cases, the person becomes ill already in adulthood. Sometimes the cause of clouding is radiation, injury, metabolic failure, and sometimes age itself.

Stages of cataract development

So, the most common factors that provoke clouding of the lens are:

• age and associated metabolic disruptions;
• systematic doses of radiation or ultraviolet rays;
• injuries, deep wounds of the eye;
• contusions;
• glaucoma;
• severe diseases of autoimmune, endocrine or infectious origin - hypoparathyroidism, rheumatoid arthritis, diabetes;
• bad habits.

Symptoms of diabetes

Vitamin deficiency and the environmental situation in the area also negatively affect metabolic processes in the body and can act as provocateurs for the development of cataracts.

Patient reviews

Evgeniy, 65 years old: After I turned 60, I developed cataracts. She progressed quickly. The doctor advised to remove it and install an intraocular lens. That's what we did. After this, a secondary cataract formed. It was cleaned using a laser technique. Now I see well.

Olga, 61 years old: At the age of 50, I developed early cataracts. The doctor said it was due to metabolic disorders. The surgeon advised not to remove the lens, but to perform laser cleaning. My condition has improved significantly. Now I see well. But I was told that in the future it may be necessary to completely remove the lens.

Why does clouding of the artificial lens occur?

According to experts, the exact causes of complications after cataract removal have not yet been revealed. In general, this phenomenon can be explained by the growth of the epithelium and its localization on the surface of the dorsum of the capsule. As a result, its transparency is impaired, reducing visual acuity.

The epithelial cells that have turned into fibers are characterized by irregular shape and functional inferiority. Therefore, their movement to the center of the optical zone contributes to the occurrence of haze. However, this process is not a surgical error made during the operation.

Risk group

As a result of research, ophthalmologists have identified a number of factors that contribute to the occurrence of secondary cataracts after the lens has been replaced. These include the following:

1. Patient's age. Cataracts after surgery most often occur in childhood. This is due to the ability of young tissues to quickly regenerate, as a result of which epithelial cells begin to migrate and divide in the posterior capsule.
2. Shape of the intraocular lens. Square IOLs significantly reduce the risk of lesions.
3. The material from which the product is made. IOLs made on the basis of acrylic cause lens clouding much less frequently. The same cannot be said about silicone lenses.
4. The patient has diabetes mellitus and certain ophthalmological diseases.
