IT specialist's vision: what you personally need to know

Клиника офтальмологии доктора Шиловой corporate blog Biotechnologies Health
Translation


— Which is better: glasses, lenses or laser vision correction?
It is best to see without any means of correction. If you are completely satisfied with the glasses — keep calm, no other correction is needed. Lenses — this method of correction requires adherence to clear rules of use, which is ultimately more costly and risky, but it is very popular because the main dangers do not appear immediately after the start of wearing, but years later.

— I decided to stay on the glasses, but I am afraid that the car's pillow will open in my face and they will become contact lenses. What to do?
In my surgical experience, modern airbags do not injure eyeglasses. Eyes and face are usually damaged by windshield fragments. If you are concerned about the safety of glasses, then think about the modern, with polycarbonate lenses, they are incredibly durable, the car drives on crash tests.

— Is it true that all eye disease from the computer?
No, it's not true. The main cause of problems with optics — myopia, hyperopia or astigmatism — is genetics. Adverse environmental conditions, especially during long-term work at close range, are important in childhood, when the development of the organism is not yet complete. And such diseases as cataract, glaucoma, retinal detachment and other diseases occur with the same frequency in those who work at the computer for hours and in those who do not know where the computer has a power button.

Cataract: it is waiting for you personally (if you live, of course)

Клиника офтальмологии доктора Шиловой corporate blog Biotechnologies Health
Translation

This is a model of an intraocular multifocal lens from Carl Zeiss. The real size of such a lens is 11 millimeters, the diameter of the optical zone is 6 mm.

The cataract is, simplifying, age opacification and consolidation of a crystalline lens. According to the classical definition, we are talking about the turbidity of any type. First, something gets in the field of view, a general “fog” appears, you want to wipe dirty glasses, then you do not see the letters in the book, then you want to turn on the light brighter or, on the contrary, you hide from the bright light, and then wake up one fine morning and understand that you can not find slippers. And you see nothing at all — only the shadows. This process sometimes stretches for many years, but slippers are still lost. Mention of clouding that develops in the eyeball, there are still thousands of years before our era.

The treatment procedure has historically been very peculiar — reclination of a cloudy lens. The doctor took the patient with a very dense lens — to that dense stage that the patient is already blind. During the excavations of the settlements of ancient Greece and Rome, the tools used by doctors to remove cataracts were found — sharp needles that pierced the eye and lens, destroying its supporting apparatus. The lens could come off and, by virtue of its gravity, could also fall down from hitting the back of the head with a heavy stick several times. Sometimes the patient died during the emergency eye care, sometimes he had a concussion, and sometimes the lens fell off the ligaments and flew deep into the eye. The patient began to see again — he had a huge lump and vision of about +10 +15 diopters.

Now two news. The bad — people began to live to cataracts more often, and it is inevitable. Good — we have something better than sharp needles and a heavy stick.

Presbyopia: «menopause» of the eyes in men and women

Клиника офтальмологии доктора Шиловой corporate blog Biotechnologies Health
Translation

What do you think, how many operations can be done on one eye? A clinical case of one of my patients confirms that more than 20 operations of various kinds are not the limit. Although, no doubt, this case is a record for Russia and the world of ophthalmology.

In 1978, everything was trivial — there was an 18 year old boy (let's call him “A”) who wanted to become a test pilot like his father. This was hampered by weak myopia of the right eye — only minus 1, it did not interfere with life, but the future pilot needed good vision. He decided to correct the optics of one eye by keratotomy — the old “manual” correction method at the Fedorov Institute (of course, through an acquaintance), but something went wrong. This was the first operation. Then four more in Russia, then seven more — in Switzerland. He did not become a pilot, but he became an oligarch, a man who manages serious business projects, but does not control the situation with his vision.

To me, «A» got completely disappointed in the world of ophthalmology, with 10% vision, the impossibility of correction by standard methods and high intraocular pressure. And it was a young 50-year-old businessman, successful in life (this is important — because not everything went further «like that» either). So — the next eight operations are mine. And although we expected that one or two would be enough — we had to go through almost total ophthalmic surgery — all possible types of operations.

By the way, instead of keratotomy, there would be a correction of SMILE (ReLEX SMILE) or, at least, Femto-LASIK — there wouldn’t be anything to write about — it’s impossible to do anything like that!

Glaucoma — not heard of it? Meet the serial silent view killer

Клиника офтальмологии доктора Шиловой corporate blog Biotechnologies Health
Translation
Among the eye diseases are those that are especially dangerous. At first they are asymptomatic — nothing hurts, there are no complaints, they can “disguise” as other “mild” diseases and, most importantly, appear at any age and irrevocably “destroy” their eyesight.

Imagine if you left your left eye accidentally, but with your right, everything is “like a fog”! Read on the Internet how to help yourself or call your friends, and they — do not worry, blink. While they were waiting, it seemed that the fog was really over. This is how periods of anxiety recur, but at first there is little concern. And he (the murderer) began his insidious business. And as a rule, in both eyes, even if the second does not bother! And age is not an obstacle — children are also susceptible to this disease — 10% of children are blind from glaucoma.

Glaucoma is quite common in all countries — in 15% of cases of blindness, it is she who is the cause. This puts her in second place to the causes of incurable blindness!

And all is why — because the human brain very well «replaces» the dips in the field of view, if they arise gradually, adapt, and only when 30-40% of the optic nerve the feeling of «fog» begins. And all — hello, lost non-renewable!

Glaucoma — how not to go blind: let's talk about the treatment…

Клиника офтальмологии доктора Шиловой corporate blog Biotechnologies Health
Translation
We know that nobody is immune to glaucoma.

The number of patients with glaucoma worldwide more than 100 million (!) People. Nine out of ten blind people live in developing countries, and two thirds of them could be cured, they begin to be treated on time.

Glaucoma is the second cause of blindness after cataract — up to 20% of all cases of the disease end with it. Some people do not know about the disease. Glaucoma is often detected at stage 2–3 or at the last, 4th stage, when it is often impossible to help a person. In Russia, glaucoma has recently become the first cause of irreversible blindness, overtaking injury and vascular eye disease.

Despite a serious breakthrough in the understanding of many of the problems of glaucoma over the past few years, it must be admitted that so far no effective methods have been proposed to prevent the disease, its early (fairly cheap method!) Identification and treatment methods that are widely available.

The trouble is that the prevention of this disease, we have long ceased. Previously, after forty, all Soviet people were sure to measure eye pressure once a year. In clinics there were professional examination rooms, people with elevated intraocular pressure were referred to an ophthalmologist. And so revealed about half of patients with glaucoma. Now there is nothing like this. Saving patients was the work of the patients themselves (that is, drowning people).

лечение глаукомы

Since the treatment of glaucoma is just as dangerous as caving — you climb into the dark, and when and what falls on your head, science is unknown. But if you don’t fall, you will drown or suffocate yourself — there are options. When you guess where you are, it will be too late. Let me start with a number of rules described below.

Astigmatism — vision as in the kingdom of «crooked mirrors»

Клиника офтальмологии доктора Шиловой corporate blog Biotechnologies Health
Translation
Friends, after a break, we resume publications on vision and technology to restore it. The pause was connected with my workload of operations and participation in conferences: in the near future I will publish a review of the most interesting technical innovations in ophthalmology that were presented at them, and today we will talk about astigmatism.

Что такое астигматизм

Modern statistics depressing. More than half of the world's population suffers from visual impairment, the most common problems are myopia and hyperopia. But ophthalmologists often diagnose another disease, the name of which is unfamiliar to many. Astigmatism is a defect in the optical system of the eye when the sharpness of the image is asymmetric vertically and horizontally. And the parallel rays of light passing through the eye are focused not into a point, but into the “eight”. For a person, this means that the visibility of the image becomes unsharp, and this often applies to both distant and close objects. As a result, instead of a normal image, a person sees a distorted image, in which some lines are clear, others are blurred. An idea of ​​this can be obtained if you look at your distorted reflection in an oval teaspoon.

Ophthalmologists say that almost two thirds of the world's inhabitants face such a problem. But since the degree of astigmatism may be small, many people practically do not feel any discomfort. It is difficult for doctors to identify a clear list of common symptoms indicating that a patient has astigmatism. In each case, they will differ. In the very early stages, it is often confused with tired eyes.

However, quite a few people need special treatment or correction of this disorder with the help of glasses, contact lenses or even surgery.

How to “sew up” the retina and should it be done?

Клиника офтальмологии доктора Шиловой corporate blog Biotechnologies Lazers Health
Translation
Imagine the situation — you live in peace, nothing hurts and does not blush, wear glasses or lenses, or do not use anything and see perfectly — and you accidentally get an appointment with an ophthalmologist. For example, because of conscription into the army, because of pregnancy, or just for a dispensary examination. And suddenly you will find out that your retina is “full of holes” or stretched and is about to break.

And they recommend you to “sew it on”. And you doubt — and this is exactly what you need? And how safe is it? But nothing bothers — then why? Or maybe they want to earn money on me? And the first thing you start is to read posts on the Internet, what a “independent” expert like Google will say.

And in the future everything depends on your discipline and attention to your own health. You can get to the ophthalmologist-laser specialist, who will be the last resort, and he will do preventive laser coagulation.

Or «forget it» for everything and continue to live as before — nothing bothers you. What is the risk?

Retinal detachment — what is important to know about it

Клиника офтальмологии доктора Шиловой corporate blog Biotechnologies Health
Translation
Retinal detachment is a formidable eye disease that, without surgical treatment, most often results in complete loss of vision.

The human eye can be compared with the device of the camera, the lens of which is the cornea with the lens, and the film is the retina, an extremely complex multi-layer structure that is connected to the visual divisions of the brain with the help of nerve fibers. Therefore, we can assume that the retina is a part of the brain.

Retinal detachment most often takes the patient by surprise — before it appears, a person may have excellent vision and may not present any complaints. The speed of propagation of the process is quite rapid, the treatment in the majority of cases is surgical.


The timeliness of the operation gives a chance to preserve vision; in Germany, according to the standard, the operation must be performed within 24 hours after the diagnosis. There are no such standards in Russia. But for each patient, I say that retinal detachment is “like fresh frozen fish” — in a couple of days it’s already “not the first freshness”.
