Cataracts have recently become rapidly younger and affects even babies. However, don't panic. Modern medicine is already able to cope with this ailment. The main thing is to identify deviations in time and seek help.

Cataract

A person has two eyes. Each of them consists of a tunica albuginea and an iris. The tunica albuginea covers the top of the eyeball. The iris of each person has a certain color, and the pupil is located in its center. In fact, the pupil is an opening, which, by analogy with the aperture of a camera, depending on the illumination, lets a certain amount of light into the eyeball. Inside, at some distance from the pupil, there is a lens. It is able to change its optical properties due to its curvature. The light passing through it is projected onto the retina, and the person sees the image.

Cataract is a disease in which the lens is no longer transparent and elastic. It changes its curvature worse, which means its optical properties are reduced. Light passing through such a lens is scattered, and the image is indistinct.

Anyone can make a diagnosis. It is enough for him to look into the eyes. The clouded lens gives itself out in gray instead of a black pupil. The disease affects at any age, but more often people who have crossed the threshold of fifty years become patients of ophthalmologists.

Cataracts have one characteristic symptom that you can check yourself. Such patients see better in the dark. With cataracts, the central part of the lens is affected. During the daytime, the pupil constricts, limiting the flow of light. It hits the affected part of the lens, and the patient sees a blurry picture. In the evening, in low light conditions, the pupil dilates, allowing more light to pass through. The beam of light becomes larger and hits the healthy areas of the lens, which makes vision clearer.

The person is very gullible. He believes in television advertisements that promise to cure cataracts if he takes drugs with a high content of carrots or blueberries and drops special drops into his eyes. Unfortunately, there are no drugs that can help with glaucoma. There is only one option to get rid of this ailment - surgery. It consists in replacing the natural clouded lens with an artificial one.

The duration of the operation is no more than twenty minutes. The whole process is monitored with a microscope. The patient is under anesthesia and does not feel anything. The surgeon penetrates under the cornea and removes the clouded lens, and puts an artificial lens in its place (its size is about 1 cm).

If the patient wishes to correct his vision, which suffered before the operation, a lens with diopters can be ordered. Then, after treatment, he may not wear glasses. Immediately after the operation, patients begin to see clearly. Clarity of vision returns to them, as if a veil has been removed from their eyes. The time has come when it is already possible to help such patients. Unfortunately, so far there are not many places where such operations are performed. This assistance is not included in the list of compulsory medical insurance, and its cost is quite high.
