Treatment and prevention

Treatment generally the surgical. To an arrest of development of a senile cataract apply medicines – вицеин, витайодурол, витафакол, катапин ?, katakhry.

The forecast at the acquired cataracts and safety of function of the neuroreceptor device the favorable. The stationary cataracts which significantly aren't influencing visual acuity, don't demand treatment. The visual outcome at a congenital cataract which is usually combined with changes in the neuroreceptor device, is much worse, than at the acquired cataract.

Cataract prevention by antioxidants

It is considered that many of the risk factors connected with a cataract, are explained by the oxidizing stress occurring in a crystalline lens of an eye. Structures of an eye are very active and as a result of an intensive metabolism in them a large number of free radicals is released. These free radicals can become the potential reason of damage of the eye structures creating conditions for development of a cataract. In a healthy organism there are enough antioxidants for "cleaning" of free radicals and protection of eyes against their destructive influence.

Nevertheless, strengthening of an oxidizing stress in an organism (as a result of smoking or bad food) can overcome the systems responsible for a utilzation of free radicals therefore eyes suffer from damages more often. That is why one of the most approaches well studied in the nature on prevention of a cataract is antioxidant therapy.

Glutathione

Glutathione is the most powerful antioxidant of an organism. The high contents it is revealed in an eye and structures surrounding it. Certain whites of the eye are considered especially sensitive to destructive influence of free radicals. Damages of these proteinaceous structures can lead to changes in the eye, being the reason of cataract. It is interesting that these negative changes, seemingly, happen only at considerable falling of level of glutathione.

Purposeful increase of level of glutathione can represent a complex challenge because it isn't absorbed in the form of additives. Researches nevertheless show that the increase in level of other nutrients can raise the content of glutathione in eyes.

Vitamin E

Some researches in public showed that low consumption levels of vitamin E are connected with the increased risk of development of a cataract. Research under the name Vitamin E and Cataract Prevention (Vitamin E and Cataract Prevention Study (VECAT) observing 35,000 women of middle age within 10 years, led to interesting opening about communication of vitamin E and health of eyes. This research found out that women with a high consumption level of vitamin E, and also vitamin C and beta carotene showed much lower risk of development of a cataract in comparison with women with a lack of these нутриентов. The women receiving the greatest numbers of these antioxidants, were 18% less subject to risk of development of a cataract.

Results of other researches with vitamin E appeared not less impressive. 1,380 participants of Research of Cataract aged from 40 till 79 years were estimated by the Sluchay-Kontrol method on level of the content of vitamin E and mineral substance of selenium at blood. The risk of development of a cataract was considerably reduced at participants with the high content of vitamin E. Selenium plays a key role in synthesis of glutathione and can be an important component of the program for cataract prevention.

Lyutein and Zeaksantin

Lyutein and зеаксантин treat the family of carotinoids connected also with vitamin A. They possess very specific affinity to structures of an eye both in a crystalline lens and in a retina are in higher concentration, than in any other part of a body.

Prospektivny research – part of Research of Health of Nurses, - observed 77,466 nurses aged from 45 till 71 years for the purpose of definition of effects of vitamin A and каротинов on risk of emergence of a cataract. They found out that the risk of need of operation on removal of a cataract was 22% lower among the women using the greatest numbers лютеина and зеаксантина in the diet in comparison with participants, consuming the minimum quantities of these нутриентов. Food sources лютеина and зеаксантина include eggs, cabbage, spinach, a turnip, sheet cabbage, salad a romaine, broccoli, pumpkin, corn, peas and Brussels sprout.

Lyutein and зеаксантин are useful not only for cataract prevention – they also provide essential advantage in treatment and prevention of a degeneration of a yellow spot, one more serious disease affecting eyes at aging.

Cataract prevention by medical foods

Some epidemiological researches showed communication between a choice of a diet and risk of development of a cataract. The most useful product is, seemingly, spinach – as it is shown steadily by the researches correlating food with decrease in risk of a cataract. To other, not less useful products, krestotsvetny vegetables (especially cabbage and broccoli), tomatoes, pepper, a citrus and melons belong. The greatest risk connect with such food, as butter, vegetable oils (except olive oil), salt and with the increased consumption of fats generally.
