Hypermetropic astigmatism

Hypermethropic astigmatism is one of the deviations of vision with farsightedness. In most cases, it flows imperceptibly for the wearer, but sometimes it can cause increased irritability and headache. Hypermethropic astigmatism of both eyes practically does not occur, usually the disease develops only on one eye.

The provoking factors of astigmatism

Astigmatism is a visual impairment in which different degrees of nearsightedness and farsightedness develop on different meridians of the eyeball, as a result, the eye focuses on two points, from which it becomes tired and the vision begins to decrease more strongly. Astigmatism in hypermetropia, that is, farsightedness, can be congenital, and in this case gradually vision normalizes, and can be caused by various kinds of trauma. Here are the main types of illness:

• simple hypermetropic astigmatism;
• complex hypermetropic astigmatism;
• complex direct hypermetropic astigmatism.

With simple astigmatism in one of the meridians of the eye, hyperopia develops, while in the other, vision is maintained at the level of "one", normal. At a complex on both meridians the farsightedness is fixed. In the first case, the clearness of vision can not be reduced for years and the disease is detected by chance. The most common symptom is severe headaches of unknown origin.

In the second case, visual defects are noticeable to the patient at once, and often hypermetropic astigmatism is accompanied by amblyopia. This so-called "lazy eye" syndrome, when optical devices do not affect visual acuity, neither glasses nor lenses improve the situation. Here are the main reasons for this painful condition:

• congenital difference in eye refractivity;
• visual deprivation of one of the eyes;
• strabismus ;
• hysteria and nervous disorders of all kinds;
• violation of refraction.

Is it possible to cure complex direct hypermetropic astigmatism?

Simple astigmatism in treatment and correction does not need, with complex forms it is recommended to wear glasses in order to give eyes necessary leisure. With the help of lenses and glasses, the corrective effect on the problem can not be rendered, the only effective method to cure complex astigmatism is surgery today. Here are the most popular of them:

• laser thermokeratoplasty;
• thermokeratocoagulation;
• hypermetropic laser keratomileusis.

As an auxiliary technique, a hardware treatment can be prescribed.
