Thanks to the cornea, the image clearly focuses on the retina, which allows a person to see. Lumbling or changing the spherical structure (keratoconus) leads to a violation of vision. In fact, this disease is the thinning of the cornea epithelium, which changes the form under the influence of eye pressure. In many cases, the only way out is the complete replacement of the shell on the donor, that is, transplantation.
The main indication for the use of surgery is heavy conditions (eg clouding, ulcers, injuries, inflammation, existence, (cornea disorders), against which the optical (visual) corneal functions are deeply disturbed, without the possibility of correction), when it is no longer possible to preserve the patient’s own cornea with other treatment methods, and the only way out is a partial or complete replacement of the horny shell of the eye to the donor, that is, transplantation.
