WHAT IS KERATOCONUS?
Keratoconus is a disease of the cornea that causes progressive degeneration and usually occurs in both eyes at the same time. During this evolution, the cornea adopts an irregular conical shape due to the internal alteration of the corneal tissue that is manifested in the thinning of the corneal structure in its central or paracentral zone. High irregular astigmatism may also occur.
At present, the specific cause of corneal changes has not been specified, although in many cases there are antecedents in the patient’s family.
The first symptoms of keratoconus usually appear during puberty or early adolescence, progressing up to 30 or 40 years, when evolution usually stops, although the disease may become stationary at any time.
Sometimes, the pathology appears in more advanced ages and, in this case, does not degenerate as much as the astigmatism that is usually associated with keratoconus is lower than in the case of the early ages.
