Keratoconus is a degenerative, non-inflammatory disease of the cornea. It is a progressive disorder in which thinning of the cornea is observed centrally or paracentrically, resulting in a conical shape. The disease usually manifests itself in adolescence and its progression is progressive until the third to fourth decade of life, followed by a slow progression. In 85% of cases, both eyes are affected, however the progression of the infection can be extremely asymmetric. The incidence of keratoconus in the general population ranges from 50-230 per 100,000 people. Keratoconus is considered a multifactorial disease with unclear etiology.
- Reduction of visual acuity
- Sudden increase in astigmatism
- Distorted vision at all distances
- Insufficient night vision
- One-eyed diplopia
The diagnosis of keratoconus is made by corneal topography (Pentacam – Placido).
- Collagen Interconnection – Cross Linking
- Intralayer rings – Kerarings
