KERATOCONUS

What is;

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.

Symptoms:

  • Reduction of visual acuity
  • Sudden increase in astigmatism
  • Distorted vision at all distances
  • Insufficient night vision
  • One-eyed diplopia

Diagnosis:

The diagnosis of keratoconus is made by corneal topography (Pentacam – Placido).

Treatment Methods:

  • Collagen Interconnection – Cross Linking
  • Intralayer rings – Kerarings
  • Special keratoconus contact lenses
  • PRK-CXL
