Abstract

Keratoconus is one of the leading causes of corneal blindness and a frequent indication for penetrating keratoplasty (PK) (1). One of the most effective methods for visual rehabilitation of keratoconus patients is rigid contact lenses use, but a high percent of these patients are contact lens intolerant. Various types of surgical procedures have been suggested for keratoconus as an alternative for PK, including apex cauterization, epikeratophakia, sectorial keratotomy, photorefractive keratotomy (PRK), Lasik, and lamellar keratoplasty, but with worse results when compared to PK (2).
