Corneal collagen cross-linking in keratoconus -- long-term prospective study

Abstract

Purpose: To determine the refractometric, keratometric and functional results 3 years after cross-linking therapy in patients with keratoconus.

Patients and methods: Eighty-one patients in various stages of keratoconus were studied, all meeting eligibility criteria for the cross-linking technique.

Results: The results showed a decrease both in the K-values, of about 1.5 D, and in the refraction. Visual acuity improved by 1, 2 or 3 Snellen lines in 70% of the cases.

Conclusions: The cross-linking technique is a modern method for stopping the progression of keratoconus.
