CLINICAL STUDY, ONE YEAR AFTER THE CORNEAL COLLAGEN CROSS-LINKING PERFORMED FOR THE PATIENTS WITH KERATOCONUS
Abstract:
The aim of this work is to present retrospective
results obtained after corneal collagen cross-linking
procedure for the patients with progressive keratoconus.
Materials: This study included patients with progressive
keratoconus in stage II and III, aged between 16 and 44
years old. Methods: The therapeutic procedure has been
applied to 49 patients (71 eyes); corrected and
uncorrected visual acuity, corneal thickness values and
topographic aspects were recorded before and after
surgery at 1, 3, 6 and 12 months. Results: Visual acuity
remained unchanged for the majority of cases, and for 36
cases it improved with 1-4 Snellen lines. The average
increase of the corneal thickness was 10.01 ± 7.03
microns. The average reduction of the maximum
keratometric readings was 1.20 ± 1.05 dioptres.
Conclusions: Stabile visual acuity, the increase of the
corneal thickness and the decrease of the maximum
keratometric readings show that this technique represents
a method to stop the progression of keratoconus.
