Purpose: To analyze the efficacy of Corneal Collagen Crosslinking with Riboflavin and Ultraviolet- A in progressive Keratoconus.
Materials and Methods: Nonrandomized, interventional, retrospective prospective study of 53 eyes of 4 patients with progressive Keratoconus. The study was conducted from May 2011 to May 2017. Inclusion Criteria were documented progression of keratoconus by refraction, keratometry or topography with pachymetry more than 400 microns and age less than 35 years. Crosslinking was performed using Riboflavin 0.1% and ultraviolet-A light of 370nm using a3mW/cm2 irradiance after removing the central 7mm of the corneal epithelium using a blunt knife. A bandage contact lens was fitted until reepithelialisation.
Results: Improvement in BCVA at the end of 1yaer was seen in 45.27%, BCVA worsened in 16.98% and BCVA remained stable in 37.73%. Max keratometric value found to be stable in 77.35%, showed regression in 16.98% and progression in 5.66%.
