CLINICAL OUTCOMES OF ACCELERATED EPITHELIUM-OFF CORNEAL COLLAGEN CROSS-LINKING FOR: A CASE OF ULTRATHIN POSTLASIK ECTATIC CORNEA

Abstract

29-year-old male with left eye diagnosed as post Lasik ectasia with extremely thin cornea after 3 years of uneventful Lasik surgery diagnosed by Scheimpflug based tomography device (Oculus Inc., Wetzlar, Germany), The uncorrected visual acuity (UCVA) in the left eye (LE) was 0.1 in decimal corrected to 0.4 by a refraction of -6.75Ds -4.5 0Dc @120, while the UCVA in the right eye (RE) was 1 in decimal without correction. Accelerated epithelium-off corneal cross-linking with pachymetric-guided corneal epithelial removal by (Avedro, USA) was done for the affected eye. The patient was followed up for one year with improvement of visual acuity as regards UCVA and BCVA and improvement of corneal topographic parameters including keratometry including mean K, K max and Belin ABCD keratoconus staging.
