Abstract Details



Purpose:

The aim of this study was to report the outcomes of corneal collagen crosslinking (CXL) after previous radial keratotomy (RK) in keratoconus patients

Setting:

Beyoglu Eye Research and Educaty ion Hospital

Methods:

İn this study, single-centre case series involving 8 eyes of 6 keratoconus patients with RK who had undergone CXL were reviewed retrospectively. Visual acuity, manifest refraction, and corneal topography were recorded preoperatively and at 1,6 and 12 months after the procedure.

Results:

Eight eyes of 6 keratoconus patients that had undergone an RK 8 to 13 years before the CXL were included in the study. The mean uncorrected distance visual acuity pre and 12 months after the CXL were 0.18 logMAR and 0.12 logMAR (P = 0.5), respectively. The mean average keratometry pre and 12 months after the CXL were 46.5 and 45.8 diopters (P = 0.06), respectively. The mean corneal astigmatism values pre and 12 months after the CXL were 4,8 and 4.6 diopters (P = 0.06), respectively. The mean manifest refraction spherical equivalents (MRSEs) before and 12 months after the CXL were -4.4 and -3.8 (P = 0.06), respectively.

Conclusions:

CXL is a safe and effective method to restore corneal stability in keratoconus eyes with a history of RK. Therefore, a longer follow-up is necessary to validate these findings. FINANCIAL INTEREST: NONE
