Abstract

Purpose: To report the long-term results of combined topography-guided PRK and CXL for keratoconus

Methods: Patients underwent customized topography-guided PRK followed by CXL. UDVA, CDVA, keratometry readings and complications were evaluated at 1,3, 6, 12 and 24 months postoperatively.

Results:30 patients (30 eyes) were included in the study. At 24 months, the mean UDVA improved from 0.8 ± 0.180 to 0.38 ± 0.118 logMAR (P value<0.001) and CDVA improved from 0.467 ± 0.142 to 0.227 ± 0.078 logMAR (P value< 0.001). The mean flat, steep and maximum keratometry values were significantly reduced by 2.133, 3 and 4.54 diopters respectively, at the last follow up examination (P value<0.001). Conclusion: The combined topography-guided PRK and CXL procedure seems to be a promising treatment for early keratoconus. However, further studies with larger study population and longer follow up periods are required to draw final conclusions about the benefits of this procedure in keratoconus.
