Abstract

Aim: To report the long-term results of combined T-PRK & CXL for KC
Methods: Patients with mild to moderate progressive keratoconus & corneal pachymetry greater than 450µm were included. They underwent customized T-PRK followed by CXL. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), keratometry readings and complications were evaluated at 1,3, 6, 12, 24 & 36 months postop.
Results:30 eyes were included. All study parameters showed a statistically significant improvement postoperatively over baseline values. At 24 months, the mean UDVA improved from 0.8 ± 0.180 logMAR to 0.38 ± 0.118 logMAR (P value<0.001) and CDVA improved from 0.467 ± 0.142 logMAR 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 (P value<0.001).
Conclusion: Combined T-PRK & CXL procedure seems to be a promising treatment alternative for KC.
