Abstract

Purpose: To evaluate outcomes of TG-PRK with CXL in patients with k-conus with MEL 90 excimer laser system. Methods: In this retrospective study, 70 eyes of 38 patients with early k-conus with adequate pachy(≥ 450), SE ≤ 4 D were selected for TG-PRK with CXL. Analysis was done at the end of 1 year. Results: At 1 year, mean BCVA reduced from 0.25± 0.26 to 0.1 ± 0.07 (p <0.05). Mean SE(D) and cylinder(D) reduced from -1.70 ±1.33 to -0.96 ±1.15 (p <0.05) and -1.90±1.28 to -1.35±1.2 (p <0.05) respectively. There was a change in mean thinnest pachy, K1, K2, K mean(D) from 493.09± 38.27, 44.39±2.28, 46.84± 2.53, 45.62±2.18 to 420.92±62.25(p <0.05), 43.18±2.36, 45.44±2.71, 44.27±2.46 respectively. HOA reduced from 1.39±0.78 to 1.16±0.89(RMS). Mean demarcation line depth on AS-OCT was 212±15 microns. None had haze at 1 year. Conclusion: TG-PRK with accelerated CXL performed with MEL 90 was safe and effective in management of early k-conus and provided satisfactory visual outcomes.
