Abstract

Purpose: To evaluate the visual and clinical outcomes of simultaneous topography-guided photorefractive keratectomy (PRK) and corneal collagen crosslinking (CXL) in keratoconus.

Methods: A prospective interventional study that enrolled 30 patients with keratoconus (30 eyes). All patients underwent customized topography-guided PRK followed by CXL. Uncorrected (UCVA) and best corrected (BCVA) distance visual acuities, flat and steep keratometry (K1 and K2) readings were evaluated postoperatively.

Results: At 1 year, mean UCVA improved to 0.51 logMAR from 0.84 and BCVA improved from 0.42 logMAR to 0.23 (P<0.05). The mean K1 and K2 readings were reduced by 1.7 diopters (D) and 2.18 D respectively and Kmax flattened from 57.01 D to 52.74 D (P<0.05). Conclusion: Simultaneous topography-guided PRK and CXL was a safe and effective surgical alternative for keratoconus. This combined treatment is capable of offering patients functional vision and stabilization of the ectatic disorder.
