Abstract
Purpose: To evaluate the outcome of same day topographic-guided photorefractive keratomileusis (PRK) and corneal cross-linkage in patients with subclinical keratoconus. Materials and Methods: A total of 20 patients with subclinical keratoconus were treated with topographic-guided PRK and same day corneal collagen cross-linkage with riboflavin. Inclusion criteria was low grade myopia of up to 3 diopter spherical equivalent, corneal thickness more than 475 microns, maximum keratometry reading K max less than 50 D. Results: Median preoperative spherical equivalent refraction was −2.25 D. At final follow-up visit at 1 year spherical equivalent was statistically significantly reduced to −0.25 D ( P Conclusion: Same day topographic-guided PRK and corneal cross-linkage is a safe treatment offering good vision in subclinical cases of keratoconus.
