corneal biomechanics

Corneal cross-linking (CXL) with ultraviolet-A (UVA) and riboflavin has been used increasingly during past decades. There is strong evidence of its effect on stabilizing the biomechanics of the cornea, so it has become the gold standard for treatment for slowing the progression of keratoconus and post–laser-assisted in situ keratomileusis (LASIK) corneal ectasia. Riboflavin serves as a photosen...

Purpose The purpose of this study was to determine the effect of flap thickness on corneal biomechanics after myopic laser in situ keratomileusis (LASIK). Methods This is a prospective controlled non-randomized, institutional study. Patients underwent either epi-LASIK with mitomycin (advanced surface ablation [ASA]), thin-flap LASIK (90 µm head), or thick-flap LASIK (130 µm head). In ASA, the...
