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...

OBJECTIVE To study the correlation and effect of sequential measurement of intraocular pressure (IOP) with Goldmann applanation tonometer (GAT), ocular response analyzer (ORA), dynamic contour tonometer (DCT), and Corvis ST. SETTING AND DESIGN Observational cross-sectional series from the comprehensive clinic of a tertiary eye care center seen during December 2012. METHODS One hundred and t...

The effect of flap thickness on corneal biomechanics after myopic laser in situ keratomileusis using the M-2 microkeratome

2017

Iyad A Goussous Mohamed-Sameh El-Agha Ahmed Awadein Mohamed H Hosny Alaa A Ghaith Ahmed L Khattab

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...
