BACKGROUND The aim of this study is to evaluate the safety and effectiveness of riboflavin-ultraviolet type A (UV-A) light rays induced cross-linking of corneal collagen in improving visual acuity and in stabilizing the progression of keratoconic eyes. The method of corneal cross-linking using riboflavin and UV-A light is technically simple and less(More)
PURPOSE To evaluate the postoperative clinical outcomes and higher-order aberrations (HOAs) in eyes with astigmatism greater than 2.00 diopters (D) that had laser in situ keratomileusis (LASIK) using a non-wavefront-guided aberration-free ablation profile. SETTINGS Private practice. METHODS This retrospective study evaluated the 6-month results of LASIK(More)
PURPOSE To compare the clinical outcomes of aberration-free ablation profiles based on the normal corneal vertex (CV) and the pupil center (PC) in relation to laser in situ keratomileusis. Aberration-free aspheric ablation treatments were performed in all cases. METHODS Two myopic astigmatism groups (CV centered using the offset between pupil center and(More)
PURPOSE To evaluate the clinical outcomes of aspheric corneal wavefront (CW) ablation profiles in LASIK treatments. METHODS Thirty eyes treated with CW ablation profiles were included after a follow-up of 6 months. In all cases, standard examinations including preoperative and postoperative wavefront analysis with a CW topographer (Optikon Keratron Scout)(More)
PURPOSE To compare measurements of ultrasound, Scheimpflug, and optical coherence pachymetric techniques to describe ablated depth after myopic astigmatic corneal laser refractive surgery and achieved refractive correction. METHODS Ninety-six myopic astigmatism treatments using LASIK or LASEK in 58 patients with 3-month followup were retrospectively(More)
PURPOSE to compare visual, refractive, and wavefront aberration outcomes of laser epithelial keratomileusis (LASEK), thin-flap LASIK (flap thickness 110 to 130 microm), and ultrathin-flap LASIK (flap thickness <110 microm) after excimer laser ablation with an aspheric ablation profile. METHODS a retrospective analysis of 97 eyes of 56 patients with myopia(More)
PURPOSE To evaluate the clinical outcomes of LASIK using optimized "aberration neutral" ablation profiles. METHODS Laser in situ keratomileusis was performed in 231 eyes (120 patients) with a mean spherical equivalent refraction of -4.12+/-2.26 diopters (D) (range: -0.37 to -9.50 D) using a SCHWIND Pendular microkeratome with a 130-microm cutting head and(More)
PURPOSE To evaluate the clinical outcomes of aspheric ocular wavefront ablation profiles in LASIK treatments. METHODS Thirty eyes treated by ocular wavefront were retrospectively analyzed at 6-month follow-up. Custom Ablation Manager (CAM) software was used to plan wavefront-customized aspheric treatments, and the ESIRIS system was used to perform(More)
