PURPOSE To evaluate the clinical outcomes of wave front-guided (WFG) photorefractive keratectomy (PRK) using a high-definition aberrometer in corneas with keratoconus at least 1 year after corneal collagen cross-linking (CXL). METHODS Prospective uncontrolled interventional case series study including a total of 34 consecutive eyes of 25 patients with(More)
PURPOSE To evaluate and compare the visual and clinical outcomes of wavefront-guided laser in situ keratomileusis (LASIK) with the Alcon CustomCornea (Alcon Laboratories Inc, Fort Worth, Tex) and VISX CustomVue (VISX, Santa Clara, Calif) systems. METHODS Ninety-three eyes of 56 patients (50 and 43 consecutive eyes on CustomCornea and CustomVue,(More)
PURPOSE To investigate the predictability, safety, and efficiency of wavefront-guided laser in situ keratomileusis (LASIK) with iris-registration technology to correct mixed astigmatism. SETTING Vision correction center, Alexandria, Egypt. METHODS This retrospective double-blind study included randomly selected patients with mixed astigmatism who sought(More)
PURPOSE To compare higher-order aberration (HOA) measurements of LADARWave and Visx WaveScan aberrometers, to test the validity of the peripheral wavefront data, and to evaluate the effect of pharmacologic dilation and mild cycloplegia. METHODS Thirty-three myopic eyes of 17 volunteers were enrolled and had the ocular HOAs measured and analyzed with(More)
PURPOSE To evaluate in a pilot study the visual, refractive, corneal topographic, and aberrometric changes after wavefront-guided LASIK or photorefractive keratectomy (PRK) using a high-resolution aberrometer to calculate the treatment for aberrated eyes. METHODS Twenty aberrated eyes of 18 patients undergoing wavefront-guided LASIK or PRK using the VISX(More)
PURPOSE The aim of this study was to assess the predictability, efficacy, safety, and stability in patients who received a toric implantable collamer lens (TICL) after collagen crosslinking in early-stage keratoconus. METHODS This prospective interventional case series study was conducted at the Alexandria Main University hospitals, University of(More)
