Wavefront aberration outcomes of LASIK for high myopia and high hyperopia.
PURPOSE To determine the higher order aberrations at the corneal first surface after conventional LASIK for high myopia and high hyperopia. METHODS This was a retrospective study using a convenience sample with subjects divided into five groups by level of refractive correction. Group 1 were normals, having no eye disease or previous surgery, but may have had refractive error. Group 2 had low...
متن کاملThe Changes of Posterior Corneal Surface and High-Order Aberrations after Refractive Surgery in Moderate Myopia
PURPOSE To compare forward shift of posterior corneal surface and higher-order aberration (HOA) changes after LASIK, LASEK, and wavefront-guided LASEK surgery in moderate myopia METHODS One hundred eighty four eyes undergoing LASIK, LASEK and wavefront-guided LASEK with VISX STAR S4 were included in this study. The posterior corneal elevation was measured with Orbscan before, 2 and 4 months a...
متن کاملEffects of optimized photorefractive keratectomy (PRK) operation on the asphericity and high-order aberration changes
Background: Optimized is a common and important method in which aberrations are created by the device and the surgeon, but high-grade aberrations are out of the surgeon's control and are induced by the device in the patient. The aim of this study was the evaluation of out-of-control high-order aberration changes before and after PRK surgery and these impact on vision outcome. Materials and meth...
متن کاملComparison of ocular higher-order aberrations after SMILE and Wavefront-guided Femtosecond LASIK for myopia
BACKGROUND To compare changes in higher-order aberrations (HOAs) following small incision lenticule extraction (SMILE) and wavefront-guided femtosecond laser-assisted in situ keratomileusis (WFG FS-LASIK), and to investigate correlations between preoperative spherical equivalence (SE) and components of HOAs affecting visual quality. METHODS Sixty-five myopic eyes from 38 patients were enrolle...
متن کاملOne year refractive outcomes of Femtosecond-LASIK in mild, moderate and high myopia
Purpose: To evaluate the safety, efficacy, predictability and stability for a cohort of myopic eyes treated by Femtosecond-LASIK procedure. Methods: 60 eyes (36 patients) with different degrees of myopia that underwent refractive surgery by using the Femtosecond-LASIK technique were prospectively evaluated for 12 months. The mean preoperative spherical equivalent value was -3.827 ± 1.410 diopte...
