Evaluation of corneal higher order aberrations in normal topographic patterns
PURPOSE This study reports the characteristics of corneal higher order aberrations (HOAs) in eyes with normal topographic pattern using the Pentacam scheimpflug system. METHODS In this prospective, observational, comparative study, 165 eyes of 97 patients separated into five groups based on corneal topographic patterns were enrolled. All eyes received a comprehensive ophthalmologic examinatio...
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 کاملHigher-order aberrations after corneal collagen crosslinking for keratoconus and corneal ectasia.
PURPOSE To determine changes in higher-order aberrations (HOAs) after corneal collagen crosslinking (CXL). SETTING Cornea and refractive surgery practice. DESIGN Prospective randomized controlled clinical trial. METHODS Corneal and ocular HOAs were measured and analyzed using the Pentacam device and Ladarwave aberrometer, respectively, at baseline and 12 months after CXL. RESULTS Ninety...
متن کاملCorrelation between Corneal Topographic Indices and Higher-Order Aberrations in Keratoconus
PURPOSE To compare corneal higher-order aberrations (HOAs) between normal and keratoconic eyes, and to investigate the association between elevation-based corneal topographic indices and corneal wavefront data in the latter group. METHODS In this cross-sectional comparative study, 77 normal right eyes of 77 control subjects and 66 eyes of 36 keratoconic patients were included. In each eye, el...
متن کاملcorrelation between refractive, corneal and lenticular astigmatisms and higher order aberrations in refractive surgery candidates
purpose: to evaluate the correlation between refractive, corneal and lenticular astigmatism and higher order aberrations (hoa) in refractive surgery candidates methods: this cross-sectional descriptive-analytical study consisted of 400 eyes (200 patients) who were referred between 2011 to 2013 to farabi eye hospital for refractive surgery. refraction, topography and aberrometry were performed t...
