Topography and Higher Order Corneal Aberrations of the Fellow Eye in Unilateral Keratoconus
Objectives Comparison of topography and corneal higher order aberrations (HOA) data of fellow normal eyes of unilateral keratoconus patients with keratoconus eyes and control group. Materials and Methods The records of 196 patients with keratoconus were reviewed. Twenty patients were identified as unilateral keratoconus. The best corrected visual acuity (BCVA), topography and aberration data ...
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 کاملHigher-order aberrations due to the posterior corneal surface in patients with keratoconus.
PURPOSE This study was designed to investigate higher-order aberrations (HOAs) due to the posterior corneal surface in keratoconic eyes compared with normal eyes. METHODS We studied 24 normal and 28 keratoconic eyes. The anterior/posterior corneal heights and pachymetric data were obtained with a rotating Scheimpflug camera. HOAs for 6 mm pupils were calculated from the differences between th...
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 کاملObjective and subjective diagnostic parameters in the fellow eye of unilateral keratoconus
BACKGROUND Keratoconus (KC) is usually a bilateral corneal ectatic disease. For significant asymmetric presentation (so called unilateral KC), the fellow eye has the mildest and earliest form of the disease, which is typically called forme fruste keratoconus. The aim of this study was to evaluate the sensitivity and specificity of parameters derived from a Scheimpflug imaging system (Pentacam) ...
