Evaluation of the effect of corneal collagen cross-linking for keratoconus on the ocular higher-order aberrations
BACKGROUND Corneal collagen cross-linking (CXL) is the only treatment currently available to arrest the progression of keratoconus. The procedure consists of photopolymerization of stromal collagen fibers induced by combined action of a photosensitizing substance (riboflavin or vitamin B2) and ultraviolet-A light. PURPOSE To determine changes in the ocular higher-order aberrations (HOAs) afte...
متن کاملAdditive effect of repeated corneal collagen cross-linking in keratoconus.
PURPOSE To report the long-term clinical outcome in a patient diagnosed as having bilateral progressive keratoconus who received a single corneal collagen cross-linking (CXL) treatment in the right eye and repeated CXL in the left eye. METHODS Observational case report. Topographical changes were assessed by high-resolution Scheimpflug imaging. The right eye underwent a standard epithelium-of...
متن کاملKeratoconus and corneal collagen cross-linking
Keratoconus, a degenerative disorder of the cornea, causes significant visual distortion and photophobia. Diagnosed in early life, it has a considerable influence on the patient’s daily activities and visual needs. A study of the rural population in Central India gave a prevalence of 2.3% +/0.2% among those aged 30 years and above.[1] The conventional treatment of keratoconus has been the fitti...
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 aberration 4 years after corneal collagen cross-linking
PURPOSE Corneal collagen cross-linking (CXL) is a treatment strategy used in keratoconic eyes. Evaluation of long-term changes of higher-order aberrations (HOAs) after CXL is useful in understanding the efficacy of this procedure in improving optical, refractive, and visual acuity. This study aims to investigate the long-term effect of CXL on ocular HOA in patients with progressive keratoconus ...
