Evaluation of Corneal Aberrometry Parameters Before and After Cross-Linking in Patients with Keratoconus
Background and Objective: In the last decade, cross-linking (CXL) has been widely used for treating people with progressive keratoconus. The present study aimed to compare corneal aberrometry parameters before and after CXL in patients with keratoconus. Materials and Methods: In this cross-sectional study, 67 patients with keratoconus referred to Farshchian Sina Medical Education Center, Hamad...
متن کاملFusion of Different Corneal Parameters to Improve the Diagnosis of Keratoconus
Purpose: To diagnose keratoconus from healthy eyes, as well as suspected keratoconus. Methods: Certain parameters were extracted from Casia, Corvis, and Pentacam HR devices for 3 groups of healthy, with keratoconus, and suspected keratoconus. This study was performed on 340 eyes with keratoconus, 310 normal eyes, and 350 suspected keratoconus. The processing method involved the fusion of featur...
متن کاملInfluence of corneal cross-linking for keratoconus on several objective parameters of dry eye.
PURPOSE To evaluate the potential influence of corneal cross-linking (CXL) with ultraviolet-A light and riboflavin in keratoconic eyes on several objective parameters of dry eye syndrome. METHODS This prospective single center study included 30 consecutive eyes of 16 patients that underwent CXL with riboflavin and ultraviolet-A treatment (epithelial removal, 30 minutes soaking with riboflavin...
متن کاملCorrelation of Corneal Endothelial Cell Density with Corneal Tomographic Parameters in Eyes with Keratoconus
Objectives To examine changes in corneal endothelial cell density (ECD) in different stages of keratoconus and evaluate its correlation with corneal tomographic parameters. Materials and Methods Two hundred six patients with keratoconus were enrolled in the study. Corneal topography was performed by Sirius (CSO, Italy), which has a rotating Scheimpflug camera and a Placido disc topographer. A...
متن کاملIntraocular pressure in a cohort of healthy eastern European schoolchildren: variations in method and corneal thickness
BACKGROUND Intraocular pressure (IOP) in the developing eye of a child is not always easy to measure and there is no technique that is known to be the most accurate for the young eye. Measurements are needed on many cohorts of children with different tonometers to determine how the values correlate between instruments, whether corneal parameters affect readings and whether correlations between ...
