Title : the Variability of Corneal and Anterior Segment Parameters

30 Purpose: To analyse, describe and test diverse corneal and anterior segment parameters 31 in normal and keratoconic eyes to better understand the geometry of the keratoconic 32 cornea. 33 34 Method: 44 eyes from 44 keratoconic patients and 44 eyes from 44 healthy patients 35 were included in the study. The Pentacam System was used for the analysis of the 36 anterior segment parameters. New a...

Correlation of Anterior Segment Parameters in Keratoconus Patients

Purpose: To evaluate the corneal asphericity, volume, thickness and keratometry and the correlation among these variables in keratoconus patients. Materials and methods: A total of 1,071 eyes of 810 patients diagnosed with keratoconus were evaluated with a Pentacam (Oculus Optikgerate GmbH). Five groups were established according to the mean keratometry readings: Very mild [K < 44.0 diopters (D...

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...

Relationship among Corneal Biomechanics, Anterior Segment Parameters, and Geometric Corneal Parameters

Purpose. To investigate the relationship between corneal biomechanical parameters, anterior segment parameters, and geometric corneal parameters in a healthy Caucasian group. Methods. This retrospective study included the healthy eyes with best corrected visual acuity of at least 20/40 of 122 Caucasian subjects. The anterior segment parameters and geometric corneal parameters such as corneal vo...

Unilateral corneal endothelial dystrophy and anterior keratoconus.

PURPOSE To describe a case of keratoconus and Fuchs' corneal endothelial dystrophy in the left eye with no corneal disease in the right eye. METHODS A 64-year-old woman presented with visual impairment in her left eye; computer-assisted topographic analysis and specular microscopy were performed in both eyes and left cornea was histopathologically examined. RESULTS Keratoconus was diagnosed...
