OBJECTIVE To assess if diabetes, in patients without cataracts or diabetic retinopathy, alters the densitometric values of the lens and to what degree this occurs. METHODS A total of 93 patients, divided into two groups, were studied: the diabetic patients had a visual acuity equal to or greater than 0.8 and normal eye funduscopy, and the control group consisted of healthy patients of a simil...

PURPOSE To evaluate corneal changes after corneal cross-linking (CXL) in progressive keratoconus with Scheimpflug imaging. METHODS This prospective analysis included 40 eyes from 22 patients with progressive keratoconus. Corneal CXL was performed in 25 eyes (CXL group) and 15 fellow eyes served as controls (control group). Uncorrected (UDVA) and corrected distance visual acuity (CDVA), thinne...

Background and Objective. Evaluation of agreement, repeatability, and reproducibility of central and minimal corneal thickness (CCT and MCT) measurements obtained by SOCT, the Scheimpflug system, and ultrasound pachymetry. Materials and Methods. 28 eyes of healthy patients were enrolled. Pachymetry measurements were performed with SOCT, the Scheimpflug system, and ultrasound instrument. Each me...

PURPOSE To assess the agreement between the elevation and curvature measurements of the anterior and posterior corneal surfaces obtained using the Galilei Dual Scheimpflug Analyzer and those obtained using the Pentacam single Scheimpflug system. METHODS This prospective, noninterventional, diagnostic study was conducted at the Department of Ophthalmology at the American University of Beirut (...

PURPOSE To test correlations between Scheimpflug optical densitometry and ocular higher-order aberrations (HOAs) in patients with mild nuclear cataract. SETTING Cornea and Refractive Surgery Department, Hospital de Braga, Braga, Portugal. DESIGN Retrospective single-center study. METHODS In eyes with mild nuclear cataract, lens densitometry was evaluated by Scheimpflug imaging (Pentacam H...

PURPOSE To evaluate changes in crystalline lens densitometry following corneal cross-linking (CXL) in keratoconic patients. METHODS In a quasi-experimental study, three-dimensional lens densitometry was performed using the Pentacam Scheimpflug camera (Oculus Optikgerate GmbH, Wetzlar, Germany) at baseline and six months after CXL. Densitometry was performed in a fixed area of 2 inch × 1 inch ...
