متن کاملEvaluation of Intereye Corneal Asymmetry in Patients with Keratoconus. A Scheimpflug Imaging Study
PURPOSE To assess the correlation between keratoconus severity and intereye asymmetry of pachymetric data and posterior elevation values and to evaluate their combined accuracy in discriminating normal corneas from those with keratoconus. METHODS This study included 97 patients: 65 subjects with bilateral normal corneas (NC) and 32 with keratoconus (KC). Central corneal thickness (CCT), thinn...
متن کاملCorneal changes in progressive keratoconus after cross-linking assessed by Scheimpflug camera.
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...
متن کاملNatural history of corneal haze after collagen crosslinking for keratoconus and corneal ectasia: Scheimpflug and biomicroscopic analysis.
PURPOSE To determine the natural history of collagen crosslinking (CXL)-associated corneal haze measured by Scheimpflug imagery and slitlamp biomicroscopy in patients with keratoconus or ectasia after laser in situ keratomileusis. SETTING Cornea and refractive surgery subpecialty practice, United States. DESIGN Prospective randomized controlled clinical trial. METHODS The treatment group ...
متن کاملCorneal Changes After Collagen Crosslinking for Keratoconus Using Dual Scheimpflug Imaging
PURPOSE To evaluate corneal changes after collagen crosslinking (CXL) therapy for keratoconus (KCN) using the Galilei dual Scheimpflug analyzer. METHODS This prospective, nonrandomized clinical study included 35 eyes of 32 keratoconus patients who had undergone CXL. The eyes were saturated with riboflavin solution and were subjected for 30 minutes to ultraviolet-A (UV-A) light with irradiance...
