A Study of Daytime Changes in Corneas with Fuchs Dystrophy

Overview

About this study

The purpose of this study is to determine changes in corneal thickness and backscatter after first morning eye-opening across a range of fuchs endothelial dystrophy severity, and in healthy corneas. Corneal measurements will be made with a Scheimpflug camera and associated changes in visual acuity and glare (forward scatter) will be determined.
