No results posted yet for this study

Summary

An aberrometer measures visual aberrations by mapping how light rays travel through the eye and by providing maps using colored gradients to represent the magnitude of refractive errors of the eye.

The purpose of this study is to compare 4 different aberrometers -Wavescan (Visx Technology), Zywave (Bausch \& Lomb), Ladarwave aberrometer (Alcon Inc.) and Allegro Analyzer (Alcon Inc). In particular, the investigators propose to focus on the ability of these devices to display the higher order visual aberrations and to compare the quality of outputs from these 4 devices in normal healthy subjects.
