Trial Outcomes & Findings for Contralateral Comparison of Three Excimer Laser Systems in Performing LASIK (NCT NCT00821236)

NCT ID: NCT00821236

Last Updated: 2013-03-01

Results Overview

Visual acuity measured without glasses or contact lenses. LogMar is a method of measuring visual acuity. Generally speaking, the U.S. population is familiar with 20/20 visual acuity reference. Samples of LogMar equivalent values would be 20/20=0.0 LogMar, 20/25=0.1 LogMar, 20/16=-0.1, etc.
