Evaluation of Visual Outcomes After Myopic LASIK

Medical University of South Carolina120 enrolled

Overview

The aim of the study was to evaluate visual outcomes, contrast sensitivity, glare testing and high order aberrations induced by different laser technologies and to evaluate differences in aberrometer technology. We hypothesized that there will not be differences among conventional or wavefront guided treatments.

The aim of the study was to evaluate and compare visual outcomes, contrast sensitivity, glare testing and induction of high order aberrations by different laser technologies and to evaluate differences in aberrometer technology.
