Evaluation of Visual Outcomes After Myopic LASIK

August 17, 2006 updated by: Medical University of South Carolina

Analysis of Visual Outcomes, Contrast Sensitivity, Glare, Induction of High Order Aberrations and Wavefront Technology, Following LASIK Surgery

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.
