The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by:
Medical University of South Carolina
  Purpose
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.

Condition Intervention
Myopia Astigmatism Myopic Astigmatism Procedure: Conventional LASIK Procedure: Wavefront-guided LASIK

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: Analysis of Visual Outcomes, Contrast Sensitivity, Glare, Induction of High Order Aberrations and Wavefront Technology, Following LASIK Surgery
