Evaluation of Visual Outcomes After Myopic LASIK

Not Applicable

Completed

• Conditions: Myopia; Astigmatism; Myopic Astigmatism

• Registration Number: NCT00366743
• Lead Sponsor: Medical University of South Carolina

Brief Summary

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.

Detailed Description

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.
