Evaluation of Visual Outcomes After Myopic LASIK

Medical University of South Carolina (MUSC)

Status: Completed

Conditions: Myopia; Astigmatism; Myopic Astigmatism

Treatments: Procedure: Wavefront-guided LASIK; Procedure: Conventional LASIK

Study type: Interventional

Funder types: Other

Identifiers

NCT00366743

MRC-05-001

Details and patient eligibility

About

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.

Full 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.
