The investigators are analyzing outcomes of topography-guided LASIK surgery in participants with myopia and myopic astigmatism
Condition or disease
Procedure: Topography-guided LASIK
The investigators are analyzing outcomes of topography-guided LASIK surgery in participants with myopia and myopic astigmatism. The investigators will be monitoring changes in anterior segment optical coherence tomography epithelial thickness maps. The investigators will compare preoperative maps to postoperative maps at one, three, six and twelve months. In addition, the investigators will measure changes in epithelial maps from postoperative month through twelve months to help understand what is happening to the corneal epithelium to try to explain why UDVA and CDVA improves over time
