Influence of Mechanical Properties on Photorefractive Keratectomy Outcome

Abstract

In the 90’s, excimer lasers were introduced in refractive eye surgery for correcting vision errors by reshaping the corneal surface. However, the post-surgical mechanical consequences of removing the tissue have not been analyzed to date. To address this issue, a finite element (FE) model has been developed to reproduce Photorefractive Keratectomy (PRK), in order to investigate surgery’s outcomes depending on mechanical parameters
