Examining Higher Order Aberration in Eyes after DSEK

Abstract

The fundamental idea of this work is to modify Descemet’s Stripping Endothelial Keratoplasty DSEK mathematical model by incorporating the Zernike polynomial to examine Higher Order Aberrations (HOA). This model has been developed in a way that can identify the type of aberration occurring after a keratoplasty. Model variables are compared with the data available in already published literature. Surgically induced Higher Order Aberrations (HOA) and change in corneal power are the main outcome measures. Eye illness and their treatments have always been an interesting topic of discussion for researchers. Mechanical and software engineers have managed to helped ophthalmologists by developing advanced machines that can identify the patients’ complaints in seconds. Moreover, several new and advanced surgical procedures have been adopted for eye problems. One amongst them is eye aberration. Only recently has it become possible to detect one type of aberration (Astigmatism & Higher Order Aberrations) with special equipments. However, it is still not easy to identify aberrations as Myopia and Hyperopia. This paper studies the induced eye aberrations caused by DSEK and their detection through a modified DSEK model.
