ABERROMETRY CHANGES AND IOL DISLOCATION

Abstract

Purpose. To study the aberrometric changes in eyes with posterior IOL decentration. Material and methods. All ophthalmic examinations were performed including Hartmann-Shack WASCA and CRS-Master aberrometry system (Carl Zeiss Meditec). Ocular wavefront aberrations were measured in 14 eye with IOL dislocation (main group) and 52 eyes with a normal central intracapsular position of IOL and 22 emmetropic (control groups). Results. We revealed total aberrations and HOAs (especially trefoil, spherical-like and mild positive vertical coma) increasing in eyes with IOL dislocation. However, the accuracy of IOL decentration aberrometry depends on the capsular bag opacities, secondary cataract and a pronounced level of IOL dislocation. Conclusions. All aberrations and especially high order aberrations (HOAs) increased in the eyes with IOL dislocation.
