Optical Low Coherence Reflectometry Enables Preoperative Detection of Zonular Weakness in Pseudoexfoliation Syndrome

The purpose of the study was to evaluate optical ocular components in patients with pseudoexfoliation syndrome using optical low coherence reflectometry. A prospective cohort study of 224 eyes of patients planned for cataract surgery was conducted from January 2009 until July 2009. Patients were divided in two groups: the first group of 47 eyes with cataract complicated with pseudoexfoliation syndrome and the control group of 177 eyes with uncomplicated cataract. Each group was further divided into two subgroups based on its refractive state: emmetropes and hypermetropes. The optical low coherence reflectometry biometer LENSTAR® LS 900® was used to define ocular optical components.
