Abstract
Objective: To describe foveal thickness and foveal anatomical changes after uneventful phacoemulsification surgery. Design: Interventional case control study. Participants: Both eyes of healthy phakic patients presenting to the American University of Beirut Medical Center Eye clinic for phaco-emulsification surgery in one eye (the study eye). The fellow eye served as control. Methods: OCT images of the macula were taken pre-operatively, then on a weekly basis for 12 weeks post-operatively. Outcomes: post op foveal thickness and morphological changes. Results: From the originally recruited 66 patients, 52 patients (104 eyes) completed the study. A transient increase in foveal thickness was observed in 36/52 (69%) eyes mostly between weeks 4 and7 post operatively. Twenty-seven eyes developed anatomic changes including: microcysts in 15 eyes (55%), regular cysts in 6 eyes (22%), and epiretinal membranes in 6 eyes (11.5%). Changes appeared as early as 1 week post operatively, and lasted on the average 4 weeks. Conclusion: Uncomplicated cataract surgery can lead to transient thickening of the macula as well as morphological changes.
