Foveal thickness after phacoemulsification as measured by optical coherence tomography

摘要

Background: Despite a significant body of research, no consistency on postoperative foveal thickness as measured by optical coherence tomography (OCT), can be recorded. The purpose of our study was to evaluate the effect of uncomplicated cataract surgery in the thickness of the retina in the foveal area during the early postoperative period.Methods: In a prospective study, 79 eyes were assessed by OCT, on day 1, and weeks 2 and 4 after uncomplicated phacoemulsification with intraocular lens implantation in the Athens University Clinic. The outcome measure was the thickness of the retina in the foveal area.Results: The thickness of the retina preoperatively is significantly smaller (150.4 ± 18.8) (p?< 0.05) than the thickness of the retina on day 1 (171.8 ± 21) and week 2 (159.7 ± 19) and returned to the initial levels on week 4 (152 ± 17.1). The estimated correlation coefficients between preoperative and postoperative thickness of the retina were significant (p
