Three-dimensional topographic changes of anterior chamber depth following phacoemulsification with intraocular lens implantation in cataract patients

Purpose To investigate the three-dimensional topographic changes of anterior chamber depth (ACD) following cataract surgery. Methods Seventy-eight eyes with age-related cataract undergoing phacoemulsification and intraocular lens (IOL) implantation were retrospectively enrolled. Participants were evaluated with Pentacam for ACD topography before and approximately four weeks after the surgery. The absolute changes of ACD (AACD) and the relative changes of ACD (RACD) topography were calculated, and three-dimensional topographic contours were plotted. The influence of age, gender, distance to corneal apex (DCA), temporal–nasal and superior–inferior on AACD and RACD was analyzed. Results Both AACD and RACD were negatively correlated with the DCA ( p
