Effect of Anterior Chamber Depth on Intraocular Pressure after Uneventful Phacoemulsification Surgery in Nonglaucomatous Eyes with Cataract

Purpose: To evaluate the effect of preoperative anterior chamber depth (ACD) on intraocular pressure (IOP) after uneventful\udphacoemulsification and intraocular lens (IOL) implantation in nonglaucomatous eyes.\udMaterial and Method: The medical records of fifty-five patients (30 male and 25 female) were reviewed retrospectively.\udThe patients who had undergone uneventful phacoemulsification and IOL implantation were divided into two groups\udaccording to the values of preoperative ACD: 30 eyes in group 1 (ACD≤3.27 mm) and 25 eyes in group 2 (ACD>3.27\udmm). IOP was measured using non-contact tonometer preoperatively and postoperatively (1 day, 1 week, 1 month,\udand 3 months).\udResults: Three months after phacoemulsification and IOL implantation, the mean IOP decreased 23.6% in group 1 and\ud13.7% in group 2. There was a statistically significant difference between the groups (p= 0.025).\udDiscussion: The mean IOP decreases in eyes with shallow anterior chamber more than in normal eyes after uncomplicated\udphacoemulsification and IOL implantation.
