    Purpose: To investigate the factors that affect the decrease in intraocular pressure (IOP) after cataract surgery. Materials and Methods: Single-center, retrospective, observational case series. Preoperatively, lens thickness (LT), anterior chamber depth (ACD), angle open distance (AOD), lens vault (LV), iris curvature (IC) and iris thickness (IT) were measured. Pressure/depth ratio (PDR), ACD/LT ratio and lens position (LP) were calculated. Pre- and post-surgical IOP were analyzed as absolute value difference and percent change. The effect of each parameter on IOP change was evaluated with a linear regression model. Results: Forty-four eyes of 44 patients (23 female, 52.2%) were analyzed. The mean IOP decreased from 17.47±2.99 mmHg to 15.11±2.34 mmHg in the second postoperative month (p <0.001). The absolute IOP difference was 2.36±1.52 mmHg, and the percent change was 0.13±0.07 %. According to the multivariate linear regression analysis, preoperative IOP and ACD/LT were significant predictors of absolute IOP change (p<0.004, p=0.016, respectively, R2=68.5%). According to the percent IOP change, only preoperative IOP was significant (p=0.031, R2=58.6%). Conclusion: Preoperative IOP and ACD/LT ratio are essential indicators of intraocular pressure change in the non-glaucomatous patient group after cataract surgery. It may be essential to consider these factors for clinical follow-up in patients with a significant reduction in intraocular pressure following cataract surgery.
