| Summary: | Purpose: This study aimed to evaluate the relationship between preoperative ocular biometric parameters and intraocular pressure (IOP) reduction after phacoemulsification in non-glaucomatous eyes. Methods: The charts of non-glaucomatous patients who underwent phacoemulsification and lens implantation were retrospectively reviewed. IOP was measured preoperatively and 3 months after surgery. The change in IOP and its relation to ocular biometric parameters, including anterior chamber depth (ACD), lens thickness (LT), axial length (AL), and central corneal thickness (CCT), measured preoperatively by LENSTAR LS 900 (Haag-Streit, Inc., Koeniz, Switzerland), were evaluated. The impact of each parameter on the alteration in IOP was assessed using a regression model. Results: The analysis included 171 eyes of 145 patients, with a mean age of 68.7 ± 11 years. The average IOP reduction following cataract surgery was 3.0 ± 2.9 mmHg, decreasing from a preoperative mean of 16.3 ± 2.8 mmHg. The amount of IOP reduction showed statistically significant correlations with preoperative ocular parameters. Eyes with shallower anterior chambers demonstrated a greater IOP reduction (r = −0.307, <i>p</i> = 0.034), as did those with thicker lenses (r = 0.383, <i>p</i> = 0.026). Multivariate regression analysis further confirmed that higher preoperative IOP, shallower ACD, and thicker lenses were independently associated with greater postoperative IOP decreases (<i>p</i> < 0.001). AL and CCT did not exhibit significant associations with IOP reduction. Conclusions: The amount of IOP reduction is significantly greater in eyes with higher preoperative IOP, thicker lenses, and shallower anterior chamber after cataract surgery in non-glaucomatous eyes. |
