Abstract Details

Purpose:

To evaluate the relationship of preoperative anterior segment parameters with intraocular pressure (IOP) reduction after phacoemulsification in non-glaucomatous eyes.

Setting:

Recep Tayyip Erdogan University School of Medicine, Department of Ophthalmology

Methods:

The charts of non-glaucomatous patients underwent phacoemulsification and lens implantation were retrospectively reviewed. IOP was measured preoperatively and 8 weeks after surgery. Change in IOP and its relation to anterior segment parameters, which were measured by LENSTAR LS 900 (Haag-Streit, Inc., Koeniz, Switzerland) preoperatively, including anterior chamber depth (ACD), lens thickness (LT), axial length (AXL) and anterior depth (AD) were evaluated. Preoperative IOP, LT, AXL and ACD were assessed as predictors of IOP reduction after surgery.

Results:

167 eyes of 145 patients were included in the analysis. The overall mean age was 68.7 ±11 years. The average IOP reduction was 2.25±2.1 mmHg, from a preoperative mean of 16.1 ±2.26 mmHg. The amount of IOP reduction was significantly greater in eyes with thicker lenses (Rho = 0.385; p= 0.026) and shallower anterior chambers (Rho= 0.415, p= 0.034) and both showed statistically significant correlation with IOP reduction after surgery. In multivariate linear regression analysis, higher preoperative IOP, shallower ACD and small AD was significantly associated with higher IOP decrease (p < 0.001); AL showed no significant association.

Conclusions:

The amount of IOP reduction after cataract surgery in non-glaucomatous eyes is significantly greater in eyes with thicker lenses and shallower anterior chamber.
