PURPOSE: To investigate the influence of uneventful phacoemulsification on anterior chamber depth (ACD), iridocorneal angle (ICA) width, and intraocular pressure (IOP) in nonglaucomatous eyes with open ICA preoperatively. METHODS: Fifty-three eyes of 49 patients were evaluated for six months postoperatively. The nonparametric Wilcoxon signed rank test was used to compare preoperative and postoperative IOP, ACD, and ICA width. Univariate and multivariate regression analyses were used to evaluate the relationships between IOP, ACD, and ICA width and between preoperative patient characteristics. RESULTS: The mean preoperative IOP of 15.1 ± 2.8 mmHg (SD) dropped postoperatively to 13.4 ± 3.4 mmHg at one day, 13.3 ± 2.6 mmHg at one week, 13.2 ± 3.1 mmHg at one month, 13.3 ± 2.7 mmHg at three months, and 14.1 ± 2.5 mmHg at six months (p < 0.05). The mean preoperative ICA grade of 2.97 ± 0.72 increased to 3.55 ± 0.48 at one week and 3.68 ± 0.45 at one month (p < 0.05). The mean preoperative ACD of 3.06 ± 0.49 mm increased to 3.57 ± 0.47 mm at four weeks, 3.69 ± 0.32 mm at one month, and 3.70 ± 0.36 mm at three months (p < 0.05). The IOP decrease was not correlated with the changes in ICA width or ACD. Multiple regression analysis showed preoperative IOP was the single predictor of the postoperative IOP drop (p < 0.001). CONCLUSIONS: In nonglaucomatous eyes with an open ICA preoperatively, uneventful phacoemulsification reduced IOP, increased ACD, and widened the ICA. The changes were statistically significant over six months.
