OBJECTIVE To evaluate intraocular pressure (IOP) control after extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens (PCIOL) implantation in patients with capsular glaucoma (CG) and coexisting cataract. METHODS This prospective study included 20 patients (20 eyes) having CG and cataract whose IOPs were under 22 mm Hg and controlled with antiglaucoma medication. All patients had ECCE with PCIOL implantation and the follow-up period was at least 18 months. IOP was measured postoperatively at 3, 6, 9, 12 and 18 months and compared with preoperative IOP. RESULTS Following the cataract extraction, PCIOL implantation produced a statistically significant reduction in IOP at all time points compared with the preoperative IOP during the study period (p < 0. 001). The mean preoperative IOP was 18.25 +/- 1.83 mm Hg; postoperatively at 1 month, it was 13.45 +/- 2.06 mm Hg; at 3 months 14.80 +/- 2.50 mm Hg; at 6 months 15.35 +/- 1.27 mm Hg, at 12 months 14.85 +/- 1.87 mm Hg and at 18 months 15.15 +/- 1.42 mm Hg (p < 0. 0008). The mean reduction in IOP was 16.98% from baseline at 18 months postoperatively. The mean number of antiglaucoma medication was reduced from 1.35/eye preoperatively to 0.60/eye postoperatively at 18 months (p < 0.0007). CONCLUSIONS The result of our study revealed that ECCE with PCIOL implantation may be a reliable choice in controlling IOP in patients with CG.
