BACKGROUND: Many of the previous studies which dealt with the influence of cataract surgery on intraocular pressure, were performed retrospectively and based on heterogenous groups of patients. Therefore, the purpose of this study was to prospectively assess the effect of phacoemulsification and posterior chamber intraocular lens (IOL) implantation on intraocular pressure (IOP) under standardized conditions in patients with and without open-angle glaucoma. PATIENTS AND METHODS: Overall, 52 patients were recruited for the study: 34 eyes with normal IOP, and 16 eyes with open-angle glaucoma were operated on usingwith the same technique. RESULTS: Mean IOP in patients with cataract and without glaucoma was 15.1 mmHg preoperatively. Six months postoperatively these patients showed a mean decrease of IOP of 11.9% (1.8 ± 3,8 mmHg; p = 0.027); after 12 months IOP showed a decrease of 18.5% (2.8 ± 3.5 mmHg; p = 0.0001). In patients with glaucoma, mean preoperative IOP was 17.3 mmHg. IOP was reduced by 23.7% (4.1 ± 6.0 mmHg; p = 0.017) six months after cataract surgery, and 22.6% (3.9 ± 4.5 mmHg; p = 0.005) 12 months after the operation. In six of 16 eyes, the antiglaucoma medication could be suspended. CONCLUSIONS: Reduction of IOP is a positive side-effect of phacoemulsification and posterior chamber IOL implantation and should be considered when indicating cataract surgery in patients with glaucoma and only slight elevation of IOP.
