In this study we aimed to evaluate the changes in intraocular pressure following uneventful phacoemulsification cataract extraction with posterior chamber intraocular lens implantation in primary open-angle glaucoma patients. We retrospectively reviewed the 27 eyes of 22 patients with primary open-angle glaucoma who underwent cataract surgery and were followed in the glaucoma department of SSK Goztepe Educational Hospital.The preoperative and postoperative visual acuity, antiglaucoma medications, preoperative and postoperative intraocular pressures measured during the first 6 and 12 months postoperatively, 2’st and 3’rd years after the surgery were noted and compared. During the 2 years follow up the posoperative intraocular pressure measurements were found to be significantly lower than the preoperative intraocular pressures. During the 3’rd postoperative year the intraocular pressure started to increse but it still remained significantly lower than the preoperative measurements. All of the patients had two or more Snellen rows increase in visual acuity postoperatively except one patient in whom the visual acuity remained the same. There was a decrease in the antiglaucoma medications postoperatively but this decrease was not statistically significant. In this study we found that there was a statistically significant decrease in the intraocular pressure of patients with primary open-angle glaucoma after uncomplicated phacoemulsification and posterior chamber intraocular lens implantation surgery. The cataract surgery itsself may contribute to the intraocular pressure regulation in patients with primary open-angle glaucoma.
