Objective: To evaluate changes in intraocular pressure (IOP) following uneventful phacoemulsification cataract extraction with posterior chamber intraocular lens implantation (Phaco/PC IOL) in primary open-angle glaucoma (POAG) patients.

Methods: The authors retrospectively reviewed preoperative and postoperative IOP in 31 consecutive medically-controlled POAG patients who underwent uneventful Phaco/PC IOL. None of the patients had prior intraocular surgery.

Results: The mean preoperative IOP in the POAG group was 18.1+/-3.1 mm Hg with patients receiving a mean of 1.7 antiglaucoma medications. With a mean follow-up of 16.4 months, the average postoperative IOP in the POAG group was 15.2+/-2.9 mm Hg (P < .001, Student's t test) with patients receiving a mean of 0.7 antiglaucoma medication (P < .001).

Conclusions: Phaco/PC IOL may be associated with a significant decrease in IOP in POAG patients, allowing for decreased postoperative antiglaucoma medication.
