Intraocular pressure reduction following phacoemulsification cataract extraction with posterior chamber lens implantation in glaucoma patients.

BACKGROUND AND

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.

PATIENTS AND

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).

CONCLUSION

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