AI Summary
This study found no significant difference in visual acuity, IOP, or medication needs between 1-site and 2-site phacotrabeculectomy, suggesting both are equally effective options for combined surgery.
Abstract
Purpose
To compare the results of 1-site versus 2-site combination glaucoma filtration and phacoemulsification surgery with respect to visual acuity, intraocular pressure (IOP), and glaucoma medication requirements via a case control study.
Methods
Results of 2-site phacotrabeculectomy surgery in 64 eyes of 59 patients were retrospectively reviewed with a minimum follow-up of 1 year. The 2-site procedures were compared with a randomly chosen control group of 71 1-site phacotrabeculectomies performed by the same surgeon.
Results
The presurgical visual acuity, IOP, and glaucoma medication requirements did not differ significantly between the 2 groups. Mean final postoperative results at 1 year for 2-site versus 1-site eyes, respectively, were visual acuity 0.32 +/- 0.353 (SD) and 0.32 +/- 0.37 (P = .99), IOP 15.0 +/- 3.7 mm Hg and 15.1 +/- 6.3 mm Hg (P = .97), and glaucoma medication requirements 0.43 +/- 0.90 and 0.61 +/- 1.1 (P = .52).
Conclusion
There was no statistically significant difference in the final visual acuity, IOP, or glaucoma medication requirements between the 2-site and 1-site groups.
