Purpose: To investigate the long-term effect of phacoemulsification on IOP in patients with ocular hypertension and open-angle glaucoma.




Setting: Three multispecialty ophthalmology practices and one glaucoma specialty group.

Design: Retrospective comparative case series.

Methods: Review of medical records of patients with open-angle glaucoma or ocular hypertension who had had unilateral phacoemulsification (without prior or concurrent ophthalmic procedure) with the fellow eye remaining phakic at least 3 years post-operatively.

Results: Pre-operatively, the IOP in the surgical and fellow eyes in the 29 patients was 15.66 mm Hg3.33 (SD) and 15.644.24 mm Hg (P=.98), respectively. Post-operatively, it was 13.562.04 mm Hg and 14.922.85 mm Hg, respectively, at 4.5 months (P=.06); 14.883.20 mm Hg and 15.273.19 mm Hg, respectively, at 1 year (P=.67); 14.162.61 mm Hg and 14.952.79 mm Hg, respectively, at 2 years (P=.37); and 14.683.44 mm Hg and 14.682.68 mm Hg at 3 years (P=1.00), respectively. There was no significant difference in the mean number of IOP-lowering medications used in the surgical (1.961.40) and fellow eyes (2.081.44) post-operatively (P=.77).

Conclusions: In a cohort of ocular hypertensive and glaucoma patients, uncomplicated phacoemulsification had no significant IOP-lowering effect compared with the phakic fellow eye for up to 3 years post-operatively. There was also no difference between the mean number of post-operative IOP-lowering medications used in the surgical and fellow eyes.
