Purpose. To evaluate the effects of a YAG laser posterior capsulotomy on intraocular pressure (IOP) in glaucoma patients. Methods. We retrospectively studied 69 patients who underwent posterior capsulotomy following cataract or combined cataract-glaucoma surgery and who had a minimum follow-up of six months. We assessed IOP control, number of glaucoma medications required, and need for additional glaucoma surgery following capsulotomy as clinical outcomes. We defined an "unfavorable result" as: a =5 mm Hg sustained rise in IOP, a need for additional glaucoma medications, and/or a need for additional glaucoma surgery. We calculated Kaplan-Meier event rate curves for these "unfavorable results." Mean follow-up was 24.4 ± 12.3 months. Results. 6.3% of patients had an IOP rise of =5 mm Hg one hour post capsulotomy. The actuarial (Kaplan-Meier) rate of any "unfavorable result" was 11.6% at 4 months, 38.1% at 12 months, 46.1% at 24 months, and 52.1% at 36 months following capsulotomy. Conclusions. Progression of glaucoma after YAG capsulotomy is common and may be accelerated by the laser procedure
