Abstract
OBJECTIVE: To review the effect of phacoemulsification surgery in eyes with chronic hypotony following trabeculectomy with mitomycin C. DESIGN: Retrospective analysis of all eyes that underwent phacoemulsification surgery for symptomatic cataracts and had a preoperative diagnosis of chronic hypotony (intraocular pressure [IOP] </=6 mm Hg) for at least 6 months following trabeculectomy with mitomycin C. Each case had at least 6 months' follow-up after the phacoemulsification surgery. SETTING: A tertiary care referral center. INTERVENTION: Clear cornea phacoemulsification surgery, with minimal perioperative anti-inflammatory medication and retention of viscoelastic in eyes at case conclusion. MAIN OUTCOME MEASURES: Intraocular pressure, visual acuity, and complications. RESULTS: Nine eyes of 9 patients were identified. Mean preoperative IOP was 4. 2 +/- 1.4 mm Hg; the mean postoperative IOP was 7.3 +/- 2.8 mm Hg (P=.009). Intraocular pressure increased in all but 2 eyes. One of these 2 eyes experienced an acutely elevated IOP (34 mm Hg) on postoperative day 4, which dropped back to preoperative levels after trabeculectomy flap needling. Mean preoperative visual acuity was 20/300; mean postoperative visual acuity was 20/40. CONCLUSION: Phacoemulsification surgery may be associated with a statistically significant elevation in IOP in previously filtered eyes with hypotony, resulting in resolution of hypotony in some of these challenging cases.
