Topical plus subconjunctival anesthesia for phacotrabeculectomy: One year follow-up

Abstract

Purpose: To evaluate the results of topical plus subconjunctival anesthesia for phacotrabeculectomy surgery and postoperative glaucoma control over 1 year.Setting: Pacific Eye Center, Brisbane, Australia.Methods: In this retrospective study of consecutive patients with glaucoma and cataract, topical plus subconjunctival anesthesia was used for combined phacoemulsification, posterior chamber intraocular lens implantation, and trabeculectomy (phacotrabeculectomy). Patients with proliferative diabetic retinopathy or neovascular glaucoma were excluded.Results: Thirty-eight eyes had phacotrabeculectomy using topical plus subconjunctival anesthesia over 2 years. Patients reported no discomfort intraoperatively or postoperatively, and none required intravenous sedation. Eighty-one percent of patients achieved a best corrected visual acuity of 20/40 or better 6 months after surgery. Mean drop in intraocular pressure (IOP) was 5.91 mm Hg at 3 months and 5.86 mm Hg at 12 months, at which time IOP was controlled without additional medication in 72% of patients. There were no serious complications postoperatively.Conclusion: In this series, no patient reported intraoperative or postoperative discomfort and surgical results were excellent in terms of visual outcome and IOP control.
