Purpose: To investigate the effects of phacoemulsification in glaucomatous eyes with functioning Baerveldt tube shunts. Setting: Department of Ophthalmology, Mayo Clinic College of Medicine, Rochester, Minnesota, USA. Methods: This retrospective analysis followed 9 eyes of 8 patients with functioning Baerveldt tube shunts who had clear corneal phacoemulsification. Intraocular pressure (IOP), number of glaucoma medications, corneal thickness, visual acuity, and additional glaucoma surgery were measured. Results: The mean follow-up was 21 months ± 3 (SD) (range 17 to 25 months). The mean change in IOP and the number of glaucoma medications used did not significantly change at 1 month (P>.19), 1 year (P>.17), or the last follow-up (P>.17). At the last examination, 2 eyes had IOP increases of 2 to 4 mm Hg, 3 eyes had no change, and 4 eyes had decreases of 4 to 7 mm Hg. Intraocular pressure increased in 1 eye at 8 months and required a tube shunt revision. No eye developed corneal decompensation. Visual acuity improved in 8 eyes; the mean improvement was 4 ± 3 Snellen lines. Conclusion: In most cases, phacoemulsification in glaucomatous eyes with a functioning Baerveldt tube shunt improved vision and maintained control of IOP.
