Results of phacoemulsification in eyes with preexisting glaucoma filters

To evaluate the intraocular pressure (IOP), best corrected visual acuity (BCVA), and glaucoma medication requirements in patients having phacoemulsification after preexisting glaucoma filters. Ophthalmic Consultants of Boston, Boston, Massachusetts, USA. A retrospective analysis of 58 eyes that had temporal phacoemulsification via a clear corneal (32 eyes) or a scleral tunnel (26 eyes) approach after filtration surgery was performed with a minimum follow-up of 12 months. Two-tailed homoscedastic t tests were used for statistical analysis. The mean preoperative IOP in all eyes was 11.8 mm Hg ± 4.2 (SD), and the mean final postoperative IOP was 13.7 ± 4.6 mm Hg ( P
