  • Title: Temporal corneal phacoemulsification in filtered glaucoma patients.
    Author: Caprioli J, Park HJ, Kwon YH, Weitzman M.
    Journal: Trans Am Ophthalmol Soc; 1997; 95():153-67; discussion 167-70. PubMed ID: 9440168.
    Abstract:
    PURPOSE: To evaluate the effect of temporal clear corneal phacoemulsification on intraocular pressure (IOP) in eyes that had prior trabeculectomy. DESIGN: Retrospective case-control study. PATIENTS: Forty consecutive patients (cases; TRAB-PHACO group) who underwent temporal corneal phacoemulsification subsequent to trabeculectomy were identified. Forty patients (controls; TRAB group) who had trabeculectomy alone were matched to the cases for length of follow-up, age, IOP, number of anti-glaucoma medications, number of 5-fluorouracil (5-FU) injections, race, sex and diagnosis. MAIN OUTCOME MEASURES: Comparison of IOP before and one year after phacoemulsification in the TRAB-PHACO group, and comparison with the TRAB group. Survival analysis of IOP control after trabeculectomy in the TRAB-PHACO and TRAB groups. RESULTS: In the TRAB-PHACO group, IOP one year after phacoemulsification was not significantly different from the pre-phacoemulsification IOP value (p = 0.65). Kaplan-Meier survival analysis showed that the rates of IOP control at 3, 6 and 9 years after trabeculectomy in the TRAB-PHACO group were 80%, 66% and 44%; in the TRAB group these were 79%, 69% and 55%. These survival curves were not statistically different (p = 0.55). CONCLUSIONS: Cataract surgery by temporal clear corneal phacoemulsification in eyes with filtering blebs after trabeculectomy does not adversely affect long term IOP control.
