OBJECTIVE: To compare results of filtration combined with either phacoemulsification or the Blumenthal technique of manual small-incision cataract surgery. MATERIAL AND METHODS: Records of glaucoma 'triple' operations from March 1997 to May 2000 were reviewed. Seventy-eight eyes (70 patients) that underwent phaco-triple were compared with 86 eyes (80 patients) that underwent the Blumenthal technique of manual small-incision cataract surgery combined with filtration (Blumenthal triple). Three minutes of 0.4 mg/ml mitomycin was used in all eyes. Posterior chamber intraocular lenses (IOLs) were implanted through 5.5-mm incisions in both groups. Outcome measures were intraocular pressure (IOP) reduction and achievement of target IOP. Fourteen patients who underwent phacoemulsification-triple in one eye and Blumenthal triple in the other eye were also evaluated separately. RESULTS: The minimum follow-up period was six months (range, 6-30 months). At last follow-up review, mean reduction in IOP was 17.7 mmHg (± 9.3 mmHg) in the phaco group and 17.1 mmHg (± 10 mmHg) in the Blumenthal group. At last visit, target IOP was achieved in 75.6% of the phaco group and 73% of the Blumenthal group. There was no significant difference between groups in IOP reduction or achievement of target IOP. In the 14 patients who had undergone phaco-triple in one eye and Blumenthal-triple in the other, there was no inter-eye difference in IOP reduction. CONCLUSIONS: In this small retrospective study, the authors could not demonstrate a difference in IOP outcomes between the two procedures.
