PURPOSE: To evaluate the effect of phacoemulsification in functioning filtered glaucoma eyes on intraocular pressure (IOP), and the use of antiglaucomatous medication. To determine the influence of time lapsing between surgeries on the results. METHODS: Twenty eyes of 20 patients treated by phacoemulsification in 1997, who had undergone previous glaucoma filtering surgery in which IOP was well controlled, were evaluated retrospectively. RESULTS: Mean preoperative IOP was 13.2 ± 4.1 mmHg (range: 5-21). Mean IOP had increased after phacoemulsification at all postoperative controls (0.9-2.6 mmHg), but the differences were not significant. Mean score medication increased (0.2-1) after surgery, but the difference was not significant. Mean preoperative IOP was 5.7 mmHg lower in patients who underwent phacoemulsification less than 18 months after trabeculectomy than in those whose surgery was performed later (p < 0.001). Moreover, patients operated on earlier showed an IOP increase after phacoemusification (3.2-3.9 mmHg) during the first six postoperative months (p < 0.05). However, patients who underwent filtering surgery later did not show any significant change in postoperative IOP. Visual acuity (VA) significantly improved after cataract surgery (p < 0.05). VA was equal or better than 0.5 in 43.75% of patients six months postoperatively. CONCLUSIONS: The authors found a slight increase in IOP after phacoemulsification in filtered glaucoma eyes. Reducing the time lapsing between trabeculectomy and phacoemulsification could be a risk factor predisposing to the failure of previously functioning filtering blebs. LA: Spanish
