Abstract
PURPOSE: To evaluate intraocular pressure (IOP) immediately after cataract surgery with or without ab interno trabeculectomy (Trabectome) and whether trabeculectomy-related hyphema increases the risk for IOP spikes. SETTINGS: Private glaucoma practice. DESIGN: Retrospective interventional nonrandomized comparative chart review. METHODS: Intraocular pressure was measured 3 to 4 hours and 20 hours postoperatively. RESULTS: The combined group comprised 73 eyes of 73 patients and the cataract-only group, 75 eyes of 75 patients. The mean preoperative IOP was 15.8 mm Hg ± 3.6 (SD) and 14.9 ± 3.0 mm Hg, respectively (P = .09). In the combined group, the IOP decrease was significant at 3 to 4 hours (P = .0003) and 20 hours (P = .0007). In the cataract-only group, the IOP increased significantly (P < .0001 and P = .0035, respectively). The mean IOP was significantly lower in the combined group than in the cataract-only group at 3 to 4 hours (12.8 ± 5.9 mm Hg versus 19.7 ± 7.5 mm Hg) and 20 hours (12.7 ± 7.0 mm Hg versus 17.2 ± 5.9 mm Hg) (both P < .0001). Significantly fewer eyes in the combined group than in the cataract-only group had IOP spikes (overall, P = .0077; 3 to 4 hours, P = .001). Hyphema occurred in 35 eyes (47.9%) in the combined group; however, the IOP was similar with or without hyphema. Only 1 eye with an IOP spike in the combined group had hyphema. CONCLUSION: Combining ab interno trabeculectomy and cataract surgery reduced short-term postoperative IOP and the incidence of IOP spikes despite the common hyphema.
