PURPOSE: To evaluate the efficacy of combined trabeculotomy and cataract surgery in lowering intraocular pressure (IOP) and improving visual acuity in adults with primary open-angle glaucoma (POAG). PATIENTS AND METHODS: A consecutive series of 141 eyes with POAG or ocular hypertension was prospectively recruited. One hundred and five eyes with visual field defects were treated by trabeculotomy combined with phacoemulsification and intraocular lens implantation (TPI group), and 36 eyes without visual field defects underwent cataract surgery (PI group). Patients in both groups were followed for more than six months after surgery (578.1 ± 35.8 and 616.0 ± 58.5 days, respectively). The IOP reductions after surgery were compared between the groups to evaluate the effect of combined trabeculotomy and cataract surgery. Visual acuity and complication rate in the two groups were secondary outcomes. The success probabilities of both groups were evaluated by Kaplan-Meier life table analysis with the log rank test. RESULTS: A significant IOP reduction was observed in the TPI and PI groups up to three years and one year and six months after surgery, respectively; the magnitude of the reduction was significantly larger in the TPI group up to three years after surgery. The success probabilities of the TPI group for IOP control under 21, 17, and 15 mmHg were 95.8%, 58.7%, and 30.0%, respectively, three years after surgery; the success probabilities were significantly higher than those of the PI group. Of 105 eyes, 104 (99.0%) had visual acuity equal to or better than baseline acuity three months after combined trabeculotomy and cataract surgery. CONCLUSION: Combined trabeculotomy and cataract surgery normalizes IOP and improves visual acuity in adults with glaucoma and coexisting cataract.
