We thank Patel and colleagues for their interest in our study.1 In our article, we did not report the number of patients who had lost 2 or more Snellen lines of visual acuity as this will be examined as part of future work looking at surgical outcomes such as visual acuity and intraocular pressure. We had 1 patient who lost vision completely after contracting severe endophthalmitis. There were no cases of devastating suprachoroidal hemorrhage or wipeout syndrome leading to complete loss of vision during the 1-year period. The aim of our article was to mainly investigate complication and reoperation rates between the 2 groups of patients with primary angle-closure glaucoma and primary open-angle glaucoma. The incidence of cataract development in our study was also not reported as it is well accepted that trabeculectomy can induce cataract formation2,3; furthermore, we were comparing phacotrabeculectomy with trabeculectomy as part of our analysis.
