Wang et a? should be commended for their effort to investigate the effects of phacoemulsification on the intraocular pressure (IOP) and ultrasound biomicroscopic image of filtering bleb in eyes with cataract and functioning filtering blebs. UBM is a good method used worldwide to observe the internal structure of filtering blebs.2 IOP is important for evaluating the filtering function of the eyes with filtering blebs. However, Wang et al claim that, unlike our results,3 the IOP increased after phacoemulsification at each follow-up visit.In the discussion, Wang et al compared their results with the studies of Klink et al4 and Rebolleda et al.5 In all, 70.4% of the patients in Wang's study were those with angle closure glaucoma compared with no patient in Klink's study and only 6 of the 49 patients in Rebolleda's study. Comparison of different types of glaucoma may make their study underpowered and of limited value.We noticed in Wang's study that the IOP before phacoemulsification ranged from 4.0 to 19.7 mm Hg.
