The iris perforations remained open in follow-ups of 1 week to 8 months, and pupil block was relieved. The technique involved was described. The common complications included slight local opacity in the peripheral cornea, mild iris hemorrhage, and postoperative hypertensive response in IOP, all of which did not affect the visual acuity.
