Phakic malignant glaucoma was seen in five eyes of four patients: it occurred in four eyes after trabeculectomy and in one eye after peripheral iridectomy. They were treated by anterior pars plana vitrectomy combined with intracapsular lens extraction through a corneal incision. In all eyes the anterior chamber regained its normal depth, and the intraocular pressure could be controlled by medical treatment in three eyes. The remaining two eyes required further filtering procedure and subsequently the intraocular pressure was controlled by medical treatment. No serious complications were encountered throughout the postoperative follow-up period of 7-26 months.
