In the past, glaucoma has been considered a relative contraindication to the use of an intraocular lens (IOL) in a patient undergoing cataract extraction. In this study, we examined postoperative intraocular pressure (IOP) control for three months postoperatively in 46 eyes with glaucoma undergoing cataract extraction with implantation of a posterior chamber IOL. Twenty-six eyes or 56.5% could be classified as having improved IOP control three months postoperatively. At the same time, 19 eyes or 41.3% demonstrated the same IOP control after lens implantation. Thus, 45 of the total of 46 eyes had as good or better postoperative IOP control. Of the 46 eyes, 100% required preoperative glaucoma medication, while postoperatively only 41% required medication.
