• Fifty eyes of 40 patients with glaucoma underwent extracapsular cataract extraction with posterior chamber lens implantation. Their visual results and early postoperative complications were compared with those of eyes in an agematched group of patients without glaucoma after the same procedure. Substantial increases in early postoperative intraocular pressure (IOP) occurred in 62% of the glaucomatous eyes and in only 10% of the normal eyes. The level of best visual acuity was slightly worse (20/40) on average in the glaucomatous eyes than in the nonglaucomatous eyes (20/25). At six months after surgery, 82.5% of the nonfiltered glaucomatous eyes needed the same number of or additional glaucoma medications to maintain an IOP of less than 20 mm Hg. Ten of the glaucomatous eyes underwent trabeculectomy along with cataract surgery due to inadequate IOP control while the patient was receiving maximum medical therapy. Control was substantially improved, with 100% of these patients receiving the same number of or fewer medications at six months. By one year, only 30% of these patients required the same number of medications postoperatively as preoperatively, but all had IOP control.
