PURPOSE: The authors studied the surgical outcomes of phacoemulsification and intraocular lens (IOL) implantation for cataract and/or uncontrolled intraocular pressure (IOP) in eyes with angle closure glaucoma. METHODS: Eighteen eyes of 15 patients after laser iridotomy (17 eyes) or peripheral iridectomy (one eye) had undergone surgery and were studied. The authors used an iris retractor in seven eyes due to insufficient mydriasis and a capsular tension ring in two eyes due to phacodonesis during the operation. The patients were followed up for at least six months (13.8 ± 7.2 months; range, 6-36 months). RESULTS: Mean IOP significantly decreased from 17.4 ± 8.1 to 13.5 ± 3.3 mmHg at six months after surgery. IOP was below 21 mmHg in all eyes. The visual acuity had not worsened in any eyes and became better than two Snellen lines in 14 eyes. The corneal endothelial cell count decreased from 2365 ± 517 to 1960 ± 661/mm2 (18.3 ± 17.2%). CONCLUSIONS: Phacoemulsification and IOL implantation is useful in IOP control for angle closure glaucoma after relief of pupillary block. However, care should be taken regarding operative complications because of a shallow anterior chamber, poor mydriasis and zonular weakness.
