Phacoemulsification and intraocular lens implantation for angle closure glaucoma after the relief of pupillary block.
OBJECTIVE
We 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
Department of Ophthalmology, National Nagasaki Medical Center, Nagasaki, Japan.


METHODS
Eighteen eyes from 15 patients after laser iridotomy (17 eyes) or peripheral iridectomy (1 eye) had undergone surgery and were studied. We used an iris retractor in 7 eyes due to insufficient mydriasis and a capsular tension ring in 2 eyes due to phacodonesis during the operation. The patients were followed up for at least 6 months (13.8 +/- 7.2 months; range: 6-36 months).


RESULTS
The mean IOP significantly decreased from 17.4 +/- 8.1 to 13.5 +/- 3.3 mm Hg at 6 months after surgery. The IOP was below 21 mm Hg in all eyes. The visual acuity was not worsened in any eyes and became better than 2 Snellen lines in 14 eyes. The corneal endothelial cell count decreased from 2,365 +/- 517 to 1,960 +/- 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, we should take care of operative complications because of a shallow anterior chamber, poor mydriasis and zonular weakness.
