Reduction of pupillary constriction during cataract surgery using suprofen.

The efficacy of a new nonsteroidal anti-inflammatory agent, suprofen, for reducing pupillary constriction during cataract surgery was ascertained in a double-masked, multicenter, clinical study. Prior to surgery 1.0% suprofen or a placebo was instilled; the surgeon's normal regimen of mydriatics and cycloplegics was used.

Argon laser debridement of the posterior capsule: a potential treatment for posterior capsule opacification after extracapsular cataract surgery.

We treated an opacified membrane on the anterior surfaces of the posterior capsule of two cynomolgus monkeys that had undergone extracapsular cataract extraction and intraocular lens insertion. After development of opacification of the posterior capsule, argon laser energy was employed in an attempt to debride the capsules while maintaining structural integrity of the capsule. With this technique, small areas of destruction of the membrane on the anterior surface of the posterior capsule were created with preservation of the capsule.

Management of the posterior capsule before and after the YAG laser.

A retrospective chart review of 2,514 consecutive posterior chamber implants was carried out to assess the management of the posterior capsule when vision loss dictated intervention. The capsulotomy technique used between May 1977 and March 1983 was pars plana posterior capsulotomy (227 eyes). All posterior capsulotomies performed after April 1, 1983 were with the YAG laser (342 eyes).

Cystoid macular edema in pseudophakia.

Cystoid macular edema after cataract surgery, with or without intraocular lens implantation, has been reported to develop in more than 50% of patients as detected by fluorescein angiography. It is associated with reduced visual acuity in up to 8% of cases. Analysis of ongoing clinical trials at the Wilmer Institute indicates that clinically significant cystoid macular edema develops in a lower percentage of cases (2% total incidence and 0.
