Lens implant surgery in pars planitis.

Abstract

Intraocular lens (IOL) implantation is usually contraindicated in eyes with active inflammation, but patients with "burned-out" pars planitis also may be considered as candidates. Fifteen of 16 eyes in eight patients underwent extracapsular cataract extraction (ECCE) with posterior chamber IOL (PC IOL) implantation combined with pars plana vitrectomy for both cataracts and chronic cystoid macular edema (CME); 60% achieved visual acuity of 20/40 or better. Even with "low-grade" inflammation in these patients, however, a persistent veil of debris accumulated over the posterior and anterior surface of the IOL. One patient (patient 2) required 27 YAG procedures for two eyes, and another required 11 YAG procedures and eventual removal of the IOL. Another patient required surgical "brushing-off" of the IOL and vitrectomy. Even in eyes with "burned-out" uveitis, a continual low-grade inflammation may complicate the use of IOL implantation.
