In office management of optic capture of scleral fixated posterior chamber intraocular lenses.

ABSTRACT

INTRODUCTION: Optic capture of sutured scleral fixated posterior chamber intraocular lenses (PC IOLs) is an occasional complication resulting in blurred vision and discomfort. METHODS: A retrospective study of the management of 18 eyes (3.6%) with optic capture out of 495 eyes with scleral fixated IOLs during the study period. 54 procedures were performed in the management of optic capture of sutured scleral fixated PC IOLs. An in-office technique was utilized to relieve the optic capture by repositioning the optic posterior to the iris. This technique was performed after topical anesthesia and topical 5% betadine with the patient stably positioned at the slit lamp. Using a 30-gauge needle, sometimes after a 15-degree paracentesis blade, the needle was advanced in a parallel plane above the iris until the tip reached the edge of the captured optic. The optic is engaged in the inferior periphery away from the central visual axis, and pushed gently posteriorly just enough to reposition the optic posterior to the iris. In some cases, pilocarpine 2% drops were utilized after the procedure to decrease the risk of recapture of the optic. RESULTS: All 54 procedures were successfully performed in the office without significant pain or discomfort. Vision before optic capture, during optic capture, and at the first office visit after optic capture were comparable. There were not any cases of endophthalmitis, hyphema, iris trauma, iris prolapse or keratitis. While eight patients only had one episode of optic capture, 10 patients had multiple episodes of optic capture, all managed with this in office procedure. Recurrent optic capture occurred more frequently in eyes with fixation at less than 2 mm from the limbus than eyes with scleral fixation at 2 mm from the limbus. CONCLUSION: Reposition of the optic after pupillary capture of a scleral fixated PC IOL can be successfully performed in the office without discomfort or significant complications and is an alternative management option to a return to the operating room. This procedure may be especially important when there is poor access to the operating room or restricted access to the operating room as during the COVID19 pandemic.
