Cyclodialysis Cleft After Secondary Intraocular Lens Placement With Yamane Technique

Purpose:The purpose of this study was to report a rare case of cyclodialysis cleft after secondary intraocular lens (IOL) placement using the Yamane flanged intrascleral haptic fixation technique.Methods:This study is an observational case report.Results:A 74-year-old man with an ocular history of spontaneously dislocated IOL and subsequent anterior chamber IOL (ACIOL) placement presented with monocular diplopia secondary to ACIOL subluxation. The patient underwent explantation of the subluxed ACIOL and placement of a scleral-fixated IOL using the Yamane technique. The postoperative course was complicated by persistent hypotony, prompting ultrasound biomicroscopy, which revealed a cyclodialysis cleft adjacent to one of the externalized IOL haptics. The haptic was discovered in the involved supraciliary space while performing direct cyclopexy. The cyclodialysis cleft closed with return to physiologic intraocular pressure.Conclusions:Cyclodialysis cleft formation is a possible complication of scleral IOL fixation and should be suspected in cases of prolonged postoperative hypotony. Extended longitudinal tracking of the needle and haptic through the supraciliary space may be one mechanism for cyclodialysis cleft formation in the Yamane technique.
