Recurrent Iris Capture after Iris Suturing following Scleral-Sutured Intraocular Lens Fixation: A Case Report

Capture of the intraocular lens (IOL) optic by the iris or pupillary margin is defined as iris capture, and this postoperative complication occurs after scleral-sutured IOL fixation and sutureless intrascleral fixation. However, the optimal placement of iris sutures for preventing recurrence has yet to be adequately described.

We report on the case of a 72-year-old man with ocular hypertension 1 year after scleral-sutured IOL fixation in the left eye who was referred for iris capture. Although topical medication was initially used to relieve the iris capture, it later became refractory. Iris suturing was initially performed at the 12 and 6 o'clock positions. However, at 1 month postoperatively, recurrent iris capture was subsequently observed. As a result, a second iris suturing procedure centered at the 8 o'clock position was performed at the documented capture site. In this second iris suturing procedure, which is shown in the online supplementary intraoperative video, an additional suture was placed at the documented 8 o'clock capture site. The clinical course has remained favorable and there has been no recurrence observed.

Current results suggest that iris suturing is an effective treatment option for recurrent iris capture after scleral-sutured IOL fixation. Moreover, further recurrence may be prevented by utilizing suture placement guided by the documented site of recurrence.
