Background:
To report a new technique for iris capture of the posterior chamber intraocular lens (IOL) implanted in patients with a posterior capsule defect.
Methods:
In this retrospective case series, a rectangular loop ciliary body suture technique was performed to rectify iris capture. The suture passes between the IOL and iris in a direction perpendicular to the iris edge capturing the IOL.
Results:
A total of three IOLs with iris capture underwent a rectangular loop suture technique. No recapture was observed postoperatively. In one case, large astigmatism appeared after the surgery but recovered at 1 month post operation. No further complications were found.
Conclusions:
The rectangular loop suture technique is an effective, convenient, and minimally invasive method for iris capture of the IOL.
