Abstract: We developed intraocular lens (IOL) fixation procedure that only uses one suture during Zinn’s zonule dialysis portion of the combined surgery for IOL intracapsular fixation and unilateral loop suture for preserving the lens capsule. We treated 15 eyes in 15 patients which were confirmed to have almost 180° zonular dialysis during cataract surgery. After removing the lens, a scleral flap was created on the dialysis side. A straight needle for suturing was then inserted into the anterior chamber from the opposite side of the dialysis. The needle was used to attach the equatorial segment of the capsule on the dialysis side from the inside to the outside and then pull the suture thread under the scleral flap. After the thread was bound to a preceding loop of IOL, the IOL was inserted into the bag. Our procedure was found to be simple and less invasive, as our technique required no vitrectomy to be performed.
