Background

Currently, ophthalmological surgeons prefer the technique “Iris fixation of IOL implant to the eye walls” for complicated cataract surgeries. However, this method needs big size surgical incision and also leads to some complications like damage to the iris, limitation of pupil reaction and glaucoma.

Sulcus transscleral intraocular lens (IOL) suture fixation is becoming the optimal option for the aphakic patients or for those patients whose eyes have insufficient capsule support to regain visual acuity. But the current fixation procedure has some complications during the surgery like luxation of IOL implant to the vitreous cavity. The post-surgical complications of this procedure include decentration and tilt of the IOL and the risk of intraocular haemorrhage. In order to avoid these complications, the suture has to penetrate exactly through the ciliary sulcus, and the IOL haptics have to be directed into the sulcus and secured tightly there, in order to provide for proper centration of the implanted IOL.

Technology Overview

To perform the above–described surgery and to achieve an optimal outcome following surgery is still a challenging task for cataract surgeons. The invention (new clip and new fixation procedure) is a novel approach to complicated cataract surgery. The novel fixation clip is a small (~3mm length) device that makes cataract surgical procedure easy. It will assist in the scleral fixation of haptics of a single piece and three piece IOL.

Benefits

This new device simplifies scleral fixation of dislocated PC IOLs and allows repositioning of dislocated and subluxated PC IOLs.
This device allows the stabilization of the IOL by preventing the rotation of the lens, which is important for toric IOL.
This device helps in positioning the IOL with a small suture incision.
This device allows the stabilization of the IOL by preventing the decentration and tilting of IOL. F
The duration of the surgery will be shorter by using this device.
