In the past few years we have seen many advances in IOL fixation using techniques described by Yamane, Canabrava, Oetting, and others. This involve creating a flange using cautery on the tip of a haptic or suture end. These allow secure fixation of the haptic or suture within a scleral needle track. The key to these techniques is to ensure that the flange is tucked within the scleral and not simply sitting on top of it. If this plastic flange is directly under the conjunctiva it may erode through and cause problems. This video explains it very well with intra-operative OCT scans.
