BLOG: Peripheral iridectomy for glued IOL in large eyes
Click Here to Manage Email Alerts
The most important limiting factor in glued IOL fixation is the limited amount of haptic externalized in large eyes. Inadequate haptic tuck into the scleral pockets can lead to unstable IOL fixation. Anterior sclerotomy is often performed for large eyes, shifting the IOL plane anteriorly to allow less distance to be traversed by the haptics, thereby facilitating greater haptic length exteriorization. In this endeavor, the iris is often damaged during the procedure of creating an anterior sclerotomy. Performing a peripheral iridectomy at the proposed site of an anterior sclerotomy can prevent this complication because the needle does not tend to hit the base of the iris as during anterior sclerotomy.
