New approach uses polypropylene suture for four-point scleral fixation of secondary IOL
Visual rehabilitation in aphakia and malpositioned IOLs often requires surgical intervention with secondary IOL implantation. In addition, subluxated and dislocated IOLs may require repositioning or exchange. IOL exchange can be performed using various surgical approaches, including an anterior chamber IOL, iris-fixated IOL, sulcus-fixated IOL or scleral-fixated IOL. Scleral-fixated IOLs can be foldable or nonfoldable, using two-point or four-point fixation. Foldable lenses provide small entry wound size, and four-point fixation, unlike two-point fixation, decreases IOL tilt and increases IOL
