Abstract
A simplified intrascleral fixation technique involving implantation of the Carlevale intraocular lens (IOL) in the posterior chamber is described, which lodges the T-shaped IOL haptics in the scleral wall, not requiring scleral flaps. This surgical modification reduces operative time, limits iatrogenic damage to the sclera, and avoids friction between haptics and the conjunctiva, which may cause conjunctival erosion and infection in the long term. 13 patients with crystalline lens or IOL dislocation/subluxation had surgery to implant the Carlevale IOL in the posterior chamber. Mean corrected distance visual acuity preoperatively was 0.75 ± 0.5 logMAR (range, 0.2 to 1.5 logMAR) and improved to 0.28 ± 0.3 logMAR (range, 0 to 1.0 logMAR) postoperatively. Complications rarely occurred and were not sight-threatening. The sutureless scleral fixation of the Carlevale IOL using the modified surgical technique may represent a safe and effective procedure to restore visual function in patients with damaged zonular-capsular support.
