PURPOSE To describe endoscope-assisted Carlevale intraocular lens (IOL) implantation. METHODS Twelve eyes underwent posterior vitrectomy combined with Carlevale IOL implantation and endoscopy in a single procedure, using a technique developed by the authors. Transscleral incisions were performed under direct visualization of the sulcus using the endoscope, and the final lens position was checked at the end of each intervention. The main outcome was to determine the exact position of all lens fixation points. RESULTS All plugs were correctly placed in the sulcus, but in seven eyes (58.3%) at least one of the closed-loop haptics was folded over the ciliary body. Repositioning was performed during the same procedure. Given that each IOL has four closed-loop haptics, the incidence of this complication was 23% (11/48). CONCLUSIONS Blind implantation of Carlevale IOL may cause a high incidence of haptic malpositioning. Because the sulcus and the ciliary body are not visible under the microscope, endoscopy is the only way to ensure correct lens implantation. This new technique ensures that all lens fixation points are correctly placed by the end of surgery, avoiding complications like decentration or tilting of the IOL, damage to the iris or the ciliary body, and uveitis.
