Simplified and safe method of sutureless intrascleral posterior chamber intraocular lens fixation: Y-fixation technique

Abstract

We report a new surgical technique that allows intrascleral fixation of a posterior chamber intraocular lens (IOL) without sutures. The Y-fixation technique does not involve complicated intraocular manipulation and achieves safe sutureless fixation. A Y-shaped incision is made in the sclera and a 24-gauge microvitreoretinal (MVR) knife is used to create the sclerotomy instead of a needle. The Y-shaped incision eliminates the need to raise a large lamellar scleral flap and to use fibrin glue because the haptic can be fixed both inside the tunnel and in the groove, and performing the sclerotomy with the 24-gauge MVR knife simplifies extraction of the haptic and improves wound closure. There is no risk of infection from exposure of the haptic on the sclera and no use of fibrin glue. There was significantly less IOL decentration and tilt than with suture fixation.
