Extrusion of haptic is a rare complication after intra-scleral haptic fixation of intraocular lens (SF-IOL). Various techniques described for its management such as autologous scleral patch, cauterization of exposed haptic, reattempting the glued IOL and IOL explant have their own limitations. Presently, we describe a simple rescue technique for management of such situations. In this method, after performing localized conjunctival peritomy, 2 mm long partial-thickness scleral tunnel is fashioned with an angled 20-guage microvitreoretinal blade 1.5 mm away from the limbus in line with pre-existing defective scleral flap underneath which the exposed haptic is tucked securely. Following this, conjunctival autograft (CAG) with fibrin glue application is undertaken to combat conjunctival fibrosis. In three patients, where this technique was performed, had well-tucked haptic and maintained visual acuity with no complications at 3-months follow-up. This technique is a useful method of tucking extruded haptic after SFIOL in eyes subjected to multiple previous surgeries.
