Haptic exposure is a rare complication of intrascleral haptic fixation (ISHF) that can lead to intraocular lens (IOL) tilt, significant astigmatism, and increased infection risk. We describe a novel technique for managing haptic erosion using a superficial scleral tunnel and scleral patch graft. A 69-year-old man presented with nasal haptic exposure in the left eye, accompanied by significant IOL tilt and 5 diopters of astigmatism. Surgery was completely extraocular without requiring any intraocular maneuvers and involved creating a partial-thickness scleral tunnel to embed the exposed haptic, securing it with a 10-0 nylon suture, and covering the site with a scleral patch graft. Postoperatively, visual acuity improved from 20/80 to 20/20, with resolution of IOL tilt and improved refractive result (+0.50 −0.75 × 119). At 4 months, the surgical site remained stable, and the patient expressed high satisfaction. This technique provides a minimally invasive, effective solution for addressing haptic exposure while preserving IOL stability and visual outcomes.
