PURPOSE: To describe a haptic-bending adjustment technique for correcting persistent posterior intraocular lens (IOL) tilt after flanged intrascleral fixation and to evaluate its anatomical and optical outcomes.
METHODS: This retrospective case series included four eyes with symptomatic postoperative IOL tilt following flanged intrascleral fixation. The haptics were first shortened and re-flanged, and an additional bend was created approximately 1 mm proximal to the haptic tip on the side corresponding to the posterior tilt. IOL tilt was quantified using Scheimpflug imaging, and refractive outcomes were analyzed using power-vector analysis of manifest refraction.
RESULTS: Patient age ranged from 32 to 63 years, with a mean operative time of 25.5 ± 8.23 minutes. IOL tilt decreased from 6-8° to 2-4° and remained stable during follow-up. All eyes showed improved visual acuity and reduced refractive astigmatism without change in corneal astigmatism. No intraoperative complications, recurrent tilt, or reoperations occurred.
CONCLUSIONS: Haptic bending combined with haptic shortening may provide a feasible option for correcting posterior IOL tilt after flanged intrascleral fixation without creating new scleral tunnels or exchanging the IOL.
