Abstract: The Smaller-Incision New-Generation Implantable Miniature Telescope (SING IMT) is an IOL designed to enhance central vision in patients with bilateral late-stage AMD. This report describes a case of successful surgical repositioning of a tilted SING IMT following haptic displacement out of the capsular bag A 77-year-old man with bilateral geographic atrophy and baseline CDVA (Corrected Distance Visual Acuity) of logMAR 0.96 (Snellen 20/200) underwent uncomplicated implantation of a SING IMT in the right eye. Six weeks postoperatively, CDVA showed no improvement, and the patient reported monocular diplopia with off-axis visual perception. Retinal morphology remained stable. Slit-lamp and anterior segment OCT revealed pronounced optic tilt caused by inferior haptic dislocation out of the capsular bag. The haptic was successfully repositioned by performing superior traction with a push-pull hook, resulting in restoration of straight, diplopia-free vision and an improvement in CDVA to logMAR 0.52 (Snellen 20/63). Prompt surgical correction of haptic displacement may fully restore the optical and functional benefits of the SING IMT without compromising corneal health. • The SING IMT enhances central vision in late-stage AMD • Haptic dislocation of telescopic IOLs is a rare but visually significant complication • In this case, inferior haptic dislocation led to optic tilt and off-axis visual symptoms • Surgical repositioning fully restored the device’s alignment and intended function • Endothelial health was preserved following the secondary intervention
