# Add-on implantation of the smaller-incision new generation implantable miniature telescope (SING IMT™) in pseudophakic eyes

## TL;DR

A new surgical method implants a miniature telescope in pseudophakic eyes to improve vision in advanced macular degeneration patients.

## Contribution

A novel add-on sulcus implantation technique for SING IMT™ in pseudophakic eyes is introduced and shown to be feasible.

## Key findings

- Surgical implantation was uneventful with stable device positioning and no major complications.
- Visual acuity improved by 3–4 ETDRS lines with enhanced daily visual function reported.
- Corneal endothelial loss remained under 5% at six months post-surgery.

## Abstract

To describe a novel surgical technique for add-on sulcus implantation of the Smaller-Incision New Generation Implantable Miniature Telescope (SING IMT™) in pseudophakic eyes with end-stage age-related macular degeneration (AMD).

Two pseudophakic patients with bilateral end-stage AMD underwent add-on SING IMT™ implantation in the ciliary sulcus. Pre- and postoperative evaluations included best-corrected distance visual acuity (BCDVA), anterior segment OCT (AS-OCT), corneal endothelial cell counts, and subjective visual function assessments, with follow-up to 6 months.

Both surgeries were uneventful. The devices remained stable and well-centered with no significant inflammation, corneal decompensation, or intraocular pressure elevation. BCDVA improved by 3–4 ETDRS lines, and both patients reported improved daily visual function. Corneal endothelial loss was < 5% at 6 months.

Add-on sulcus implantation of the SING IMT™ in pseudophakic eyes is surgically feasible and well tolerated, expanding the potential indications of this visual rehabilitation device to a broader AMD population.
