# New minimally invasive technique for repositioning of a subluxated retropupillary iris-claw IOL using needle-assisted fixation

## TL;DR

A new minimally invasive method using three needles successfully repositions subluxated retropupillary iris-claw IOLs, offering faster recovery and fewer complications.

## Contribution

A novel, needle-assisted reenclavation technique for subluxated retropupillary iris-claw IOLs without trocars or sutures.

## Key findings

- The technique was successfully performed on four patients with subluxated IOLs.
- All patients regained baseline visual acuity with no post-operative complications over six months.
- The method reduces operative time and surgical manipulation, enhancing recovery and safety.

## Abstract

This paper presents a modification of the needle-assisted retropupillary fixation technique for iris-claw intraocular lenses (IOLs). We introduce a novel, minimally invasive reenclavation technique for managing subluxated retropupillary iris-claw IOLs.

The technique was successfully performed on four patients diagnosed with subluxated retropupillary iris-claw IOLs. This approach involved a novel, minimally invasive reenclavation technique that utilized three needles: one long, straight translimbal needle crossing the anterior chamber and two needles introduced through the pars plana to reposition and securely reenclavate the IOL.

All patients experienced immediate and significant visual recovery, with their baseline visual acuities reestablished postoperatively. Importantly, no post-operative complications were observed during the six-month follow-up period, highlighting the safety and efficacy of the technique.

Our novel, minimally invasive technique for reenclavation of iris-claw IOLs, employing just three needles, eliminates the need for trocar insertion, infusion cannulas, or sutures. This approach offers significant advantages, including a shorter operative time and minimal surgical manipulation, leading to faster patient recovery and fewer complications.
