Single-string, closed-loop fixation modification to reposit a dislocated triple-looped haptic intraocular lens.

Area of Science:

• Ophthalmology
• Surgical Techniques
• Intraocular Lens Implantation

Background:

• Dislocation of intraocular lens (IOL)-capsular bag complexes presents a surgical challenge.
• Existing methods for repositioning dislocated IOLs may have limitations.

Purpose of the Study:

• To describe and evaluate a novel single-string, closed-loop fixation technique for repositioning dislocated triple-looped haptic IOL-capsular bag complexes.
• To assess the safety and efficacy of this technique in a clinical setting.

Main Methods:

• A retrospective study of 4 eyes from 4 consecutive patients undergoing the described technique.
• Utilized a guide needle with 10-0/8-0 polypropylene suture to pass through fenestrated haptics twice.
• Employed a scleral interlaminar course as the fixation point, creating intrascleral knots for secure IOL fixation.

Main Results:

• All 4 repositioned intraocular lenses (IOLs) were well-centered and stable throughout the follow-up period.
• No instances of suture erosion, hypotony, scleral atrophy, chronic inflammation, retinal tears, or detachments were observed.

Conclusions:

• The single-string, closed-loop fixation technique is a safe and effective method for managing dislocated IOL-capsular bag complexes.
• This technique offers stable IOL positioning and avoids common postoperative complications.
