Two-string technique to manage dislocated posterior chamber plate-haptic intraocular lens

Area of Science:

• Ophthalmology
• Surgical Techniques
• Intraocular Lenses

Background:

• Dislocation of posterior chamber intraocular lenses (PC IOLs) can occur, necessitating intervention.
• Management options for dislocated PC IOLs traditionally include lens removal or exchange.
• Plate-haptic foldable collamer PC IOLs present unique challenges when dislocated.

Purpose of the Study:

• To describe a novel technique for the repositioning and transscleral fixation of a dislocated plate-haptic foldable collamer PC IOL.
• To provide an alternative surgical approach to avoid IOL explantation or replacement.
• To detail the specific steps involved in the transscleral fixation procedure.

Main Methods:

• The dislocated PC IOL was repositioned from the anterior chamber.
• A double-armed suture on a curved needle was used for fixation.
• Scleral fixation was performed at specific clock hours (10:30, 4:30, 7:30) passing through the superior haptic eyelet and mirroring the path for the inferior haptic.

Main Results:

• Successful repositioning and transscleral fixation of the dislocated PC IOL were achieved.
• The described technique allowed for secure placement of the IOL without removal.
• The fixation method provided stable positioning through symmetrical suture placement.

Conclusions:

• The described transscleral fixation technique is a potentially useful alternative for managing dislocated plate-haptic foldable collamer PC IOLs.
• This method may offer a less invasive approach compared to IOL exchange or removal.
• Further studies may be warranted to evaluate the long-term outcomes and efficacy of this technique.
