Closed globe refixation of the IOL-bag complex with the ab-externo 8-exit-4-point fixation technique

Area of Science:

• Ophthalmology
• Surgical Innovation
• Intraocular Lenses

Background:

• Intraocular lens (IOL) dislocation is a frequent complication requiring surgical management.
• Current practices often involve IOL removal due to suboptimal sulcus placement of foldable IOLs.

Purpose of the Study:

• To present a novel surgical technique for refixating dislocated intraocular lenses (IOLs) using quadrilateral sutures.
• To evaluate the efficacy of this technique for securing looped haptic IOLs in the ciliary sulcus.

Main Methods:

• A quadrilateral suture technique utilizing the haptic loops of looped haptic IOLs as eyelets.
• Refixation of IOLs at the ciliary sulcus, with or without the capsular bag complex.
• Employment of a closed globe maneuver to minimize ocular trauma.

Main Results:

• The described suture placement ensures good IOL centration and avoids lens tilt.
• The closed globe maneuver facilitates minimal ocular trauma.
• The technique promotes faster postoperative recovery.

Conclusions:

• Quadrilateral suture refixation is an effective method for managing dislocated looped haptic IOLs.
• This technique offers improved IOL centration and potentially faster visual rehabilitation.
• It represents a viable alternative to IOL explantation in specific cases.
