Summary
A novel vitreoretinal technique successfully repositions dislocated acrylic posterior chamber intraocular lenses (PCIOL), ensuring stable sulcus fixation and improved visual acuity in most patients. This method offers a viable solution for dislocated PCIOLs.
Area of Science:
- Ophthalmology
- Vitreoretinal Surgery
- Intraocular Lens Implantation
Background:
- Dislocation of posterior chamber intraocular lenses (PCIOL) can compromise visual function.
- A novel vitreoretinal surgical technique is presented for managing dislocated 1-piece acrylic PCIOLs.
Purpose of the Study:
- To describe a new vitreoretinal technique for repositioning dislocated 1-piece acrylic PCIOLs.
- To evaluate the outcomes and efficacy of this repositioning method.
Main Methods:
- Retrospective analysis of 7 eyes with dislocated 1-piece acrylic PCIOLs.
- Vitreoretinal surgery involving temporary haptic externalization and suture fixation in the ciliary sulcus using polypropylene sutures.
Main Results:
- All 7 repositioned PCIOLs achieved stable sulcus fixation with good visual outcomes (median BCVA improved from 20/70 to 20/40).
- One case required IOL exchange due to complications; mild IOL tilting occurred in one eye without affecting fixation.
- Capsular defect was identified as the cause of dislocation in all cases.
Conclusions:
- The described vitreoretinal technique provides secure sulcus fixation for dislocated all-acrylic PCIOLs, preventing suture slippage.
- Proper suture placement ( >1 mm from limbus) is crucial to avoid iris chafing and ensure optimal outcomes.
