Summary
This study presents a new surgical method for fixing dislocated polymethylmethacrylate (PMMA) intraocular lenses (IOLs) with eyelets. The minimally invasive technique effectively improved vision and stabilized IOLs without major complications.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Ophthalmic Devices
Background:
- Dislocation of scleral-sutured polymethylmethacrylate (PMMA) intraocular lenses (IOLs) with eyelets can impair vision.
- Existing refixation methods may be invasive or have limitations.
Purpose of the Study:
- To describe a modified, minimally invasive technique for the internal refixation of dislocated scleral-sutured PMMA IOLs with eyelets.
- To evaluate the efficacy and safety of this novel surgical approach.
Main Methods:
- A three-port pars plana vitrectomy was performed.
- A 30-gauge needle with an 8-0 polypropylene suture was used for internal fixation through the scleral site.
- A flapless intrascleral knotting technique was employed for suture burial.
Main Results:
- Six eyes of six patients were successfully treated.
- All patients showed significant improvement in uncorrected visual acuity post-surgery.
- IOLs remained stable with proper centration, and no major complications were observed during 6-12 months of follow-up.
Conclusions:
- The modified technique provides an effective and minimally invasive surgical alternative for refixing dislocated scleral-sutured PMMA IOLs with eyelets.
- This approach offers good visual outcomes and IOL stability with a low complication rate.
