Summary
Implantable collamer lens (ICL) dislocation is rare, occurring in 0.072% of cases. While repositioning surgery is effective for ICL dislocation, potential retinal complications require careful monitoring.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Medical Device Complications
Background:
- Implantable collamer lens (ICL) surgery is a popular refractive procedure.
- Understanding the incidence and outcomes of ICL dislocation is crucial for patient safety.
Purpose of the Study:
- To investigate the incidence, patient demographics, and postoperative prognosis of implantable collamer lens (ICL) dislocation.
- To identify causes and complications associated with ICL dislocation and repositioning surgery.
Main Methods:
- Retrospective review of ICL dislocation cases from four major Japanese refractive surgery centers until December 2019.
- Analysis of incidence, patient background, causes of dislocation, repositioning surgery complications, and visual outcomes.
Main Results:
- Seven cases of ICL dislocation were identified (0.072% of 9775 eyes) at an average of 28.6 months postoperatively.
- All affected patients were male; common causes included sports injuries and blunt ocular trauma.
- Two patients experienced re-dislocation, and one developed retinal detachment after repositioning surgery.
Conclusions:
- ICL dislocation is a rare complication following implantable collamer lens surgery.
- Repositioning surgery is an effective treatment for ICL dislocation.
- Retinal complications, such as detachment, can occur post-repositioning surgery, necessitating vigilant follow-up.
