Changing trends in explanted intraocular lenses: a single center study.
Journal of Cataract and Refractive Surgery
|September 11, 1992
Summary
This study analyzed 1,091 explanted intraocular lenses (IOLs). Closed-loop anterior chamber lenses were most common, but removal rates for other IOL styles are increasing.
Area of Science:
- Ophthalmology
- Medical Device Analysis
- Surgical Outcomes
Background:
- Intraocular lens (IOL) explantation is a significant surgical procedure.
- Understanding trends in IOL explantation is crucial for patient safety and surgical practice.
- Long-term outcomes of various IOL designs require ongoing evaluation.
Purpose of the Study:
- To analyze the types and trends of intraocular lenses explanted over a nine-year period.
- To identify specific IOL models with higher explantation rates.
- To investigate reasons for late explantation, such as suture breakage.
Main Methods:
- Retrospective review of 1,091 explanted intraocular lenses.
- Categorization of explanted lenses by type and model.
- Analysis of explantation trends over time and investigation of specific complication events.
Main Results:
- Closed-loop anterior chamber lenses constituted 58.6% of explantations.
- Stableflex lenses represented 28.8% of all removed lens types.
- Increasing explantation rates were observed for older iris-fixated and rigid anterior chamber lenses, with late suture breakage noted in five cases (average 112 months post-implantation).
Conclusions:
- While closed-loop anterior chamber lenses were most frequently explanted, other IOL styles show rising removal rates.
- Late complications, including suture breakage in iris-fixated lenses, necessitate continued monitoring of older IOLs.
- These findings highlight the importance of long-term surveillance for intraocular lens performance and safety.
