Summary
This review of Medallion intraocular lens (IOL) implantation found few late complications directly linked to the IOL itself. While nylon sutures deteriorated, IOL dislocations were rare, indicating good long-term safety.
Area of Science:
- Ophthalmology
- Biomaterials Science
Background:
- The Medallion intraocular lens (IOL) was implanted in numerous patients.
- Long-term outcomes and potential complications require thorough investigation.
Purpose of the Study:
- To evaluate the late complications associated with Medallion IOL implantation.
- To assess the long-term safety and performance of this specific intraocular lens.
Main Methods:
- A retrospective review of 90 cases with Medallion IOLs.
- Analysis of cases with a minimum five-year follow-up period.
- Documentation of all late complications and their relation to the IOL.
Main Results:
- Most late complications were not directly caused by the Medallion IOL.
- Progressive deterioration of nylon iris-lens sutures was observed over time.
- Late IOL dislocations were infrequent; however, two cases showed iris erosion.
Conclusions:
- The Medallion IOL demonstrated a favorable safety profile with few IOL-related late complications.
- Nylon suture degradation is a potential long-term issue, independent of IOL presence.
- Excluding early cases with guarded prognoses would have improved overall visual outcome statistics.
