Summary
The porous polyethylene multipurpose conical orbital implant is safe and effective for evisceration surgery. This orbital implant provides good prosthetic motility and cosmetic results for patients with blind painful eyes.
Area of Science:
- Ophthalmology
- Ophthalmic Surgery
- Biomaterials
Background:
- Evisceration is a surgical procedure for blind painful eyes.
- Orbital implants are used to maintain orbital volume and support prosthetic eyes.
- Porous polyethylene implants offer potential advantages in biocompatibility and integration.
Purpose of the Study:
- To evaluate the safety and efficacy of a novel porous polyethylene multipurpose conical orbital implant.
- To assess outcomes following evisceration using this specific implant design.
Main Methods:
- Retrospective review of 31 patients undergoing evisceration with the multipurpose conical orbital implant.
- Post-operative evaluation at 1 week, 1 month, and 6 months.
- Assessment of implant exposure, superior sulcus deformity, and prosthetic motility.
Main Results:
- No cases of implant extrusion, migration, or infection were reported.
- Excellent prosthetic motility and cosmetic results were achieved in all patients.
- A low incidence of complications: 3% implant exposure and 3% superior sulcus deformity.
Conclusions:
- The porous polyethylene multipurpose conical orbital implant is a safe and effective option for evisceration.
- It provides good functional (motility) and aesthetic outcomes.
- This implant represents a viable solution for managing blind painful eyes.
