Summary
Hydroxyapatite orbital implants offer excellent prosthesis motility and cosmetic results after enucleation for eye cancer. This study found few complications in pediatric and adult patients, with no adverse effects on cancer treatment or monitoring.
Area of Science:
- Ophthalmology
- Oncology
- Biomaterials Science
Background:
- Hydroxyapatite orbital implants are a recent innovation for post-enucleation prosthesis motility.
- Limited data exists on their use in patients with intraocular malignant neoplasms.
Purpose of the Study:
- To evaluate the safety and efficacy of hydroxyapatite orbital implants in patients enucleated for malignant intraocular tumors.
- To assess complications, motility, and impact on cancer management.
Main Methods:
- Hydroxyapatite orbital implantation in approximately 200 patients (infants to adults) undergoing enucleation for intraocular tumors.
- Median follow-up of 24 months.
Main Results:
- No orbital hemorrhage, infection, extrusion, or migration occurred.
- Three cases of conjunctival erosion were successfully repaired.
- Excellent socket motility and prosthesis cosmetic satisfaction were achieved.
- No adverse effect on tumor course or postoperative surveillance.
Conclusions:
- Hydroxyapatite orbital implants are well-tolerated in pediatric and adult patients with a history of intraocular malignancy.
- The implant provides improved prosthesis motility with a low complication rate.
- It does not interfere with oncologic management or follow-up.
