A free orbital fat graft may be an easy and effective method to prevent orbital implant exposure in patients requiring enucleation for retinoblastoma, according to a study.

Nam Ju Kim, MD, and colleagues performed free orbital fat grafts after enucleation and implantation of Porex Medical’s Medpor porous polyethylene orbital implant in 39 eyes. Results were compared with 38 eyes that underwent conventional enucleation and Medpor implantation without an orbital fat graft.

Implant exposure occurred in 13 of the 39 eyes that had conventional enucleation and implantation and in none of the eyes that underwent free orbital fat grafts.

The study is published in the July issue of Ophthalmic Plastic and Reconstructive Surgery.
