A hydroxyapatite orbital implant was used after enucleation of an eye from a 5-year-old performance horse. A custom-made corneoscleral prosthesis was made and fitted over the hydroxyapatite implant. The implant and surgery were well tolerated. Placement of a cosmetic prosthesis is desired after enucleation of equine eyes to allow horses to return to competition. Synthetic spheres consisting of methylmethacrylate or silicone have been used, although reported complications have included extrusion, infection, and poor cosmetic results. Hydroxyapatite orbital implants made from marine coral allow vascular and fibrous tissue growth from the host orbit into the implant, which decreases the possibility of implant extrusion or infection and allows enhanced healing of defects in the overlying conjunctiva. Extraocular muscle fixation onto the implant permits motility and assists in the prevention of implant extrusion.
在摘除一匹5岁表演用马的一只眼睛后，植入了羟基磷灰石眼眶植入物。制作了定制的角膜巩膜假体并安装在羟基磷灰石植入物上。植入物和手术耐受性良好。马眼摘除术后需要放置美容假体，以使马能够恢复比赛。虽然报道的并发症包括假体挤出、感染和美容效果不佳，但已使用由甲基丙烯酸甲酯或硅酮制成的合成球体。由海洋珊瑚制成的羟基磷灰石眼眶植入物可使血管和纤维组织从宿主眼眶长入植入物，这降低了植入物挤出或感染的可能性，并有助于结膜上覆盖缺损的愈合。将眼外肌固定在植入物上可实现眼球运动，并有助于防止植入物挤出。
