AIM:To evaluate the clinical application of hydroxyapatite (HA) orbital implant for plastic surgery of eye. METHODS:Totally 52 cases (52 eyes) underwent three kinds of HA orbital implant procedures. 24 cases (24 eyes) in group A were implanted HA enwrapped self-sclera shell at the first stage. 16 cases (16 eyes) in group B were implanted HA covered double-deck sclera cap at the first stage. 12 cases (12 eyes) in group C were implanted HA enwrapped other-sclera shell at the second stage. RESULTS:Follow-up periods ranged from 3 months to 24 months. After artificial eye slice fixed, most cases got plump eyeball and obtained certain eyeball activity (excellent: 71.2%; good:19.2 %; poor:9.6 %). CONCLUSION:HA orbital implant is the most perfect at the present time.
