AIM: To investigate the clinical effect of preserved amniotic membrane transplantation in the treatment to conjunctival rupture, dehiscence and socket contracture after hydroxyapatite(HA)orbital implantation.

METHODS: In 16 cases of conjunctival rupture and socket contracture after HA orbital implantation, conjunctival tension was release by operation and preserved amniotic membrane was transplanted on conjunctival scleral exposure area.

RESULTS: In all cases, conjunctiva healing, completely cover the sclera and conjunctiva socket recover ideal depth after operation in 15 cases, 1 case was fail.

CONCLUSION: Preserved amniotic membrane transplantation is an effective method to treat conjunctival dehiscence and keeping the ideal conjunctival socket depth after orbital implantation.
