METHODS: This study retrospectively analyzed 10 cases(10 eyes)with severe ocular trauma which had accepted FCVB implantation performed in Affiliated Xiaolan People's Hospital, Southern Medical University from January 2018 to July 2020. Ciliary body function was judged by score which was made by preoperative examination results. The case which scored 5 or less was studied as ciliary failure: 8 eyes scored more than 5, 2 eyes scored 5 or less. Followed up for 1-31mo, the postoperative best corrected visual acuity(BCVA)and intraocular pressure, anterior chamber, retinal reattachment, FCVB condition and adverse reactions were observed.

RESULTS: The operations of 9 eyes with aphakia eyes were successful. Iridodialysis occurred during the operation of 1 eye with lens. Retinal reattachment was found in all 10 eyes, and the position of FCVB in all patients was proper. There was no severe adverse reactions. Comparing the preoperative and postoperative BCVA and intraocular pressure, the difference was not statistically significant(P>0.05). In the group(8 eyes)that ciliary body function scored more than 5, 2 eyes had a supplementary operation individually, 1 eye underwent 2 supplementary operations. In the group(2 eyes)which scored 5 or less, supplementary operations were performed 5 times in 1 eye, only 1 time in the other one case.

CONCLUSION: Implantation of FCVB is a safe option to treat severe ocular trauma. But the postoperative visual acuity cannot be improved. The ciliary body function associates with persistent intraocular hypotension and shallow anterior chamber after FCVB implantation.
