AIM: To discuss the surgical method of foldable capsular vitreous body(FCVB)implantation and evaluate its therapeutic effect.

METHODS: We retrospectively analysis of 73 cases with severe ocular rupture injury after FCVB implanted and silicone oil dependence after vitrectomy in our Hospital from April 2018 to March 2020. The visual acuity, corneal, anterior chamber depth, intraocular pressure, retina, FCVB status, their satisfaction with appearance is observed after treated from 1-20mo.

RESULTS: All the 73 patients in this group were successfully operated. The amount of silicone oil injected into the FCVB during the operation was 2.4-4.2mL, with an average of 3.5±0.36mL. There were 22 eyes with light perception, 46 eyes with manual perception and 5 cases with immediate index; 19 eyes during postoperative follow-up. Corneal clarity or basic clarity was observed in 19 eyes, corneal local opacity in 31 eyes, and corneal grayish white opacity in 23 eyes. There were 32 eyes with normal anterior chamber, 23 eyes with shallow anterior chamber, and 18 eyes with completely disappeared anterior chamber. The intraocular pressure(IOP)could not be tested in 22 eyes due to cornea, 17 eyes with IOP less than 8mmHg, and 34 eyes with IOP between 8 and 21mmHg. Slit-lamp microscope examination showed no obvious deviation of the position of FCVB. The postoperative appearances were satisfactory and basically satisfactory in 52 eyes(71%). No balloon rejection, sympathetic ophthalmitis or other obvious surgical complications were observed in all cases.

CONCLUSION: For the patients with severe eyeball rupture and silicone-oil-dependent eyes, the FCVB implantation can prevent from eyeball extraction. The operation is safe and effective, and the eyeball shape and intraocular pressure can be well maintained.
