Background: Foldable capsular vitreous body (FCVB) was designed to treat severe retinal detachment. The aim of this study was to evaluate the efficacy and safety of the implantation of foldable capsular vitreous body in 1-year follow-up. Methods: A retrospective analysis was conducted for 20 patients with severe ocular trauma or silicone oil (SO) dependent eyes underwent vitrectomy and FCVB implantation in a 1-year follow-up. All treated eyes were peformed clinical examinations involved the visual acuity (VA) examination, Goldmann applanation tonometer, noncontact specular microscopy, fundus photography, B-Scan examination and optical coherence tomography (OCT). The groups were compared with t-test and the McNemar-Bowker test. Results: In 1-year follow-up, 20 eyes were evaluated in the study. FCVB well supported the vitreous retina in all treated eyes, and 6 treated eyes achieved retinal reattachment 12 months after FCVB implantation. There were no significant differences in VA before and after FCVB implantation (P = 1.000). In addition, the postoperative IOP markedly elevated from the preoperative IOP of 12.90 ± 7.06 mmHg to 15.15 ± 3.36 mmHg (P = 0.000017). The intraocular pressure (IOP) of 10 eyes maintained at a normal level after surgeries. The other 10 eyes showed slightly lower IOP within the acceptable level. Though two patients developed keratopathy and ocular inflammation respectively, other treated eyes were symmetric with fellow eyes showing satisfactory appearance. Moreover, there was no SO emulsification or leakage happened in the observation. Conclusions: FCVB implantation was an effective and safe treatment in the eyes with severe retinal detachment.
Background: To investigate theefficacy and safety of the foldable capsular vitreous body(FCVB) in the treatment of vitreoretinal diseases. Methods: A retrospective analysis was conducted involving 20 patients (20 eyes) who underwent FCVB implantation in our hospital from September 2017 to April 2018. All the patients underwent vitrectomyand FCVB implantation, a standard three-port vitrectomy was performed, and the FCVB was implanted into the vitreous cavity. At 6 months after surgery, the visual acuity chart, Goldmann applanation tonometer, fundus photography, B-ultrasound examination, and optical coherence tomography (OCT) examination were performed on the treated eyes.The patients’ vision, intraocular pressure, retinal reattachment, and FCVB status were observed. Results: Compared with the preoperative measurements, there was no change in visual acuity in 18 eyes at 6 months after FCVB implantation, and the difference was not significant (P=1.000); the intraocular pressure of these 18 eyes returned to normal, and the difference was significant (P=0.00001); in fundus photographyimages of these 18 eyes, B-ultrasound,OCT showed good retinal reattachment, FCVB distributed well in the vitreous cavity and evenly supported the vitreous retina and there was no obvious abnormality. The eyes were symmetrical, and the eyeball activity was normal. One patient developed eyeball atrophy after surgery, and one patient developed ocular inflammation after surgery. The condition improved after treatment. Conclusions: FCVB is an effective and safe vitreous substitute during the 6-month implantation period and is able to maintain eye shape, intraocular pressure and good aesthetics.
As a modification to scleral buckling surgery, we evaluated the efficacy and primary safety of treating rhegmatogenous retinal detachment by using foldable capsular vitreous body scleral buckling in five patients. The observation time after the operation was at least 12 weeks.

Background To evaluate the feasibility of and identify problems in treating complex rhegmatogenous retinal detachment using foldable capsular buckle scleral buckling. Methods This prospective clinical study enrolled five patients with complex rhegmatogenous retinal detachment treated with foldable capsular buckle scleral buckling at the 988th Hospital of People’s Liberation Army Joint Logistic Force, China. During the 24-week follow-up period, the patients underwent measurements of their best-corrected visual acuity, slit-lamp examination, indirect ophthalmoscopy, and visual field testing. Additionally, B-ultrasound and fundus photography of the patients’ retinal reattachments helped evaluate the treatment’s post-surgery efficacy. We determined the safety of foldable capsular buckle scleral buckling based on infection, eye pain, diplopia, elevated intraocular pressure, and other postoperative severe complications. Results All five patients’ complex rhegmatogenous retinal detachments were successfully treated and evaluated via B-ultrasound and fundus photography after surgery. Visual acuity was enhanced in four patients 24 weeks after surgery, while the remaining patients developed diplopia after surgery. No other complications were observed. Conclusion This pilot study preliminarily determined that foldable capsular buckle scleral buckling is feasible for efficient and safe treatment of complex rhegmatogenous retinal detachment. These results support this surgery as a potential and novel alternative to current extraocular procedures for treating complex rhegmatogenous retinal detachment. Trial registration The prospective observational clinical study protocol was approved by the Institutional Review Board and Ethics Committee and registered at the clinical research center in the 988th Hospital of People’s Liberation Army Joint Logistic Force, China (9,882,019,000).
