玻璃体替代物是玻璃体切割术后的必需品，用于填充玻璃体腔，恢复玻璃体的支撑视网膜、屈光和细胞屏障等功能。严重眼外伤及复杂视网膜脱离引起的视网膜/脉络膜脱离，如选用传统的玻璃体替代物(如硅油)填充，部分患者会出现硅油依赖眼或眼球萎缩，眼球难以保全。折叠式人工玻璃体球囊(foldable capsular vitreous body,FCVB)是我国独立研发的挽救眼球的人工玻璃体，属于国际首创，可以精细模拟自然玻璃体的结构，恢复玻璃体的部分功能。目前临床研究证实FCVB不仅可以有效避免硅油的并发症，还可以维持后房空间，缓慢恢复睫状体的功能，从而治疗硅油依赖眼，阻止眼球进一步萎缩。该文综述了FCVB的研究背景、结构特点、临床应用和拓展研究进展。
Vitreous substitutes are necessary after vitrectomy to fill the vitreous cavity and restore the vitreous to support retinal, refractive, and cellular barrier functions. Severe ocular trauma-induced retinal/choroidal detachment filled with traditional vitreous substitutes (e.g., silicone oil) can lead to silicone oil-dependent eyes and ocular atrophy in some patients, making it difficult to preserve the eye. Foldable capsular vitreous body (FCVB) is an artificial vitreous body independently developed in China to save the eye, which is the first of its kind in the world and can finely simulate the structure of natural vitreous body and restore some of the functions of vitreous body. It has been clinically proven that it can not only effectively avoid the complications of silicone oil, but also maintain the posterior chamber space and slowly restore the function of the ciliary body, thus treating silicone oil-dependent eyes and preventing further atrophy of the eye. This article reviews the research background, structural features, clinical applications and extended studies of FCVB.
目的：探讨折叠式人工玻璃体球囊(foldable capsular vitreous body，FCVB)植入术的护理配合。方法：对2018年6月至12月接受FCVB植入术的33例患者的术中护理配合进行回顾性分析和总结。结果：33例患者的手术均能顺利进行，术后裂隙灯显微镜检查示折叠式人工玻璃体球囊位置均居中；患者均未见球囊排斥、交感性眼炎及其他明显手术并发症。结论：FCVB是全球首创的革命性产品，手术前充分的术前准备，系统规范化的手术巡回配合，是保证手术顺利完成的关键。
Objective: To explore the nursing cooperation of foldable capsular vitreous body implantation. Methods: The intraoperative nursing cooperation of 33 patients who received the operation from June to December 2018 was retrospectively analyzed and summarized. Results: All the 33 patients underwent successfully, and silt lamp microscopy showed that the position of foldable capsular vitreous body was in the center. No foldable capsular vitreous body rejections, sympathetic ophthalmitis or other obvious surgical complications were observed in all cases. Conclusion: Foldable capsular vitreous body is a global innovative product. Adequate preoperative preparation before surgery and systematic and standardized surgical tour coordination are the keys to thesuccessful completion of surgery.
