Abstract：
Background: The Carlevale lens (FIL SSF, Soleko IOL Division, Italy) is a new lens for suture-less scleral fixation. This paper aimed to systematically review articles on this lens, the surgical techniques used for its implantation, complications and outcomes. Methods: This systematic review was performed following the PRISMA guidelines. The search string used was \"Carlevale\" AND \"scleral fixation\" from inception until March 2024. For completeness, either case-control studies, case reports or case series written in English were included. The authors used the Newcastle-Ottawa scale for the case-control studies and the JBI Critical Appraisal Checklist for case reports and case series. Results: Twenty-nine articles were included. Scleral fixation with Carlevale lens can be performed by creating scleral flaps or, alternatively, by using scleral pockets. The two sclerotomies must be diametrically opposed, and are preferably created by 25-gauge trocars. A pars plana vitrectomy should be performed every time, and the design of the lens should be suitable for self-anchoring to the sclera; the most accredited strategy to achieve this is to avoid scleral sutures. There were only a few intraoperative and postoperative complications reported; vitreous hemorrhages were the most frequent intraoperative events, while the most relevant postoperative complications were vitreous hemorrhages, cystoid macular oedema and transient variations in the intraocular pressure. Excellent results have been obtained in terms of BCVA, IOL centration and stability, mean intraocular pressure, postoperative spherical equivalent, separation between anterior and posterior chamber and the distance of the IOL from anterior chamber structures. Conclusions: The foldable hydrophilic design of the Carlevale lens has shown good effectiveness, IOL stability and few intra and post-operative complications.
摘要：
背景：Carlevale镜头（FILSSF，SolekoIOL部,意大利）是一种用于无缝线巩膜固定的新型晶状体。本文旨在系统地回顾关于这种镜头的文章，用于植入的手术技术，并发症和结果。方法：本系统评价是按照PRISMA指南进行的。从开始到2024年3月，使用的搜索字符串为“Carlevale”和“巩膜固定”。为了完整性，无论是病例对照研究，纳入了英文病例报告或病例系列.作者将纽卡斯尔-渥太华量表用于病例对照研究，将JBI关键评估清单用于病例报告和病例系列。结果：共纳入29篇文献。巩膜固定与Carlevale透镜可以通过创建巩膜瓣或，或者，通过使用巩膜袋。两个巩膜切开术必须截然相反，并且优选地由25规格的套管针创建。每次都应该进行平坦部玻璃体切除术，并且晶状体的设计应适合于自锚定到巩膜;实现这一点的最认可的策略是避免巩膜缝合。术中和术后仅有少数并发症报道；玻璃体出血是最常见的术中事件。而最相关的术后并发症是玻璃体出血，囊样黄斑水肿和眼内压的短暂变化。在BCVA方面获得了优异的结果，IOL浓度和稳定性，平均眼内压,术后等效球形，前房和后房之间的分离以及IOL与前房结构的距离。结论：Carlevale透镜的可折叠亲水设计显示出良好的有效性，IOL稳定，术中和术后并发症少。
