Scleral-fixated intraocular lens implants-evolution of surgical techniques and future developments

Eye (Lond). 2021 Nov;35(11):2930-2961. doi: 10.1038/s41433-021-01571-5. Epub 2021 Jun 11.

Abstract

Varied options are available for the implantation of secondary intraocular lens implants in the absence of zonular or capsular support. Loss of the capsule can occur in the context of complicated cataract surgery, trauma or inherited conditions such as Marfan syndrome or pseudoexfoliation. Approaches to overcome this include optical measures such as the use of spectacles or contact lenses, and surgical therapy incorporating the use of anterior chamber, iris-fixated or scleral-fixated lenses. Surgical techniques to implant scleral-fixated lenses have undergone various modifications, since the first publication of sutured intrascleral fixation described in the 1980s. However, despite the advances in surgical techniques, studies are limited either by their retrospective nature, small sample size and most importantly small duration of follow-up. This comprehensive review aims to amalgamate the evolution of various surgical techniques with regards to intrascleral lens fixation and suggests areas for future development.

摘要: 经巩膜缝线固定的眼内人工晶状体植入术——手术技术的演变与未来发展摘要在缺乏晶状体悬韧带或囊膜支撑的情况下, 二期人工晶状体植入有多种选择。在复杂性白内障手术、外伤或遗传性疾病 (如马凡氏综合征或假性脱落) 的白内障手术中, 可能会出现晶状体囊膜缺失的情况。而光学治疗措施 (佩戴框架眼镜或隐形眼镜) 以及手术方法 (结合使用前房、虹膜固定或巩膜固定的人工晶状体) 可以解决问题。自20世纪80年代首次发表关于巩膜内固定术的文章以来, 植入经巩膜缝线固定人工晶体的外科技术经历了各种各样的改进。然而, 尽管外科手术技术有了进步, 但由于研究为回顾性、样本量小和最重要的随访时间短, 研究结果不尽人意。本综述旨在深度探讨经巩膜缝线固定人工晶状体植入术的进展, 并对今后的发展方向提出建议。经巩膜缝线固定的眼内人工晶状体植入术——手术技术的演变与未来发展摘要在缺乏晶状体悬韧带或囊膜支撑的情况下,二期人工晶状体植入有多种选择。在复杂性白内障手术、外伤或遗传性疾病(如马凡氏综合征或假性脱落)的白内障手术中,可能会出现晶状体囊膜缺失的情况。而光学治疗措施(佩戴框架眼镜或隐形眼镜)以及手术方法(结合使用前房、虹膜固定或巩膜固定的人工晶状体)可以解决问题。自20世纪80年代首次发表关于巩膜内固定术的文章以来,植入经巩膜缝线固定人工晶体的外科技术经历了各种各样的改进。然而,尽管外科手术技术有了进步,但由于研究为回顾性、样本量小和最重要的随访时间短,研究结果不尽人意。本综述旨在深度探讨经巩膜缝线固定人工晶状体植入术的进展,并对今后的发展方向提出建议&#12290.
