巩膜内无缝线后房型人工晶状体固定

巩膜内无缝线后房型人工晶状体(intraocular lens,IOL)固定是近年来发展的一种矫正无囊膜支持无晶状体眼的新方法,可有效避免缝合IOL与缝线相关的并发症。巩膜内无缝线后房型IOL固定有多种方法,包括制备巩膜隧道类的采用针或玻璃体视网膜刀进行的无缝线巩膜内固定IOL植入、Yamane法带凸缘巩膜内IOL双针固定技术、经结膜入路法、自闭式巩膜切口固定法;以及制备巩膜瓣类的纤维蛋白胶辅助的巩膜内无缝线IOL固定术、无纤维蛋白胶辅助需缝合的IOL固定术。结果显示巩膜内无缝线后房型IOL固定是一种有效、安全、实用的手术方法,术后短期随访效果令人满意。但迄今为止,文献报道的病例数有限且随访时间较短,尚需对更多病例进行长期随访以明确其远期效果及安全性、稳定性。

Sutureless intrascleral intraocularlens fixation

Sutureless intrascleral  intraocular lens（IOL） fixation methods are newer and have been developed to eliminate the suture-related complications of sutured scleral fixation methods.The methods of sutureless intrascleral fixated  including preparing scleral tunnels such as sutureless sclera internal IOL fixation with needle or vitreous retinal knife for sclera tunnel preparation, Yamane method for flanged intrascleral IOL fixation with double-needle technique, transconjunctival intrascleral IOL fixation, and self-sealing sclera incision fixation, as well as the method of preparing scleral flap such as fibrin glue-assisted intrascleral IOL fixation and sutureless glueless intrascleral IOL fixation. The results showed that sutureless intrascleral IOL fixation was an effective, safe and practical operation method. While the reports in the literature include a limited number of cases and the follow-up periods are short. Short-term results of these new methods are acceptable. However, studies including more cases with longer follow-up are needed in the future. (Int Rev Ophthalmol, 2020, 44：91-99)
