Current intraocular lens (IOL) explantation techniques are limited to cutting the optic and removing the pieces through a small incision or folding single-piece acrylic IOLs using a 2-handed technique. Poor execution of IOL explantation can result in injury to intraocular structures, including the corneal endothelium and iris. The minimally invasive cartridge pull-through technique uses a cartridge for IOL implantation and new forceps optimized for secure grasping of the IOL for removal. This method involved less manipulation in the anterior chamber, thereby reducing the risks for complications such as corneal and iris injuries. A dropped IOL lying on the retinal surface can be extracted directly without lifting it onto the iris first. The cartridge pull-through technique offers a more streamlined and potentially safer approach for IOL explantation.
目前的人工晶状体（IOL）摘除技术仅限于通过小切口切割光学部并取出晶状体碎片，或使用双手技术折叠式丙烯酸单片 IOL。如果 IOL 摘除技术执行不当，可能会导致眼内结构（包括角膜内皮和虹膜）损伤。微创卡式套索拉除法使用用于 IOL 植入的卡式套索和经过优化的新夹具，以安全地抓住 IOL 进行移除。这种方法在前房内的操作较少，从而降低了角膜和虹膜损伤等并发症的风险。落在视网膜表面的掉落 IOL 可以直接提取，而无需先将其提升到虹膜上。卡式套索拉除法为 IOL 摘除提供了一种更流畅、潜在更安全的方法。
