摘　　要：超声乳化白内障手术技巧和人工晶状体（intraocular lens，IOL）制作工艺日趋完美，白内障患者视力得到提高，但部分患者术后仍残留屈光不正而影响视觉质量。如何提高白内障术后患者裸眼视力成为近年的研究热点。将物理光学、激光技术、电子信息工程与液晶显示等技术结合到IOL制作工艺中，实现植入眼内的IOL屈光力的调整，以矫正原有IOL在屈光力方面所出现的偏差，称为可调屈光力的IOL。根据调节是否需要手术介入分为有创型和无创型两类。有创型又包括多元可调屈光力IOL、器械可调屈光力IOL和重复可调屈光力IOL等；无创型又包括光可调屈光力IOL、磁可调屈光力IOL、液晶变焦可调屈光力IOL和通过飞秒激光或双光子化学技术调整IOL屈光力等。可调屈光力的IOL是制作工艺与边缘学科的巧妙结合，促进眼科新技术的发展。虽然目前部分IOL仍处于试验阶段，但为白内障术后患者获得良好的裸眼视力和生存质量带来了更好的前景。Patients required the improving vision after phacoemulsification. However, a lot of pa- tients need spectacles to improve uncorrected distance visual acuity after the surgery. Researchers focused on the methods to correct the refractive error after the cataract surgery. The power adjustable intraocular lens （IOL） technologies are available or under development. This includes IOL technologies that can adjust the IOL power using secondary surgical procedures, such as muhicomponent IOL, the mechanically adjustable IOL, and the repeatedly adjustable IOL; IOLs that can be adjusted noninvasively in the postoperative set- ting, such as light adjustable IOL, the magnetically adjustable IOL, the liquid crystal IOL with wireless con- trol, and IOL that can be adjusted using the femtosecond laser or 2-photon chemistry. Adjustable IOL power technology plays an important role in the IOL development, although some lens are in the pilot phase. Pa- tients will acquire perfect vision and life qualification in future.
