摘要白内障手术后人工晶状体(intraocular lens，IOL)的位置并非固定不变，大多会发生线性运动，随后相对稳定。术后IOL轴向位置的变化受到许多因素的影响，包括眼球解剖结构、手术方式、IOL的设计、晶状体囊袋等。其中，IOL襻作为IOL的支撑元件，其设计对IOL轴向位置的稳定性起着关键作用，襻的材质、襻的厚度与宽度、光学部与襻的关系、襻的数量、襻型、襻夹角以及襻径等均是影响术后IOL轴向位置的因素。 (国际眼科纵览，2024, 48：261－266)

abstractsThe position of the intraocular lens(IOL) after cataract surgery is not fixed, and most of it will undergo linear motion after surgery, and then it is relatively stable. The axial position of the IOL is affected by many factors, including the anatomical structure of the eyeball, the surgical method, the design of the IOL, the lens capsular bag, etc. As the supporting element of the IOL, the design of the IOL loop plays a key role in the stability of the axial position of the IOL, including the material of the loop, the thickness and width of the loop, the relationship between the optical part and the loop, the number of loops, the type of loop, the angle of the loop and the diameter of the loop.
