摘　　要：人工晶状体(intraocular lens,IOL)在眼内位置的变化将会对屈光状态及眼内像差尤其是高阶像差及成像质量产生影响。IOL在眼内的稳定性主要包括纵向(轴向)位置的稳定及水平位置的稳定,包括IOL有效位置、偏心和倾斜以及旋转稳定性等。囊袋与撕囊口性状、IOL的襻型设计及材质、眼内组织结构及手术操作等多种因素均会影响IOL眼内稳定性,需在白内障手术全流程予以关注。With the advent of the era of precise refractive cataract surgery,intraocular lens(IOL)has been widely used in clinical treatment.The stability of IOL mainly includes the stability of longitudinal position and horizontal position,including the effective position,decentration,tilt,and the rotation stability of IOL.The change of intraocular position of IOL will affect the refractive state and wavefront aberrations,especially the high-order aberrations and imaging quality.We will review the influencing factors of IOL stability,including the characteristics and shapes of capsulorrhexis,the designs and materials of IOL,the eye tissue and the surgery factors,which should be paid more attention.
