摘　　要：背景:人工晶体在白内障术眼囊袋内可以前移,但目前还不能够对该动态调节过程中人眼屈光变化进行监测,临床数据的难以获得使人工晶体前移与引起的人眼屈光调节量之间的关系目前还未明确。目的:观察人工晶体眼内移动对人眼屈光调节力的影响。方法:基于Hwey-LanLiou眼模型,采用ZEMAX光学设计软件实现光线追迹的方法研究了人工晶体在眼内的前移与人眼屈光调节量的关系。结果与结论:人工晶体每前移一定的距离,人眼所获得的屈光调节量不恒定;调节量大小依赖于眼轴长度和所需植入的人工晶体,特别是眼轴长度;对于不同眼轴长度术眼中的人工晶体前移,人眼所获得的屈光调节量与眼轴长度呈负相关。BACKGROUND：The intraocular lens can move forward during cataract optic capsular surgery,but the changes in the human eye diopter cannot be monitored in such a dynamically adjustment process,it is difficult to obtain clinical data which could reveal the correlation between intraocular lens forward and human eye diopter adjustment.OBJECTIVE：To observe the influence of intraocular lens movement on the adjustment of human eye diopter.METHODS：Based on Hwey-Lan Liou eye model,using optical design software ZEMAX to realize ray tracing,the relationship of intraocular lens forward in the eye with the adjustment of human eye diopter was investigated.RESULTS AND CONCLUSION：Once the intraocular lens forward for a certain distance,human eye obtained the amount of accommodating diopter was not constant;the adjustment amount depended on the axial length and the required intraocular lens implantation,especially in axial length;for the intraocular lens forward of the surgical eyes at different axial lengths,the amount of accommodating human eye diopter was negatively correlated with axial length.
