ABSTRACT
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 ANDCONCLUSION:
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.
