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 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.
