目的：探索并发性白内障玻璃体混浊时准确测量眼轴的新方法。方法：用A超测量角膜到晶体后囊的距离，利用B超直观性测量晶体后囊到视网膜的距离，两者相加得出眼轴长度用于人工晶体计算，可避免将玻璃体混浊误认为眼后壁。结果：与常规A超测量法相比，术后残余屈光在1D以上的比例减少12%。结论：本测量法设计合理，准确性高，实用性强。

Objective:To explore a new means for axial eye length measurements when vitreous turbidity in intercurrent cataract.Methods：The distance between the cornea and the posterior capsule of lans was measured with A scan,and the distance between the posterior capsule and the retina by B scan using its intuitionistic quality.The eye length can be got by adding the numbers of A and B scan for IOL power calculation to avoid the mistake of vitreous turbidity as the eye backwall.Results:As compared with routine A scan measurement,the residual refraction error more than 1 dioptre after operation was reduced 12%.Conclusions:The new method is reasonable,accurate and practable.
