【摘要】 本文总结７６例８２眼人工晶体植入术后理论球镜度，分Ａ超精确测量组（Ａ组），普通Ｂ超测量计算组（Ｂ组），直接估算组（Ｃ组），对预设人工晶体屈光度的准确性进行对比分析。结果Ａ组最为准确，但仍偏向轻度远视状态，Ｂ组准确性最差，４６．６７％超出±２．００Ｄ，Ｃ组１７％超出±２．００Ｄ，二者超出率有显著差异（Ｐ＜０．０５）。建议人工晶体Ａ值使用生产厂家提供的参考值，不以普通Ｂ超测量的眼球轴长为预设人工晶体屈光度的依据。更多还原

【Abstract】 The theoretical spherical diopter after IOL implantation in 76 cases (82 eyes) were reported and the accuracy of the implanted IOL diopter among the A ultrasonic wave measured group (group A),the group calculated after general B ultrasonic wave measurement (group B)and the direct estimated group (group C) were analysed.The results demonstrated that group A was the most accurate,but it was partial to the slight hyperopia situation,group B was the worst.46 67% of the eyes in group B and 17% of the eyes in group C exceeded ±2 00D,there were statistically significant differences between them(p<0 05).We suggest that the A constant which was afforded by the factory is used and the length of eye ball axis used to reckon in advance IOL diopter dont be measured by B ultrasonic wave.更多还原
