本文通过 134例后房型人工晶体植入眼 ,分不同眼轴长度 ,比较了 SRK- 公式与第三代理论公式预测人工晶体屈光度的准确性。对短轴眼 (L≤ 2 2 mm)和中轴眼 (2 2 m2 4.5 mm) ,SRK- 公式则出现了较为明显的误差 :SRK- 公式有 15 %的误差超出 2 D,而 Holladay公式仅有 2 % ,Hoffer- Q和 SRK/ T则无大于 2 D的误差。各第三代理论公式对轻度长轴眼 (2 4.5 2 8.4mm) ,无论从统计学上 (P<0 .0 5 )或临床上均比 SRK- 公式准确。故认为第三代理论公式比SRK- 公式更适合于中国人眼 ,建议有条件的眼科医师选择第三代人工晶体计算公式 ,以提高预测人工晶体屈光度的准确性
In this paper, 134 cases of posterior chamber intraocular lens implantation, sub-axial length of different sub-SRK- and third-generation theoretical formula to predict the accuracy of intraocular lens diopter. For the short-axis (L≤2 2 mm) and axial (2 2 m 4.5 mm), SRK- The formula shows obvious errors: SRK-formula has 15% error exceeding 2 D, while Holladay formula only has 2%, Hoffer-Q and SRK / T have no error greater than 2-D. The third-generation theoretical formulas are only clinically superior to SRK-formulas in predicting mild long axis (2 4.5 2 8.4 mm), both were statistically (P <0.05) or clinically more accurate than the SRK-formula. Therefore, the third-generation theoretical formula is more suitable than the SRK-formula for the Chinese human eye, it is recommended that qualified ophthalmologists choose the third-generation intraocular lens formula to improve the accuracy of predicting intraocular lens refraction
