摘要
目的全面客观地评价IOL Master计算人工晶状体屈光度的精确度。方法121例(154眼)老年性白内障,术前分别应用IOL Master和眼科传统设备两种方法测量眼部参数并计算所需人工晶状体的屈光度,术后检查术眼屈光误差。结果眼轴长度方面:短眼轴和正常眼轴组中两种设备测得的值差异有统计学意义(P<0.001);前房深度方面:正常眼轴和长眼轴组中两种设备测得的值差异有统汁学意义(P=0.001);屈光误差方面:IOL Master法在各公式中的误差均小于传统的A超法。误差≤1D的比例高于传统的A超法。结论IOL Master测量并计算人工晶状体屈光度的精确度高于传统的方法。
Objective To assess the precision of IOL Master in calculating intra-ocular lens power. Methods IOL Master and ultrasound biometry were performed in 154 eyes to measure AL and ACD. SRK II,Haigis ,Holladay,Hoffer Q and SRK-T formulas were used for IOLs power calculation. 3 months after surgery, patients were checked their refractive error. Patients were divided into three groups in AL assesed by IOL Master：short group（ 〈22 ram） ,nor- mal group （22-26 mm） and long group（ 〉 26 mm）. Results A- bout axial length, there was a statistically significant difference in short and normal groups （ P 〈 0. 001 ） between the two measure- ments. About anterior chamber depth, there was a statistically signif- icant difference in eyes with normal or long length （ P = 0. 001 ）. A- bout postoperative mean absolute refractive error, IOL Master pro- duced smaller readings in general. And in all cases IOL Master pro- duced higher percentages of ≤ 1.00D. Conclusions IOL Master provided a more significant precision than ultrasound biometry.
