摘　　要：目的探讨提高预设人工晶体屈光度准确性的方法。方法对86例超声乳化联合IOL植入术前的年龄相关性白内障患者,应用IOLmaster测量眼轴长度和角膜曲率使用SRKII或SRK/T公式计算植入IOL度数术后3月检查患者屈光状态。结果术前计算IOL屈光度平均为17.90±3.45D,预设IOL屈光状态:18.31±3.50D,术后屈光状态:正视者78例(90.69%),轻度近视6例(6.97%),轻度远视2例(2.30%)结论应用IOLmaster测量IOL度数,具有准确性,非接触性,操作简便,安全而且病人易于接受的特点,但也有一定局限性,不能完全替代A超。Objective To study the accuracy of predicating intraocular lens powers by employing IOLMaster biometry data. Methods IOLMaster data was employed for the prediction of implanted intraocular lenses in 86 cases with age-related cataract. Three months after cataract surgery, the actual postoperative refraction was measured. Results The preoperative prediction of IOLs in 86 cases was 17.90±3.45D, the intended refraction was 18.31±3.50D. The actual postoperative refraction： 78 cases（90.69%）in emmetrope, 6 cases（6.97%）in slight myopia, 2 cases（2.30%） in slight hyperopia. Conclusion IOLMaster biometry in predicting IOL power is a precise, effective and noncontact method and can be wildly used in some certain conditions.
