摘　　要：随着白内障手术相关技术的优化,高端晶状体投入临床应用,白内障手术已处于屈光手术时代,通过手术矫正以恢复患者最佳屈光状态的技术方法备受关注,使得白内障术前的生物学测量及人工晶状体（IOL）屈光度的计算显得至关重要,因此临床医师应充分了解相关的测量机制及可控制误差的来源,尽可能减小术后屈光误差,提高术眼的视觉质量.白内障术前的生物学测量涉及不同方法,如眼轴长度、角膜曲率和前房深度的测量,而IOL的计算方法包括标准屈光度法、传统理论或经验公式法及光线追踪算法等.临床医师只有将白内障术前生物学测量与IOL屈光度计算方法进行适宜联合,才能确保术眼获得满意的视觉质量.As the development of surgery related technology and clinical application of premium intraocular lens （IOL）,cataract surgery has been in the era of refractive surgery.To restore the refractive system by surgery has been focused on and challenges have been brought up in preoperative measurement and accurate IOL power calculation methods.It is necessary to know developments of the related measurement technologies and the possible error resources to decrease refractive errors.Different means of measuring axial length,cornea curvature and anterior chamber depth were related here,co-operated with varied IOL power calculation methods,such as standard power,traditional formulas and real ray tracing method.Researchers should pay close attention to the preoperative measurement and IOL power calculation methods in cataract patients,the combination of accurate measurement with different calculation methods can help to acquire an increasingly satisfactory visual result.
