摘　　要：目的对比分析不同仪器测量角膜曲率计算人工晶体屈光度。方法回顾分析方便选取的该院2016年1月—2017年1月期间180例患者临床资料,行白内障超声乳化摘除及人工晶体植入术,分别采用人工角膜曲率计、自动角膜曲率计和角膜地形图仪测量角膜曲率,计算人工晶体屈光度,然后将数据进行综合对比和分析。结果通过相关数据进行比较发现3种不同仪器测得角膜曲率最大值(43.87±1.65)、(44.21±1.81)、(44.32±1.62)、最小值(42.89±1.56)、(43.30±1.78)、(43.40±1.65)、平均曲率(43.42±1.64)、(43.65±1.67)、(43.81±1.63)对比,差异无统计学意义(P>0.05);3种不同方法计算人工晶体屈光度,眼轴≤25 cm分别为(19.19±2.49)、(18.74±2.50)、(18.87±2.50),眼轴≥25 cm分别为(42.89±1.56)、(43.30±1.78)、(43.40±1.65)对比,差异无统计学意义(P>0.05)。结论人工角膜曲率计、自动角膜曲率计和角膜地形图仪测量角膜曲率值,均可计算人工晶体屈光度,并且相关数据真实可靠、准确。但角膜过平、过陡者,建议使用角膜地形图仪。Objective To compare and analyze the different instruments measurement of corneal curvature in calculating the intraocular lens diopter. Methods 180 cases of patients in our hospital from January 2016 to January 2017 were convenient selected and respectively were treated with cataract ultrasound emulsification excision and intraocular lens implantation, and the corneal curvature was measured by the artificial corneal curvature, automatic corneal curvature and corneal topography and the intraocular lens diopter was calculated and then the data were comprehensively analyzed and compared. Results The relevant data showed that the maximum, minimum and mean curvature of three different instruments were respectively（43.87±1.65）,（44.21±1.81）,（44.32±1.62） and（42.89±1.56）,（43.30±1.78）,（43.40±1.65）and（43.42±1.64）,（43.65±1.67）,（43.81±1.63）, and the differences were not statistically significant（P〈0.05）, and the intraocular lens diopter and axis oculi25 cm calculated by three different methods and were respectively（19.19±2.49）,（18.74±2.50）,（18.87±2.50） and（42.89±1.56）,（43.30±1.78）,（43.40±1.65）, and the differences were not statistically significant（P〈0.05）. Conclusion The artificial corneal curvature, automatic corneal curvature and corneal topography measurement of corneal curvature can calculate the intraocular lens diopter and the relevant data are reliable and accurate, but for the patients whose cornea is too flat and steep, it is suggested to use the corneal topography.
