摘　　要：目的:比较IOL Master 700与Lenstar LS900对高度近视合并白内障患者术前眼生物测量的差异性、相关性、一致性及人工晶状体(IOL)度数计算的准确性。方法:回顾性研究。收集2021-03/2023-03于陆军特色医学中心眼科行白内障超声乳化联合IOL植入手术的高度近视合并白内障患者136例136眼,平均年龄57.38±8.08岁。根据眼轴长度(AL)将患者分为3组:A组(26 mm≤AL≤28 mm)41眼,B组(28 mm30 mm)52眼。术前分别使用两种仪器测量AL、平均角膜曲率(Km)、前房深度(ACD)、晶状体厚度(LT)和白到白距离(WTW)。所有患者均采用Barrett UniversalⅡ公式计算IOL度数,个性化选择适宜的预留屈光度,比较两种仪器的预测屈光误差(PE)和绝对屈光误差(AE)。结果:三组患者中Lenstar LS900测量的AL和ACD均大于IOL Master 700测量值(均P<0.05),且两种仪器测量AL的平均差值C组>B组>A组。两种仪器测量LT、Km与WTW值均无差异(均P>0.05)。两种仪器所得各组生物参数均具有正相关性(均r>0.9,P<0.05)且一致性较好(95%LoA范围较窄)。两种仪器计算的AE无差异(P>0.05),但IOL Master 700计算的PE小于Lenstar LS900(P<0.05),且前者远视偏移百分比更低。结论:在高度近视合并白内障患者中,Lenstar LS900测量AL值大于IOL Master 700,且该差异随着AL的增加而增大,两种仪器对IOL的计算均具有良好的预测性,但IOL Master 700术后屈光误差更小,远视偏移百分比更低。AIM:To compare the differences,correlations and consistency of IOL Master 700 or Lenstar LS900 in preoperative ocular biometry and the accuracy of intraocular lens(IOL)degree calculation of cataract patients with high myopia.METHODS:Retrospective study.A total of 136 cases(136 eyes)of high myopia and cataract patients who underwent phacoemulsification at the ophthalmology department of Army Medical Center of PLA from March 2021 to March 2023 were collected,with a mean age of 57.38±8.08 years.Patients were divided into 3 groups based on axial length(AL):41 eyes in group A(26 mm≤AL≤28 mm),43 eyes in group B(28 mm<AL≤30 mm)and 52 eyes in group C(AL>30 mm).AL,mean keratometry(Km),anterior chamber depth(ACD),lens thickness(LT)and white-to-white(WTW)were preoperatively measured by two instruments,respectively.Barrett Universal II formula was used to calculate the IOL degrees of all patients,the appropriate reserved diopter was decided individually,and the prediction error(PE)and absolute error(AE)of the two instruments were compared.RESULTS:The AL and ACD of patients in the three groups measured by Lenstar LS900 were higher than the AL measurd by IOL Master 700(all P<0.05),with a difference of AL measured by the two devices:group C>group B>group A.However,there was no statistical significance in LT,Km,and WTW measured by the two instruments(all P>0.05).All biometric parameters measured by the two devices were positively correlated(all r>0.9,P<0.05),and consistent(95%LoA of all groups were narrow).There was no statistically significant difference in AE calculated by the two devices(P>0.05),but the IOL Master 700 calculated a smaller PE than Lenstar LS900(P<0.05),with lower percentage of hyperopic shift in IOL Master 700.CONCLUSION:In cataract patients with high myopia,AL measured by Lenstar LS900 is longer than that by IOL Master 700,and the differences of AL increase along with the growth of AL.Both devices have a good prediction for IOL calculation,but IOL Master 700 has less refractive error,lower percentage o
