摘　　要：目的比较IOLMaster与ALLEGRO Oculyzer测量前房深度的差异，并对两者的一致性进行评价。方法前瞻性研究。对第三军医大学大坪医院眼科拟行白内障手术的患者53例（87眼），分别用IOL Master和ALLEGRO Oculyzer进行前房深度测量。采用配对t检验比较两者结果的差异．采用Pearson相关分析与Bland—Ahman分析评价两者的一致性。结果IOLMaster与ALLEGRO Oculyzer测量的前房深度值分别为（3．17±0．44）mm和（3．21±0．46）mm，差异有统计学意义（t=3．26，P〈0．05）。两种方法所得测量值有高度相关性（r=0．96，P〈0．01）；Bland—Ahman分析95％一致性界限为-0．20～0．28mm，两者有较好的一致性。结论IOL Master与ALLEGRO Oculyzer测量的前房深度值可以在人工晶状体的计算中交互使用。Objective To compare the difference and assess the consistency between IOL Master and ALLEGRO Oculyzer for measuring anterior chamber depth （ACD）. Methods It was a prospective study. Fifty-three patients （87 eyes） were recruited and ACD was measured by IOL Master and ALLEGRO Oeulyzer. The statistical significance of the difference between the measurements was evaluated by a paired t test and consistency was assessed by Pearson＇s correlation and Bland-Ahman analysis. Results The mean ACD was 3.17±0.44 mm and 3.21±0.46 mm with IOL Master and ALLEGRO Oeulyzer, respectively. The difference between the two measurements was statistically significant （t=3.26, P〈0.01） and a high correlation was found between the two measurements （r=0.96, P〈0.01）. Bland-Altmann analysis showed that the two measurements had comparable results for ACD with 95% limits of consistency, -0.20 to 0.28 ram. Conclusion IOL Master and ALLEGRO Oeulyzer can be used interchangeably for ACD measurement to calculate intraocular lens power.
