目的评价新一代人工晶状体度数计算公式（EVO 2.0和Kane）与现有公式（Barrett Universal II、Haigis和SRK/T）在儿童白内障患者中的准确性。方法回顾性研究。我们在温州医科大学眼科医院入组110只眼（110例患者）。所有患者均顺利接受白内障手术并在囊内植入后房型人工晶状体。我们计算1个月的平均预测误差（PE）和1屈光度内的百分比(D)来评估准确性，并将百分比> 2D定义为预测事故。然后，我们根据年龄和轴长（AL）进行亚组分析。结果平均年龄37.45 +/- 23.28个月，AL 21.16 +/- 1.29 mm。所有患者的平均PE为Barrett（- 0.30）、EVO（0.18）、Haigis（- 0.74）、Kane（- 0.36）、SRK/T (0.58), p < 0.001。此外，对于年龄小于24个月、AL为21 mm的患者，EVO和SRK/T公式相对准确（bbb51 /69和43/58，以及< 3/69和3/58）。结论对于年龄大于24个月且AL > ~ 21 mm的患者，Barrett、EVO和Kane公式相对准确，而对于年龄小于24个月且AL的患者，Barrett、EVO和Kane公式相对准确
Purpose To evaluate the accuracy of newer generation intraocular lens (IOL) power calculation formulas (EVO 2.0 and Kane) with established formulas (Barrett Universal II, Haigis and SRK/T) in pediatric cataract patients.Methods Retrospective study. We enrolled 110 eyes (110 patients) in Eye Hospital of Wenzhou Medical University. All patients underwent uneventful cataract surgery and implanted with posterior chamber IOL in the bag. We calculate the mean prediction errors (PE) and percentage within 1 diopter (D) at 1 month to assess the accuracy, and percentage > 2D was defined as prediction accident. Then, we performed subgroup analysis according to age and axial length (AL).Results The mean age and AL were 37.45 +/- 23.28 months and 21.16 +/- 1.29 mm. The mean PE for all patients was as follows: Barrett (- 0.30), EVO (0.18), Haigis (- 0.74), Kane (- 0.36), and SRK/T (0.58), p < 0.001. In addition, EVO and SRK/T formulas were relatively accurate in patients younger than 24 months and with AL 21 mm (both > 51/69 and 43/58, and < 3/69 and 3/58).Conclusions In patients older than 24 months and with AL > 21 mm, Barrett, EVO, and Kane formulas were relatively accurate, while in patients younger than 24 months and with AL
