聚散度公式可能为无晶状体眼的屈光状态提供一种简单且可靠的计算方法。测量小儿无晶状体眼的屈光误差是困难的。本研究探讨了聚散度公式用于估算此类眼睛屈光状态的准确性和适用性。
对2016年1月至2018年12月期间创建的小儿无晶状体患者的病历进行了回顾性研究。使用基于眼轴长度的聚散度公式来计算无晶状体眼的屈光状态。比较了通过检影验光、自动验光仪以及聚散度公式所确定的屈光值。
共分析了72只眼（47名患者）。通过检影验光（13.01±3.27D）、自动验光（12.90±3.23D）以及聚散度公式（12.70±3.4D）确定了眼睛屈光误差的球镜等效值（平均值±标准差）。检影验光值与聚散度公式、自动验光与聚散度公式以及检影验光与自动验光之间的相关系数分别为0.968、0.987和0.979。Bland - Altman一致性分析显示，检影验光与自动验光、检影验光与聚散度公式以及自动验光与聚散度公式之间球镜等效值的平均差异分别为0.11D、0.31D和0.21D，95%一致性界限分别为 - 1.20至1.41D、 - 1.37至2.00D以及 - 0.90至1.31D。
聚散度公式对于评估小儿患者无晶状体眼的屈光状态是有效的。
A vergence formula may provide a simple and reliable calculation of the refractive status of aphakic eyes. Measuring the refractive error of pediatric eyes with aphakia is difficult. This study investigated the accuracy and applicability of a vergence formula for estimating the refractive status of such eyes. A retrospective review of the medical records, created between January 2016 and December 2018, of pediatric patients with aphakia was conducted. A vergence formula, based on axial length, was used to calculate the refractive status of the aphakic eyes. The refractive values determined using retinoscopy, an automatic refractometer, and the vergence formula were compared. A total of 72 eyes (47 patients) were analyzed. The spherical equivalents of the refractive errors (mean ± standard deviation) of the eyes were determined using retinoscopy (13.01 ± 3.27 D), automatic refractometry (12.90 ± 3.23 D), and the vergence formula (12.70 ± 3.4 D). The correlation coefficient between retinoscopy values determined using retinoscopy and the vergence formula, automatic refractometry and the vergence formula, and retinoscopy and automatic refractometry were 0.968, 0.987, and 0.979, respectively. The Bland-Altman consistency analysis revealed that the mean differences in the spherical equivalent values between retinoscopy and automatic refractometry, retinoscopy and the vergence formula, and automatic refractometry and the vergence formula were 0.11 D, 0.31 D, and 0.21 D, respectively, with 95% limits of agreement of−1.20 to 1.41 D,−1.37 to 2.00 D, and−0.90 to 1.31 D, respectively. The vergence formula was effective for evaluating the refractive status of aphakic eyes in pediatric patients.
