OBJECTIVE
To determine the relationship between the preoperative axial length and the myopic shift over 3 years after congenital cataract surgery with primary intraocular lens implantation and other related factors.
METHODS
In this retrospective cohort study, the axial length was measured and assigned into 2 groups (>21.5 mm and ≤21.5 mm), visual axis obscuration, laterality of cataract, age of surgery and follow-up time were assessed and compared to the myopic shift.
RESULTS
The mean myopic shift was 3.6 (standard deviation [SD]: 2.3) diopters (D) in all patients; 3.2 (3.3) and 3.9 (3.2) D for each group respectively (=0.359). In unilateral cataracts the mean myopic shift was 6.3 D and in bilateral cases was 3.0 D (=0.001). In bilateral cataracts, the shift was 2.6 D (SD: 2.0) and 3.4 D (SD: 1.8), respectively (=0.098).
CONCLUSION
There was no relationship between the initial axial length and the myopic shift in all patients. Unilateral cataracts had a greater myopic shift over 3 years.
目的
确定先天性白内障手术联合一期人工晶状体植入术后3年的术前眼轴长度与近视漂移之间的关系以及其他相关因素。
方法
在这项回顾性队列研究中，测量眼轴长度并分为两组（>21.5 mm和≤21.5 mm），评估视轴遮挡、白内障的侧别、手术年龄和随访时间，并与近视漂移进行比较。
结果
所有患者的平均近视漂移为3.6（标准差[SD]：2.3）屈光度（D）；每组分别为3.2（3.3）和3.9（3.2）D（P=0.359）。单侧白内障的平均近视漂移为6.3 D，双侧白内障为3.0 D（P=0.001）。在双侧白内障中，漂移分别为2.6 D（SD：2.0）和3.4 D（SD：1.8）（P=0.098）。
结论
所有患者的初始眼轴长度与近视漂移之间无相关性。单侧白内障在3年内有更大的近视漂移。
