PURPOSE
To evaluate the refractive status, axial length, and refractive power of the cornea in pediatric patients after unilateral cataract surgery and intraocular lens implantation.
METHODS
Refractive state, refractive power of cornea, and axial length were measured both in the operated and nonoperated eyes in 15 patients (age at surgery = 5 to 15 years; mean, 10.3) before and 4 to 15 years (mean, 9.7) after unilateral cataract surgery.
RESULTS
After surgery, visual acuity was 20/40 or better in 79% of operated eyes. Myopic changes, representing the difference between postoperative refraction at last follow-up and postoperative refraction at 1 year after surgery, were noted in the operated eyes at the end of study (mean, -5.02 D), but there were no significant differences in axial length (Wilcoxon signed rank test P >.05) or refractive power of the cornea between operated and nonoperated eyes (paired Student t test P >.05).
CONCLUSION
Myopic shift after cataract surgery with intraocular lens implantation may occur even in older children.
目的
评估小儿单侧白内障手术及人工晶状体植入术后的屈光状态、眼轴长度和角膜屈光力。
方法
对15例患者（手术年龄5至15岁；平均10.3岁）在单侧白内障手术前及术后4至15年（平均9.7年）测量术眼及对侧未手术眼的屈光状态、角膜屈光力和眼轴长度。
结果
术后，79%的术眼视力达到20/40或更好。在研究结束时，术眼出现近视性变化，即末次随访时的术后屈光度与术后1年时的屈光度之差（平均-5.02 D），但术眼与未手术眼之间的眼轴长度（Wilcoxon符号秩检验P>.05）或角膜屈光力无显著差异（配对t检验P>.05）。
结论
即使是年龄较大的儿童，白内障手术联合人工晶状体植入术后也可能出现近视漂移。
