Advances in surgical techniques allow implantation of intraocular lenses (IOL) with cataract extraction, even in young children. However, there are several challenges unique to the pediatric population that result in greater degrees of postoperative refractive error compared to adults.
Literature review of the techniques and outcomes of pediatric cataract surgery with IOL implantation.
Pediatric cataract surgery is associated with several sources of postoperative refractive error. These include planned refractive error based on age or fellow eye status, loss of accommodation, and unexpected refractive errors due to inaccuracies in biometry technique, use of IOL power formulas based on adult normative values, and late refractive changes due to unpredictable eye growth.
Several factors can preclude the achievement of optimal refractive status following pediatric cataract extraction with IOL implantation. There is a need for new technology to reduce postoperative refractive surprises and address refractive adjustment in a growing eye.
手术技术的进步使得即使在幼儿中也能在白内障摘除时植入人工晶状体（IOL）。然而，儿科人群存在一些独特的挑战，导致与成人相比术后屈光不正的程度更高。
对小儿白内障手术联合IOL植入的技术和结果进行文献综述。
小儿白内障手术与术后屈光不正的多种来源相关。这些包括基于年龄或对侧眼状况的计划性屈光不正、调节功能丧失，以及由于生物测量技术不准确、使用基于成人标准值的IOL屈光力计算公式以及由于不可预测的眼球生长导致的后期屈光变化而出现的意外屈光不正。
几个因素可能妨碍小儿白内障摘除联合IOL植入后达到最佳屈光状态。需要新技术来减少术后屈光意外，并解决生长中眼睛的屈光调整问题。
