Abstract
The major challenge these days in pediatric cataract surgery is not the technique of surgery or intraocular lens (IOL) used but the postoperative refractive error. Amblyopia occurring due to postoperative refractive error which the child has; destroys the benefit obtained by a near-perfect and timely surgery. Even if we settle the debate as to what should be the ideal postoperative target refraction, there is a postoperative surprise that is not explained by our conventional insights of an accurate power calculation in children. The role of IOL power calculation formulae in affecting the postoperative refractive error should not be underestimated. Therefore, which age-appropriate formula is to be used for children is unclear. This review is an update on major IOL power calculation formulas used in pediatric eyes. We have tried to define why we should not be using these formulas made for adult eyes and review the literature in this regard.
摘要
如今小儿白内障手术面临的主要挑战并非手术技术或所使用的人工晶状体（IOL），而是术后屈光不正。由于患儿术后屈光不正而发生的弱视，会破坏近乎完美且及时的手术所带来的益处。即便我们解决了关于理想术后目标屈光的争论，仍存在一种术后意外情况，这是我们基于对儿童准确屈光度计算的传统认知所无法解释的。IOL屈光度计算公式对术后屈光不正的影响作用不可低估。因此，尚不清楚该为儿童选用哪种适合其年龄的公式。本综述是对小儿眼科主要IOL屈光度计算公式的更新。我们试图阐明为何不应使用为成人设计的这些公式，并对这方面的文献进行综述。
