There are many children who have subnormal vision in spite of successful cataract surgery and aphakic spectacle lenses. There are children who have lens opacities for whom the state of aphakia would not be an improvement. Careful evaluation of functional vision, careful refraction, and the prescription of high adds or other optical devices are part of complete ophthalmological care for every one of these children. The dioptric strength of the reading add is determined by the functional reading vision and the calculation of the reciprocal of the visual acuity. It is also important to realize that many children who have lens opacities do not require special aids; functional vision is adequate until their accommodative reserve wanes with age. Continuous-wear contact lenses may eventually replace spectacle corrections for the aphakic child.
尽管白内障手术成功且佩戴了无晶状体眼镜片，但仍有许多儿童视力低于正常水平。有些儿童存在晶状体混浊，对于他们来说，无晶状体状态并不会有所改善。对这些儿童中的每一个进行全面眼科护理时，仔细评估功能性视力、仔细验光以及开具高附加值镜片或其他光学装置的处方都是其中的一部分。阅读附加镜片的屈光度由功能性阅读视力和视力倒数的计算来确定。同样重要的是要认识到，许多有晶状体混浊的儿童并不需要特殊辅助工具；在他们的调节储备随着年龄增长而减弱之前，功能性视力是足够的。连续佩戴隐形眼镜最终可能会取代无晶状体儿童的眼镜矫正。
