A 53-year-old man sustained a perforating, central corneal injury with a nail in his right eye. After primary repair of the laceration, a traumatic cataract was removed and a Multiflex-style intraocular lens (IOL) was inserted. A 4.00 diopter surprise resulted, probably due to calculation of the IOL power using measurements from the contralateral normal eye. Inability to wear a contact lens for visual correction resulted in IOL exchange surgery in which a sulcus-sutured IOL was implanted. The IOL power was calculated using simulated keratometry from videokeratoscopy and axial length measurements of the injured eye. This resulted in an IOL power closer to emmetropia, allowing for a best spectacle-corrected visual acuity of 20/20 and comfortable wearing of spectacles.
一名53岁男性右眼被钉子扎伤，导致中央角膜穿孔。在对伤口进行一期修复后，摘除了外伤性白内障，并植入了一枚Multiflex型人工晶状体（IOL）。结果出现了4.00屈光度的偏差，可能是因为使用对侧正常眼的测量值来计算IOL度数。由于无法佩戴隐形眼镜进行视力矫正，遂进行了IOL置换手术，植入了一枚经巩膜缝线固定的IOL。通过视频角膜曲率计模拟角膜曲率测量以及伤眼的眼轴长度测量来计算IOL度数。这使得IOL度数更接近正视，最佳矫正视力达到20/20，佩戴眼镜也很舒适。
