Because breadths of surgical blades are very difficult to measure directly, we designed a method to measure sharpness of a variety of instruments by determining the power they required to incise corneal tissue to a uniform depth. Diamond knives were the sharpest, followed by razor blade pieces individually prepared by a special new method. Ruby knives varied considerably. The method of measuring sharpness described may allow manufacturers to improve and stabilize production methods, as well as enable surgeons with such knowledge in advance of surgery to optimize wound healing and maximize cost-effectiveness.
由于手术刀片的宽度很难直接测量，我们设计了一种方法，通过确定各种器械将角膜组织切割到均匀深度所需的功率来测量其锋利程度。钻石刀最锋利，其次是用一种特殊新方法单独制备的剃须刀片。红宝石刀的差异很大。所描述的测量锋利度的方法可能使制造商改进并稳定生产方法，还能使外科医生在手术前掌握此类知识，从而优化伤口愈合并实现成本效益最大化。
