摘要
多个眼科医疗器械行业标准在检测方法中都使用了环曲面测试面。本文从数学表达式及特性、临床用途和制作工艺方面对环曲面进行了介绍,并以《YY 0787-2010眼科仪器角膜地形图仪》中准确度的测试为例说明了环曲面的使用方法。
Many industry standards of ophthalmic medical instruments relate to the toric surface. The article introduces the mathematical equations, features, clinical applications and machining techniques of toric surface. What＇s more, a sample of testing the accuracy according to YY 0708 by using the toric surface is also shown.
