目的：建立软性接触镜成品镜片透氧系数的检测方法。方法在市场上选择10种成品镜片，使用极谱法测定软性接触镜的透氧系数，并采用通过参考材料对应定制与被测镜片等厚的校准片的方法进行分段校准，据此测定软性接触镜成品片的透氧系数。结果10批镜片的透氧系数值除1片外，其余9批符合国标GB 11417.3—2012中关于透氧系数偏差不超过±20%的规定。结论极谱法测试中采用参考材料对应定制等同被测片厚度校准片进行校准的方法，可摆脱被测镜片定制4种不同厚度镜片的困难，对于测试软性接触镜成品片具有很大的实用性。

Objective A method for determined oxygen permeability(Dk) of finished soft contact lens. Methods Oxygen permeability(Dk) of 10 group finished soft contact lens was determined by polarographic method, and the values were linearly calibrated using the measured and established Dk values of the specified reference materials. Results Only one Dk value fel outside of the requirement of GB 11417.3—2012 tolerance for Dk(±20%). Conclusion It is great practicability when determined the oxygen permeability(Dk) of finished soft contact lens by polarographic method which were linearly calibrated using the measured and established Dk values of the specified equal thickness reference materials. without the measured lens customized 4 different thickness.
