Abstract

We measured the effects of pH changes after water washings of polymethylmethacrylate (PMMA) intraocular lenses sterilized in 10% sodium hydroxide (NaOH). Whereas inserting the base-sterilized lens directly into the eye causes a large pH change in the local area of the implant, three separate washings of the NaOH-treated implant in 15 ml of water eliminates this change. No buffer is required.

摘要

我们测量了在10%氢氧化钠（NaOH）中灭菌的聚甲基丙烯酸甲酯（PMMA）人工晶状体水洗后pH值变化的影响。将经碱灭菌的晶状体直接植入眼内会导致植入物局部区域的pH值大幅变化，而将经NaOH处理的植入物在15毫升水中进行三次单独冲洗可消除这种变化。无需使用缓冲液。
