В статье рассмотрены вопросы важности кислородопроницаемости (Dk) в газопроницаемых материалах для контактных линз, а также важность высокого значения Dk для склеральных и ортокератологических линз.

In this article, we will examine the importance of oxygen permeability (Dk) in gas permeable contact lens materials, and the significance of high Dk in scleral and ortho-k lens designs.
