Abstract

Recently, a significant rise in the share of one-day contact lenses in global sales has been noted. In order to increase the interest in daily disposable contact lenses, manufactures have tried a range of product improvements. Soft contact lens material delefilcon A (Dailies Total 1) with water gradient technology deserves special attention. Delefilcon A is composed of a silicone- hydrogel core, with a 33% water content, and an outer hydrogel layer with an 80% water content. A number of advanced biomicroscopic techniques enable an accurate analysis of the layered structure of delefilcon A.
