Even with healthy growth in the number of contact lens (CL) options on the market, one particular burden continues to dog the industrycontact lens discomfort (CLD). What is clear is that, with the expanded range of silicone hydrogel lenses on the market, including the introduction of custom-made lenses (sifilcon A, CIBA VISION), several options exist for most contact lens wearers. A number of new options have recently come to market in this category. The objective of the study is to compare the overall subjective comfort profile over 8 hours of lens wear in two groups of habitual soft contact lens wearers (daily disposable hydrogel lenses and frequent replacement lenses) when refitted in to somofilcon A lenses.
