Eye doctors who fit contact lenses know that discomfort is the chief culprit behind dropout. To help, Bausch + Lomb designed its newest lens, called Infuse, to be as minimally disruptive to the tear film as possible, according to a company press release.
A silicone hydrogel lens, Infuse also includes two osmoprotectants (erythritol and glycerin) and potassium, an electrolyte. Having these moisturizers infused in the lens material inspired the choice of brand name. B+L calls these additions “ProBalance Technology” in its marketing and says they help retain hydration, provide a smooth, wettable surface and maintain tear proteins in a healthy state.
The choice of these agents was prompted by the findings of the Tear Film and Ocular Surface Society’s Dry Eye Workshop II report, which characterized dry eye as a loss of ocular surface homeostasis. The result, according to B+L, is a contact lens that maintains 96% of its moisture for 16 hours.
Infuse is available in powers of -12D to +6D, with half-diopter steps in the -12D to -6D range and quarter-diopter steps thereafter. The material, kalifilcon A, has a Dk/t of 134 and a 55% water content.
