MINIMIZING BIOLOGICAL LIPID DEPOSITS ON CONTACT LENSES.

摘要

Method for minimizing the sorption of tear lipids on frequent replacement, or extended-wear, contact lenses, the method comprising (a) contacting the contact lens selected from the group consisting of senofilcon A, lotrafilcon A, lotrafilcon B, and comfilcon A B with a lens care solution for a period of at least three hours to minimize the accumulation of tear lipids on the contact lens. The lens care solution comprises 0.5 ppm to 10 ppm α-[4-tris(2-hydroxyethyl)-ammonium chloride-2-butenyl]poly[1-dimethyl ammonium chloride-2-butenyl]-ω-tris(2-hydroxyethyl) ammonium chloride; citrate, citric acid or a mixture thereof; and 0.005 wt.% to 0.05 wt.% hyaluronic acid. The method also includes(b) inserting the soaked contact lens into one's eye, and (c) repeating steps (a) and (b).
