ARTIFICIAL TEAR COMPOSITION ADAPTED TO BE USED WITH CONTACT LENSES

摘要

An aqueous artificial tear/rewetting drop solution is described. The solution may be utilized as both an artificial tear for persons wearing contact lenses and as a contact lens rewetting drop. The solution is based on the use of a citric acid/sodium citrate buffer system to prevent binding or other complexation between cationic antimicrobial preservatives and soft contact lenses, thereby making it possible to apply the solution directly to contact lenses while the lenses are being worn.
