Abstract
A cleaning solution for contact lenses is described that includes a carbohydrate that is a mono- or disaccharide, its alcohols or partially hydrolyzed esters or mixtures thereof. Preferred carbohydrates are sorbitol, glucose, maltose, sucrose, dulcitol, dextran, dextrin, mannitol, maltitol, or mannose, preferably in an amount of 0.001 to 10% by weight of an aqueous solution for cleaning the contact lenses. A preferred composition for cleaning contact lenses comprises sorbitol in an amount of about 0.1 to 1% by weight in an aqueous solution. A method for cleaning contact lenses with said carbohydrate cleaning solution is described and may be combined, for simultaneously cleaning and disinfecting contact lenses, with a chemical, antimicrobial agent or thermal disinfecting regimen.
