Patent ID: 7001607

Claim:
Method for the treatment of an eye of a mammal, the eye having a conjunctival sac comprising the steps of: a. preparing a sterile polyaphron gel comprising at least one water-soluble fluorinated surfactant in a concentration lower than critical micellae formation, water and one homopolar component in an amount greater than 60% by weight selected from the group consisting of partially fluorinated fluorocarbon compounds of the general formula R F R H , R F R H R F , fluorocarbon oligomers of the type (R F ) X R H , silicone oil, and mixtures thereof; b. introducing the sterile polyaphron gel into the conjunctival sac of the eye to form a gel-like reservoir whereupon at each blink of the eye, a portion of the sterile polyaphron gel irreversibly liquefies under the effect of the shear forces caused by the blink, extrudes from the conjunctival sac and spreads over the cornea of the eye as a thin liquid film functioning as a tear substitute.
