Claims

2. A method of applying medication to the human eye comprising:

impregnating a member formed from a soft, liquid permeable plastic material and having a convex posterior surface with an eye medication;

positioning the impregnated member in the eye of a patient with the posterior surface of the member substantially engaging the cornea of the eye and thereby gradually releasing the eye medication from the member into the eye.
