Abstract: A method for delivering fluids, drugs, or medications to a patient's eye, and a system or apparatus for implementing the method, is disclosed. The system and method comprises the use of a corneal sponge to be deposited onto the cornea of the patient's eye while the patient's eyelids are maintained in open positions, and a scleral contact lens is disposed onto the sponge. The scleral lens has an irrigation fluid supply tube fluidically connected thereto for supplying a fluid, drug, or medication to the sponge which is saturated with the fluid, drug, or medication. Once the sponge and lens are inserted onto the corneal region of the eye, the patient's eyelids are closed thereby trapping and maintaining the sponge and lens upon the corneal region of the eye so as to permit the fluid, drug, or medication to be continuously supplied and applied to the corneal region of the eye.
