1. A delivery system for delivery of ophthalmic solutions to an eye, comprising:
an eye surface preparation sponge device comprising a handle and a head secured to the handle, wherein the head is formed entirely from a single absorbent, fast-wicking sponge material, wherein the head is configured to expand from a first configuration having a circular disk shape or part circular disk shape with opposite flat surfaces when dry to a second configuration different from the first configuration and having a spherical or part spherical shape when wetted, at least the second configuration having no sharp edges, and wherein the head includes an epithelial tissue preparation surface configured for rubbing across a curved surface of the epithelium of the eye to prepare the curved surface for penetration by an ophthalmic solution; and
a loading sponge for use in holding the ophthalmic solution against the curved surface of the eye, wherein the loading sponge comprises a size large enough to cover an entire cornea of the eye and a thickness of between 0.5 mm and 5 mm, wherein the loading sponge acts as a reservoir to hold the ophthalmic solution against the curved surface of the eye where treatment is needed over an extended time period, allowing efficient penetration of the ophthalmic solution into the cornea.
