ABSTRACT:
A corneal drug delivery device that releases a drug contained in the corneal drug delivery device at a predetermined rate. The drug delivery device has an opening or aperture in the center substantially the size of the pupil and a diameter and curvature substantially the same as the cornea. The convex surface of the device is tapered to form a thin flexible inner edge around the central pupil aperture. The outer peripheral edge is also thin and flexible to allow the device to assume the shape of the cornea upon which it is placed.
