Abstract: A keratome includes a cutting instrument having a cutter head with a reciprocating blade and a cutting edge extending below a sole surface of the cutter head; an automated drive unit mounting the cutting instrument for powered translational movement of at least the cutter head thereof, and a suction ring including an eye ring adapted to be secured to an eye by suction and defining a cornea aperture for presenting the outer layer of the cornea of the eye for cutting.

Abstract: A user activated iontophoretic device of the present invention includes an electrode assembly, an electrode reservoir and at least one drug reservoir. The device is divided or otherwise separated into at least two portions, with one portion containing the electrode reservoir and the other containing the drug reservoir, which may include a medication in a dry form. In one embodiment, the two portions are each contained in separate compartments of a pouch. In another embodiment, the portions are contained in a single compartment and divided by a barrier. A method of activating the device includes causing the two portions to come into electrical conducting contact with one another to at least partially hydrate one of the reservoirs. This can be accomplished, for example, by either folding the device to bring the two portions into contact with one another or simply by removing the barrier dividing the two portions.
