Abstract
This invention is a surgical device for producing a circular, interlamellar channel within the corneal stroma. An intracorneal ring can be implanted into this channel at the corneal periphery modifying the corneal curvature while sparing the important central optical zone of the cornea. This channel is formed by the sequential use of two separate instruments. The first instrument, the channel-guide dissector, is a circular dissecting instrument which is a split ring dissector with the dissecting end having a blunt tip and the other end connected to a handle. The important aspect of this channel-guide dissector is that it has a relatively narrow width which results in production of a lamellar corneal channel that is typically too narrow for the insertion of a typical intracorneal ring for myopic adjustment.
