ABSTRACT:
The intrastromal corneal ring (ICR) of the invention has a flexible, preferably circular body sized and configured such that it can be inserted into a human eye and comprised of a material which is compatible with human ocular tissue. The end portions of the circular body overlap each other and are formed in several different configurations or embodiments. The end portions are preferably configured such that when allowed to come together they intermesh and provide a ring with a smooth and continuous outer profile.
