| 摘要 |
<p>The present invention is directed to a corneal implant comprising one or more physiologically compatible inserts adapted for implantation within an interlamellar channel made within the cornea of a mammalian eye. Each insert comprises a main section providing substantially all of the adjustment to the corneal curvature to thereby correct vision abnormalities. At least one of the inserts further comprises one or two migration preventing extension sections, each coupled to an end of the main section. After implantation within the intracorneal channel, the extension section extends from an end of the main section and is disposed near or abuts either the main section of another insert or an end of the intracorneal channel. The extension section serves as a stop to reduce or prevent migration of the one or more inserts after implantation within the intracorneal channel.</p> |
