| titleOfInvention | Corneal template and surgical device for refractive vision correction |
| abstract | A method for the selective removal of corneal tissue, and change of curvature thereof, for refractive vision correction, by means of a correction template in conjunction with a planar cutting high pressure water jet micro-keratome. The correction template is adapted to provide a planar cutting guide, on the corneal tissue, for the refractive correction required, with the template being shaped with a non-planar surface of predetermined configuration (related to the desired correction). The non-planar surface of the template is fitted to the area of the cornea to be refractively corrected, whereby the corneal tissue to be removed is selectively deformed so as to be substantially conformed to and held against the non-planar surface. Application of a vacuum between the template and cornea aids in this holding. The water jet micro-keratome, in a sheet-like configuration provides a full non-scanning transverse planar cut through the corneal tissue at a position adjacent the template, such that release of the template from the corneal tissue results in the undeformed configuration thereof having the desired correction. Use of the water jet micro-keratome provides a cut corneal tissue surface of smoothness and polish, substantially equivalent to that of the original surface. A device for the cutting of anterior corneal tissue of a subject's eye for any of therapeutic excision and refractive vision correction, said device comprising: a template adapted specifically to be placed and centered on an anterior portion of the corneal tissue to be removed, whereby the template comprises a surface therein to which the anterior portion, to be removed, is adapted to be fitted and deformed by such fitting, the deformation being predeterminately controlled, such that the interior surface to be cut, at the base of the anterior portion assumes a planar configuration, which is accessible for the cutting thereof, beyond an end of the template, wherein the anterior portion is defined between anterior and posterior surfaces and wherein the surface of the template has a height relative to a plane at the end of the template equal to the computed difference, point by point, of the difference in height between the anterior and posterior surfaces of the portion of the corneal tissue which is to be removed; and micro-keratome cutting means comprised of a high speed water jet. |
