Abstract
This invention is an improved method and kit for producing a desired channel or pathway in the interlamellar space in the corneal stroma for inserting a bio-compatible material. The method involves the use of clockwise and counter-clockwise dissectors and optionally channel connectors and finish channel connector.
Claims22
A method for forming intrastromal space in the cornea of an eye for inserting biocompatible material therein, said method comprising the steps of:
- (a) cutting a small incision into the corneal stroma;
- (b) inserting a counterclockwise dissector blade into the incision and rotating it counterclockwise to form a counterclockwise channel having a first end and a second end;
- and
- (c) inserting a clockwise dissector blade into the incision and rotating it clockwise to form a clockwise channel having a first end and a second end;
- wherein the first end of the counterclockwise channel and the first end of the clockwise channel are located at the incision, and wherein the second end of the counterclockwise channel does not adjoin the second end of the clockwise channel.
A method of inserting a biocompatible polymer into the corneal stroma of an eye, said method comprising the steps of:
- (a) cutting a small incision into the corneal stroma;
- (b) inserting a counterclockwise dissector blade into the incision and rotating it counterclockwise to form a counterclockwise channel having a first end and a second end;
- (c) inserting a clockwise dissector blade into the incision and rotating it clockwise to form a clockwise channel having a first end and a second end;
- and
- (d) inserting a biocompatible polymer into at least one of said channels
- wherein the first end of the counterclockwise channel and the first end of the clockwise channel are located at the incision, and wherein the second end of counterclockwise channel does not adjoin the second end of the clockwise channel.
A method for forming space in a cornea for inserting therein biocompatible material, comprising the steps of:
- (a) forming a first channel in the cornea in a first circumferential direction;
- (b) forming a second channel in the cornea in a second circumferential direction;
- wherein the first channel is non-intersecting with the second channel.
