Abstract
A system and method for preparation of donor corneal tissue is disclosed. The system includes two surgical lasers. The first surgical laser is adapted to incise a recipient cornea to enable resection of recipient corneal tissue. The second surgical laser is adapted to incise a donor cornea to enable resection of donor corneal tissue. Both surgical lasers are adapted to make corneal incisions which are defined by incision parameters. Further, both surgical lasers are calibrated to make substantially precise corneal incisions when provided with identical incision parameters.
Claims8
A method of preparing donor corneal tissue for transplantation, the method comprising:
- calibrating a first surgical laser and a second surgical laser, wherein both the first surgical laser and the second surgical laser are adapted to make corneal incisions defined by incision parameters and, when calibrated, are adapted to make substantially precise incisions when provided with identical incision parameters;
- providing a plurality of incision parameters for identification of first incision parameters, wherein the first surgical laser is adapted to incise the recipient cornea according to the first incision parameters;
- transferring the first incision parameters to the second surgical laser;
- and
- incising the donor cornea according to the first incision parameters using the second surgical laser to enable resection of donor corneal tissue.
A method of transplanting corneal tissue, the method comprising:
- calibrating a first surgical laser and a second surgical laser, wherein both the first surgical laser and the second surgical laser are adapted to make corneal incisions defined by incision parameters and, when calibrated, are adapted to make precise incisions, when provided with identical incision parameters, to within a predetermined tolerance;
- providing a plurality of incision parameters for identification of first incision parameters, wherein the first surgical laser is adapted to incise the recipient cornea according to the first incision parameters;
- transmitting the first incision parameters to the second surgical laser;
- providing a plurality of alteration parameters for identification of first alteration parameters, wherein the second surgical laser is adapted to alter the first incision parameters according to the first alteration parameters;
- incising the donor cornea according to the altered first incision parameters, using the second surgical laser, to enable resection of donor corneal tissue;
- incising the recipient cornea according to the first incision parameters, using the first surgical laser, to enable resection of recipient corneal tissue;
- resecting the donor and recipient corneas;
- and
- grafting the donor corneal tissue into the recipient cornea.
