Abstract: Software for calculating an astigmatism treatment is operable upon execution to perform the following steps: receiving biometric information for a patient; determining based on the biometric information an astigmatic correction comprising at least one of (a) a position for one or more limbal relaxing incisions and (b) a power and an orientation for a toric intraocular lens (IOL); generating an output comprising the astigmatic correction; receiving a selection of a different ratio of astigmatic correction attributable to the one or more limbal relaxing incisions and the toric IOL; determining an updated astigmatic correction including at least one of (a) an updated position for the one or more limbal relaxing incisions and (b) an updated power and/or orientation of the toric IOL.

Abstract: Software for calculating an astigmatism treatment is operable upon execution to perform the following steps: receiving an initial primary incision position; determining a power and orientation for a toric intraocular lens (IOL) to treat an astigmatism of an eye based on the initial primary incision position; determining an adjusted primary incision position based on the power and the orientation for the toric IOL to further reduce the astigmatism; and generating an output comprising the adjusted primary incision position.

Abstract: A system and method of resecting corneal tissue for transplantation is disclosed. In each of the recipient cornea and the donor cornea, an annular incision is made at a predetermined incision depth. A first sidecut incision is made in each cornea, running from the outer periphery of the annular incision to one of the anterior corneal surface or the posterior corneal surface. The first sidecut incision forms an acute angle with the annular incision. A second sidecut incision is also made in each cornea, running from the inner periphery of the annular incision to the other of the anterior corneal surface or the posterior corneal surface. The second sidecut incision forms an acute angle with the annular incision. The combination of the incisions in each cornea resects corneal tissue from the recipient cornea and donor tissue from the donor cornea. The donor tissue is grafted into the recipient cornea.

Abstract: A system and method for resecting and transplanting corneal tissue is disclosed. In a recipient cornea, a resection depth from the anterior surface of the recipient cornea is determined based upon a biomechanical model of the recipient cornea. A resection incision for resecting a posterior portion of the recipient cornea is made at the resection depth. Preferably, the incision is made using a surgical laser. Optionally, a contact lens may be placed against the anterior surface of the recipient cornea, wherein the shape of the anterior surface is conformed to the shape of the contact lens.

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.

Abstract: A system and method for resecting corneal tissue is disclosed. A resection pattern is selected for resecting corneal tissue. The resection pattern is incised in a cornea using a surgical laser, leaving one or more uncut gaps in the incised resection pattern. Any uncut gaps left in the resection pattern may thereafter be incised using an alternate surgical instrument.

Abstract: A system and method for marking corneal tissue in a transplant procedure is disclosed. Sidecut incisions are made in each of the donor cornea and the recipient cornea. Crosscut incisions are made across the sidecut incision in each cornea. Corneal tissue which is at least partially bounded by the sidecut incision is resected from the recipient cornea. Part of the crosscut incision made in the recipient cornea extends beyond the resected corneal tissue. Donor tissue which is at least partially bounded by the sidecut incision is resected from the donor cornea. Part of the crosscut incision made in the donor cornea is in the resected donor tissue. The donor tissue is then grafted into the recipient cornea.
