1. A method of treating a cornea of an eye, comprising:
measuring a profile of a posterior portion of the cornea;
incising the cornea with a plurality of laser beam pulses to form an access incision and a tunneling incision in the cornea, wherein the access incision is sized to receive an elongate structure having a fluid passing channel, wherein the cornea is incised in response to the profile such that the tunneling incision extends a distance from a posterior surface of the cornea to a location of a posterior portion of the cornea;
inserting the elongated structure through the access incision into the tunneling incision; and
advancing a fluid along the fluid passing channel to separate a corneal tissue at the location and form a flap of tissue separated from the posterior portion of the cornea, the flap having a thickness corresponding to the distance.
