Abstract:
1. An apparatus comprising: a memory configured to store at least one model, the at least one model associated with a cornea reshaping procedure that comprises irradiating multiple spots on a cornea of a patient's eye through a heat sink so that depressions form at the spots and change a shape of the cornea, the heat sink comprising a window configured to contact at least a portion of the cornea of the patient's eye, the window configured to cool at least a portion of a corneal epithelium in the cornea during the cornea reshaping procedure, each spot associated with an amount of stromal collagen; and a processor configured to determine one or more treatment parameters for the cornea reshaping procedure using the at least one model, wherein the one or more treatment parameters comprise one or more of: an irradiation wavelength, an irradiation power, a spot size, and a duration of irradiation; the processor configured to determine the one or more treatment parameters in order to at least partially achieve a desired shape change to the cornea of the patient's eye with no more than 5% of the stromal collagen in the irradiated spots undergoing clinically significant shrinkage as a result of the cornea reshaping procedure; wherein the heat sink is configured to prevent a corneal wound healing response from being triggered as a result of the cornea reshaping procedure; and wherein the processor is configured to determine the one or more treatment parameters so as to prevent permanent opacifications from forming in the cornea of the patient's eye.
