Device, system, and method for epithelium protection during cornea reshaping
First Claim
1. A device, comprising:
- a suction ring operable to attach the device to an eye, the eye comprising a cornea; and
a window operable to contact at least a portion of the cornea, the window substantially transparent to light energy that irradiates the cornea during a cornea reshaping procedure, the window also operable to cool at least a portion of a corneal epithelium in the cornea during the cornea reshaping procedure.

Abstract
A system includes a light source operable to generate light energy for a cornea reshaping procedure. The system also includes a device operable to be attached to an eye having a cornea. The device includes a window operable to contact at least a portion of the cornea. The window is substantially transparent to the light energy that irradiates the cornea during the cornea reshaping procedure. The window is also operable to cool at least a portion of a corneal epithelium in the cornea during the cornea reshaping procedure. The window may be operable to prevent clinically significant damage to the corneal epithelium during the cornea reshaping procedure. The window may be operable to prevent a temperature of the corneal epithelium from exceeding a damage threshold temperature during the cornea reshaping procedure, such as a damage threshold temperature of approximately 70° C.

39. A method, comprising:
-
attaching a device to an eye, the eye comprising a cornea, the device comprising a window operable to contact at least a portion of the cornea;
irradiating at least part of the cornea using light energy that passes through the window during a cornea reshaping procedure, the window substantially transparent to the light energy; and
cooling at least a portion of a corneal epithelium in the cornea using the window during the cornea reshaping procedure.
