Corneal stiffening for treating astigmatism
Methods are provided for treating astigmatism in an eye of a patient. An axis of greater curvature of the eye is determined. A stiffening process is applied to a cornea of the eye in a pattern defined from the axis of greater curvature of the eye.
1. A method for treating astigmatism in an eye of a patient comprising:
determining each of an axis of greater curvature of the eye and a magnitude of the astigmatism;
applying a first stiffening process to a cornea of the eye in a pattern defined from the axis of greater curvature of the eye and with an intensity defined from the magnitude of the astigmatism, the pattern being substantially symmetrical around the axis of greater curvature; and
applying a second stiffening process in a homogenous manner across substantially the entire cornea to stabilize the cornea after the first stiffening process.
