In addition to improved vision, a further advantage of combining CXL with laser eye surgery is the quicker healing time as compared with standard CXL. The changes in the curvature of the cornea affects its refractive power, which will lead to astigmatism (distortion of vision), myopia (blurriness of vision) and/or increased sensitivity to light.
