ABSTRACT:
Methods are disclosed for adjusting corneal curvature to correct the refractive error of an eye. The method comprises a first corrective event in which the corneal curvature is adjusted to correct the eye to 20/20 vision or slightly over-correct the eye past 20/20 vision. After the first corrective event, a second corrective event adjusts the corneal curvature to 20/20 vision. The second corrective event causes significantly less trauma to the eye, and thus, compared to the first corrective event, the error from healing and other factors is greatly reduced in this second corrective event. Devices for implementing these methods are also disclosed.
