|The excimer laser can be used to reshape the cornea to correct farsightedness.
If your eye is farsighted (hyperopic) the cornea is flatter than is required given the
length of your eye. Hyperopic excimer laser surgery can improve your vision without
glasses by reshaping the front suface of the eye and making it more curved.
In hyperopic (farsighted) treatment, a "donut" of tissue is
removed from the mid-periphery of the cornea as shown in the picture above. This
changes the profile of the cornea to steepen the central curvature as pictured below.
