ABSTRACT:
A method for refractive correction of the eye in order to improve the vision of the eye while not adversely affecting its natural asphericity is described. The method involves determining the amount of correction necessary, selecting an intrastromal corneal ring (ICR) of appropriate thickness to obtain the necessary correction from a selection of ICRs of varying thickness, and inserting the ICR into the corneal stroma. The method may be useful for the correction of myopia and excessive astigmatism.
