Arcuate keratotomy is a surgical procedure
on the cornea
of the eye.
This is implied by the term "arcuate keratotomy" because the part "kerato-" refers to the cornea, as is also true of other terms in this section (listed on the left).
In the case of arcuate keratotomy, a curved incision is made at the periphery (edge) of the cornea. This is often made in an area of greatest curvature of the cornea in order to flatten that part of the cornea to reduce astigmatism. In very simple terms, astigmatism is a defect of vision in which the image of an object is distorted because not all rays of light from the object are focussed, e.g. horizontally or vertically - see astigmatism for a more detailed explanation.
