What is radial keratotomy (RK) in relation to LASIK?

ANSWER

Radial keratotomy (RK) was the first refractive surgery used in the U.S. It has been largely replaced by LASIK surgery. A variant of RK -- limbal relaxing incision or arcuate keratotomy -- may be chosen to correct mild astigmatism. The eye surgeon uses a diamond scalpel to make cuts on the cornea. In RK, these cuts flatten and reshape the cornea. RK weakens the eye's structure over time, resulting in fluctuation in vision and long-term instability, the primary reasons it is seldom done now.
