Radial Keratotomy (RK)
RK is a surgical procedure to correct mild myopia or nearsightedness. Before the Excimer laser was approved for PRK in 1995, RK was the only surgical method available to correct myopia. Since then, other refractive procedures such as LASIK, PRK and Visian ICL have evolved as preferred methods of myopia correction. In certain cases, Dr. Erdey still may recommend RK to correct residual myopia after a previous refractive procedure. RK is performed by making a series of tiny spoke-like scratches onto the cornea to change the curvature. By changing the corneal curvature the rays of light can be focused onto the retina to create sharper vision. The pattern of these tiny scratches varies and are placed specifically to correct your degree of nearsightedness. Mild eye drops are used to numb the eye for this short, fifteen (15) minute procedure.
Complications from Radial Keratotomy (RK) are not common. Dr. Erdey is a regional expert and pioneer in specialized techniques capable of potentially correcting severe corneal irregularity that may eventually develop in eyes that had RK many years ago.
