The long-term stability of laser vision surgery is remarkable. In our practice, we have seen patients retain excellent unaided vision (in the range of “20/20” and even “20/15”) for over a decade. Laser vision correction is at least 1,000 times more accurate, and more stable, than any prior corrective surgery ever performed, including radial keratotomy (“RK”). Excimer laser surgery was first performed in 1988. Extensive testing around the world has confirmed that there are no long-term health problems to the eye from this type of care.
