1 900 consecutive eyes that underwent radial keratotomy by the senior author were evaluated retrospectively. 3 months after surgery, minimum reduction in mean spherical equivalent of 0. 67D was achieved with 1 incision and maximum 7. 250 with 24 incisions. Unconnected visual acuity of 20/40 or better was obtained in 99. 4% of eyes with low myopia, 64. 2% with moderate myopia and 32. 4% with high myopia. For anisometropia, bilateral RK reduced refractive error from -12. 12D to -5. 22D in more myopic eyes...
