Abstract. Purpose:To evaluate the efficacy of additional laser vision correction(LVC)for the residual refractive error after radial keratotomy(RK). Cases and Methods:Four eyes of two cases and seven eyes of four cases, who had previous RK, underwent photorefractive keratectomy and laser in situ keratomileusis, respectively. Patients, five men and one woman, ranged in age from 26 to 51 years old and the mean age was 37.5 years. LVC was performed as usual. Results:The mean uncorrected visual acuity after the surgery was 1.24(range, 0.8~1.5). Manifest refraction spherical equivalent(MRSE)was+0.05+/-0.70D(range, -0.75~+2.00D). Visual acuity and residual refractive error improved in all eyes. Epithelial ingrowth was observed in three eyes. Two of them were treated effectively by steroid eye drops and one eye required surgical removal. Conclusion:LVC is effective in treating refractive error after RK. However it carries the risk of characterized complications due to previous RK.
