[Long-term results of radial keratotomy (RK)]

Among myopic patients performed RK with operative parameters stipulated by the authors' own computer software, 77 cases (152 eyes) were followed up over 1 year to find that 68% of the eyes with preoperative myopia of < or = -6.00DS attained visual acuity of 1.0 or better, and incision depths over 80% of the corneal thickness were conducive to long-term good effects: hence accurate determination of the corneal thickness was very important. In view of the limitations of RK, the authors suggested indications and contraindications for the procedure.
