[The follow-up survey of results of radial keratotomy].
We reviewed 119 cases of consecutive radial keratotomies of 67 patients who were followed up for three years to evaluate the stability and safety of the surgery. The average change of overall refraction was -0.12D between one year and three years after the surgery, which was statistically insignificant. Stable refractive results were achieved in 72.3% of the eyes. 16.8% of the eyes experienced an increase from -1.00D to 2.50D, and 10.9% displayed a decrease from 1.00D to 3.50D. Eyes with preoperative high myopia were more likely to cause significant postoperative refractive change. In three years, 8.5% of the eyes gained the best corrected visual acuity of two to four lines. 2.6% of the eyes lost two lines because of macular disorders. Specular microscopy indicated that there was no significant change in corneal endothelial cell density following radial keratotomy.
