  • Title: Repeated radial keratotomy.
    Author: Hu Y, Liu P, Qi L, Li X, Wu X, Li L.
    Journal: Zhonghua Yan Ke Za Zhi; 1995 May; 31(3):192-9. PubMed ID: 7555401.
    Abstract:
    38 cases 59 eyes received repeated radial keratotomy in which the secondary incisions were performed along the scars of old incisions. The average follow-up after the reoperation was 13 months. Before reoperation, the mean spherical equivalent of the refraction was -3.78D and the mean keratometry was 40.15D. 13 months after the reoperation, the mean spherical equivalent of the refraction decreased by 2.30D, and the mean keratometry decreased by 2.04D. After the reoperation, the mean uncorrected visual acuity increased by 5 lines. There was no relationship between the therapeutic effect of the reoperation and the degree of initial myopia or pre-reoperative keratometry. The repeated radial keratotomy can decrease the degree of astigmatism and its complications are few.
