    Journal: J Fr Ophtalmol; 1995; 18(6-7):455-60. PubMed ID: 7560787.
    Abstract:
    Photorefractive keratectomy (PRK) was performed with Excimer Laser after undercorrected radial keratectomy in 21 eyes of 15 patients (maximum 8 incisions, 3 mm optical zone). There was at least a 6-month interval between the two procedures. At the time of PRK, the mean age of the patients was 31 years and the mean spherical equivalent -2.3 D. Mean follow-up after PRK was 7.5 months; 10 eyes were followed for more than one year. Quite satisfactory results were obtained since PRK was effective in 88% (eyes with uncorrected visual acuity of 20/40 or better); predictability at +/- 1 D was 89%. Stable refractiveness was achieved at 3 months. The procedure is safe: there was no loss of best corrected visual acuity nor haze at one year. Other means of treating for undercorrection after refractive keratectomy were discussed in comparison with this technique.
