title: Myopic keratomileusis in situ combined with VISX 20/20 photorefractive keratectomy.
abstract: We present the results of myopic keratomileusis in situ combined with photorefractive keratectomy (PRK) in five eyes with high myopia and low astigmatism. Follow-up ranged from 10 to 12 months. A hinge was used to perform subtotal lamellar keratectomy and the spherical component of myopia was corrected by three-zone PRK. The mean preoperative spheroequivalent was -21.00 diopters (D) and the postoperative spheroequivalent was -1.50 D. In four eyes the best corrected visual acuity was unchanged or improved; in one eye it decreased because of epithelial ingrowth in the lamellar interface. Persistent oblique longitudinal folds were noted in the corneal disc in one eye, and induced cylinder was found postoperatively in one eye.
