Radial keratotomy reduces the strength of the cornea front of a trauma by blast. The authors present and analyze the case of a 25-year-old patient having been submitted to an ocular bilateral trauma by explosion. Twenty-two months earlier he had undergone radial keratotomy (RK) in the left eye followed 8 days later by photorefractive keratectomy (PKR) in the right eye for a -6,00 d. myopia RLE. Though the trauma by blast essentially reached the right eye, the corneal anatomical damages were more important in the left eye. This is according to us the first case report of trauma on eye subjected to PRK. We appreciate the clinical differences presented by each eye.
