We present a patient who was dissatisfied with the refractive results of the radial keratotomy procedure he had 8 years previously, specifically the instability of the visual acuity and refractive error throughout the day. To reverse the biomechanical disturbance caused by the incisions, an intracorneal ring segment (Intacs, Addition Technology, Inc.) was inserted in the inferior cornea. The variation in refraction decreased from 1.50 and 2.25 diopters (D) to 0.25 and 0.50 D, resulting in a very satisfied patient.
