    This study was performed to evaluate clinical effects of photorefractive keratectomy(PRK) using flying spot excimer laser in hyperopia and/or presbyopic patients. Fourteen patients(24 eyes) were treated with flying spot excimer laser refractive surgery. The target refraction was spherical equivalent(SE) -0.25to +0.25 diopter(D) for distance vision and SE -0.75 to -2.00D for near vision. Follow-up visits occurred 1 week, 1, 3, 6 and 12 months after surgery. One year after PRK, 11 eyes(46%) had a refractive error within ?0.5D of target refraction, 19 eyes(79%) were within ?1.0D. The average distance visual acuity and near visual acuity were 0.02?0.08 log MAR and 0.31?0.06 log MAR respectively. All eyes had postoperative uncorrected visual acuity of 20/40 or better and 22 eyes(92%) showed 20/25 or better. There was no case of induced astigmatism. In conclusion, PRK with flying spot excimer laser would be sufficient to treat hyperopia and presbyopia in an effective and predictable way.
