Six eyes (five patients ) with granular corneal dystrophies underwent photogherapeutic keratectomy (PTK) to ablate corneal opacities with using of two excimer lasers (Summit ExciMed UV 200LA and Visx Star).Follow-up range was from 6 months to 7 years (mean 3 yrs). And 5 patients were improved their corrected vision upto 20/20(20/40-20/20) within a few month after PTK except of one patient who received lamellar keratoplasty on both eyes in 15 yrs ago,underwent again two times PTKs on right eye on 14 yrs and 15 yrs later due to recurrences.There is no doubt that PTK is an advantageous and initial choice of treatment for vision improvement of granular corneal dystrophy instead of corneal grafting. Only one eye among six eyes was only developed to recurrent case.
