Objective To report the results of 12 months' follow‐up of patients with myopia treated with excimer laser photorefractive keratectomy. Design A prospective study of patients undergoing excimer laser photorefractive keratectomy for myopia was commenced in September 1991. The study included 50 eyes (38 patients) with preoperative myopia of ‐1.50 to ‐6.00 dioptres and a maximum astigmatism of 0.75 dioptres. Results Forty‐six (92%) of the 50 eyes had an uncorrected acuity of 6/6 or better at 12 months, and 49 eyes (98%) had 6/12 or better. No patients had lost their best corrected acuity at 12 months. Forty‐five eyes (90%) were within 0.50 dioptres of emmetropia and 47 eyes (94%) were within 1.00 dioptre of emmetropia. Conclusions Excimer laser photorefractive keratectomy is a safe and predictable procedure for low to moderate myopia. It will increasingly be offered to patients as an alternative to the use of spectacles and contact lenses. (Med J Aust 1993; 159: 535‐538)
