To evaluate the effect of phototherapeutic keratectomy combined with photorefractive keratectomy in the treatment of myopia with corneal scars, corneal epithelium was removed with laser plus scraping. Corneal scars were removed with PTK, followed by PRK for myopia. Healon was used to make corneal surface smoother during operation. 30 eyes of 24 cases of myopia with corneal scars were followed up for one year. Mean corrected vision was 0.51 and myopic degree was -6.42 D +/- 4.26 D before operation. After operation, corneal scars of 21 eyes (70.0%) were removed in operative zone. The vision of 27 operated eyes (90.0%) was equal to or better than best corrected vision. Mean postoperative visual acuity was 0.72. Corneal surface was smoother and astigmatism was reduced after the surgery. Our study showed that PTK combined with PRK is a safe and effective treatment for myopia with corneal scars.
