AIM: To assess the effectiveness and safety of transepithelial photorefractive keratectomy(TransPRK)using the AMARIS laser platform.

METHODS: Eighty myopic cases(156 eyes)with or without astigmatism were treated by TransPRK. In all eyes, treatments were planned with Custom Ablation Manager Software and ablations performed with the SCHWIND AMARIS system. Clinical outcomes of visual acuity, manifest refraction, intraocular pressure, and corneal topography were observed and analyzed. The follow-up period was one year.

RESULTS: All patients completed the 1-year follow-up. After one-year follow-up, 47 cases(92 eyes, 58.8%)achieved an uncorrected distance visual acuity(UDVA)≥1.0. Twenty cases(40 eyes, 25%)was 0.8 and 13 cases(24 eyes, 16.3%)was 0.6. Sixty-three cases(121 eyes, 78.8%)were close to or above best corrected visual acuity(BCVA). Seventeen cases(34 eyes, 21.2%)were slightly lower than BCVA 1 row or two. Nine cases(18 eyes, 11.3%)got dry eye postoperatively. 16 cases(32 eyes, 20%)complain of glare and poor night vision.

CONCLUSION: The results show that TransPRK for myopia with or without astigmatism is safe and effective. The postoperative visual outcomes are stable.
