Abstract Details


To compare, in a retrospective setting, 12 month postoperative follow-up outcomes of moderate vs. high myopic transepithelial photorefractive keratectomy (TE-PRK) corrections using SCHWIND AMARIS (SA).


Pacific Laser Eye Centre, Vancouver, BC, Canada


Retrospective case series. The outcomes of 446 myopic TE-PRK treatments performed with AMARIS evaluated at 12 month postoperatively. Analysis was divided into moderate (up to -8D, N=389) and high myopia (from -8D, N=44). Refractive and visual comparisons were performed in terms of refraction, uncorrected visual acuity (UCVA), corrected distance visual acuity (CDVA), and safety (change of CDVA from baseline).


12 month postoperative outcome: UCVA ≥20/20 achieved by 84% and 47% of the moderate and high myopia subgroups (p<0.0001); ≥20/40 achieved by 99% and 90% of the moderate and high myopia subgroups (p=0.001)); CDVA ≥20/20 achieved by 95% and 82% of the moderate and high myopia subgroups (p=0.001); astigmatism was 0.25±0.33D for moderate myopia versus 0.36±0.36D for high myopia, p=0.01; 14% and 28% of the moderate and high myopia subgroups gained lines of CDVA (p=0.02). No ≥2 lines loss of CDVA in either group. No postoperative differences observed in spherical equivalent. No retreatment was performed for either group.


Myopic PRK with Schwind Amaris at 12 month postoperative showed good outcomes with 84% achieving 20/20 UDVA in moderate myopia (up to -8D) and 47% in high myopia (higher than -8D). Excellent results are possible with transepithelial photorefractive keratectomy with Schwind Amaris for moderate and high myopia, and are an alternative to LASIK.
