Abstract Details


To evaluate eye registration success, data and effect on the clinical outcomes in the treatment of myopic astigmatism using Schwind Amaris 1050RS and Wavelight EX-500


Alexandria University and ICare Hospital Alexandria EGYPT


Retrospective study. Subjects with myopic astigmatism seeking laser vision correction were treated using either the Schwind Amaris 1050RS (169 eyes) or Wavelight EX-500 (162 eyes). Data of eye registration during treatment were evaluated. Post-operative visual and refractive outcomes were studied.


The 2 groups were similar preoperatively in the refraction and visual acuity. With the Schwind Amaris, eye registration was successful in 87.6% of eyes (mean -0.37±2.94) versus 85% of eyes with the EX500 (mean -0.09±4.08). At 3 months postoperatively, mean UCVA was 1.09 ± 0.16 in the Schwind group compared to 0.99 ± 0.21 in the EX500 group. In eyes that had treatment with the Schwind Amaris, mean sphere and cylinder were 0.00 D ± 0.49 and -0.38 D ± 0.24 respectively, versus 0.17 D ± 0.5 and -0.43 D ± 0.24.


TheSchwind Amaris 1050RS and Wavelight EX-500 machines are equally effective in treating myopic astigmatism. The eye registration process seems to be more successful using the Schwind Amaris 1050RS system.
