Inclusion criteria were myopia of\u2009\u2212\u20090.5 D or more and astigmatism between\u2009\u2212\u20091.0 D and \u22125.0 D. Refractive and visual measurements were obtained preoperatively, 1 and 12 month(s) postoperatively. Vector analysis was used to study the astigmatic outcomes at 12-month follow-up. Comparison of results in two groups of patients with astigmatism below and over 3.00 D was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The preoperative mean spherical equivalent was \u22125.48\u2009\u00b1\u20092.17 D (range\u2009\u2212\u20091.75 to\u2009\u2212\u200910.00 D) and the mean cylinder was \u22122.02\u2009\u00b1\u20091.09 D (range\u2009\u2212\u20091.00 to\u2009\u2212\u20095.00 D). The mean postoperative cylinder value was \u22120.60\u2009\u00b1\u20090.52 D at 12-month visit. The 12-month safety and efficacy indices were 0.98\u2009\u00b1\u20090.07 and 0.97\u2009\u00b1\u20090.12, respectively. The high astigmatism group showed significantly lower safety and efficacy indices. The postoperative residual astigmatism was 0.5 D or less in 73% of the eyes. Higher amount of residual astigmatism was observed in the high astigmatism group. The angle of error was\u2009\u00b1\u20095 degrees in 49% and\u2009\u00b1\u200915 degrees in 87% of the eyes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>SMILE surgery is effective and safe method for correcting myopic astigmatism.
