Popis: Purpose To analyze the retreatment rate between patients with low myopic astigmatism versus patients with high myopic astigmatism; all of them treated with Femtosecond Laser- Assisted Sub-Bowman Keratomileusis ( FSBK ). Methods To analyze the retreatment rate between patients with low myopic astigmatism versus patients with high myopic astigmatism; all of them treated with Femtosecond Laser- Assisted Sub-Bowman Keratomileusis ( FSBK ). Results The preoperative mean data were: Group I: Sphere was –3.98  2.09. Cylinder was –0.44  0.3 and best corrected visual acuity ( BSCVA ) was 1.15  0.1. Group II: Sphere was –3.66  2.54. Cylinder was –2.41  0.87 and BSCVA was 1.00  0.1. Three months after FSBK: The mean postoperative uncorrected visual acuity ( UCVA ) remained slightly higher in group I ( 1.08  0.2 ) than in group II ( 0.88  0.2 ) with p  0.001. The mean sphere was + 0.02  0.4 in group I and + 0.11  0.5 in group II ( p  0.009 ), and the mean cylinder was statistically significant superior ( p  0.0001 ) in group II ( -0.55  0.6 ) than in group I ( -0.11  0.2 ). This is correlated with the retreatment rate found, which was 26.9% ( 110 eyes) in group II and 6.48% ( 28 eyes ) in group I ( p  0.0001 ). Conclusion In patients with primary myopic astigmatism treated with FSBK, we found an statistically significant higher rate of enhancements in eyes with high myopic astigmatism ( 26.9 % ) than in eyes with low myopic astigmatism ( 6.48 % ).
