Abstract Details


To analyze the refractive and visual outcomes after Fs-SBK procedure for myopic astigmatism.


«Astana Vision» clinic, Astana city, Republic of Kazakhstan.


58 consecutive cases of Fs-SBK of 29 patients with myopic astigmatism less than 5.00 D (1 group) and 5.00 D or more in the fellow eye (2 group) was performed with 6 months follow-up. Excimer laser Allegretto 400 Hz and femtosecond laser FS-200 was used. PreOp mean MRSE was -8.78 D (up to -17.00 D) with mean astigmatism -3.44 D (up to -4.75 D) in group 1 and mean MRSE -9.04D (up to -17.38 D) with mean astigmatism -5.66 D (up to -7.25 D) in group 2. PreOp BCDVA in group 1 was 0.62 and 0.45 in group 2.


PostOp mean MRSE in group 1 was equal to -0.11 D and -0.22 D in group 2. Target Induced Astigmatism coincides with the Surgically Induced Astigmatism (p≤0,01). Index of Success (IOS) was 86.85% in group 1 and 91.26% in group 2 (p≤0.01). In 19 cases in group 1 and 20 cases in group 2 IOS was 100%. NCDVA in group 1 and in group 2 PostOp was: 0.83 and 0.72, respectively. Lines of PostOp NCDVA gained against PreOp BCDVA in 55% of cases in group 1 and in 83% of cases in group 2. Safety was 100%.


High refractive and visual outcomes of Fs-SBK procedures in the correction of myopic astigmatism had received. Only in 3 cases in group 1 and in 2 cases in group 2 in the PostOp period from 3 to 4 months enhancement by lifting the flap were performed.
