W. Forster et al., CORRECTING MYOPIC ASTIGMATISM WITH AN AREAL 193 NM EXCIMER-LASER ABLATION, Journal of cataract and refractive surgery, 21(3), 1995, pp. 278-281
A new system to correct symmetric bow-tie myopic astigmatism with the
excimer laser using oval apertures for toric ablations is described. I
nitial results in two patients who had -5.0 and -5.5 diopters of astig
matism after surgery with six-months follow-up showed a reduction of u
p to 85% with a minimal axial error of two degrees.
