Preoperative and postoperative BCVA and minus cylinder power of refractive astigmatism in G1 and G2. Significant improvement in BCVA was observed in both groups (a: G1, c: G2) (**p < 0.001, paired t-test). Significant reduction in minus cylinder power of refractive astigmatism was observed in both groups (b: G1, d: G2) (**p < 0.001, paired t-test). G1 = normal corneal astigmatism group, G2 = post-penetrating keratoplasty astigmatism group, BCVA = best corrected visual acuity
