Effect of disagreement between refractive, keratometric, and topographic determination of astigmatic axis on suture removal after penetrating keratoplasty

Table 3

Best corrected visual acuity change and vector corrected change in astigmatism after suture removal. There was no significant difference in the vector corrected change in astigmatism between patients where visual acuity decreased and did not decrease (remained same or improved) following suture removal

Visual acuity Refraction
Mean (SD)
Keratometry

Topography

Decreased (n=6) 4.61 (2.83) 4.22 (1.81) 3.08 (1.42)
