Corneal astigmatism. The effect of transverse corneal incisions.
The results of transverse or combined transverse and radial keratotomy in eyes with idiopathic corneal astigmatism (N = 11), astigmatism+myopia (N = 9) or early stages of keratoconus (N = 6) are presented. The corneal astigmatism was reduced in all our patients, the absolute reduction being significantly correlated to the degree of preoperative astigmatism (p = 0.007). In the whole study group the mean relative reduction of the corneal astigmatism was 52.7%. In eyes without keratoconus the astigmatism recorded at the last follow-up visit was very similar to that measured a few days after surgery, while greater changes occurred in the keratoconus group.
