[Corneal astigmatism after refraction keratotomy].
Refraction keratotomy, by changing corneal refraction, may cause postoperative astigmatism, including its reverse form. The author suggests to assess astigmatism using astigmatic coefficient (K alpha), which is expressed as the cosine of the angle between the vertical and the direction of the stronger main meridian. Intra-and postoperative use of fibronectin solution is proposed to lower the K alpha and improve the efficacy of surgery.
