[The experience of the surgical treatment of astigmatism]

The paper analyses results after 133 operations on occasion of a simple, mixed and compound astigmatism; 4 methods of surgical correction were used: longitudinal, tangential, radial and combined. The analysis has shown that corneal astigmatism of different kinds and degrees can be corrected by different methods of anterior keratotomy. As a result of surgical treatment, the degree of refraction of both spherical and cylindrical, reduced and visual acuity with tolerant correction increased. The choice of the method depends on the kind and degree of astigmatism and the degree of the spherical ametropia of the operated eye.
