title: [Surgical correction of astigmatism using kerato-resection methods].
abstract: The authors analyze the results of surgical correction of hypermetropic and mixed astigmatism, carried out by two methods: clinoid resection of the cornea and clinoid resection of the cornea with tangent autoclinoplasty (i. e. implantation of the resected site to the tangent incision in strongly refracting meridian). Surgical technique has been mastered in experiments with isolated eyes and the mechanism of changes in corneal refraction, resultant from its resection, studied. Experiments with rabbit eyes have shown that after corneal resection cicatrization is over by the third month after surgery. 17 operations with classical clinoid resection and 17 ones with that and tangent clinoid autoclinoplasty were carried out in patients with corneal astigmatism of 2.0 to 6.25 diopters, the follow-up periods being from 6 months to 4 years. The mean reduction of astigmatism after the use of the aforesaid methods has made up 2.47 and 4.8 diopters respectively (according to the data of subjective examination of refraction).
