Abstract |
The paper discusses the results of 28 laser operations carried out by bitoric nomograms and 18 operations carried out by monotoric nomograms for correction of high astigmatism (3 and more diopters) by laser in situ keratomileusis ( LASIK). The patients' ages varied from 21 to 38 years. Eximer photokeratectomy was carried on a EC 5000 Nidek laser, lamellar section of the cornea was made with a Hansatome microkeratome. Bitoric keratoablation was carried out by an original method. Clinical refraction, visual acuity, and incidence of reoparations were evaluated in both groups 6 months postoperation. Differences in refraction and visual acuity were negligible. The incidence of reoparations in bitoric keratoablation was 25%, in monotic one 44%. Visual acuity with correction was higher after bitoric keratoablation of astigmatism. Hence, bitoric keratoablation is preferable for correction of high astigmatism by LASIK.
