Abstract

Reviews the results of correction of complex myopic astigmatism with asymmetric form of disposition on the cornea by two methods, with centered and decentered photokeratoablation. Analyzes the results of 80 laser keratomileusis operations for medium and high myopia. Describes a method of calculations and keratotopographic detection of asymmetric astigmatism and a method for transferring it into symmetrical form in computer-aided keratotopography. Two types of interventions brought about a good refraction result (sphere equivalent -0.66 +/- 0.54 diopters) and high resolving capacity of the eye (0.88-0.99). Decentered keratoablation led to a significant increase in visual acuity without correction, this indicating a better adequacy of this method, discussed in this paper.
