SUBSTANCE: the present innovation deals with forming a corneal fragment without its lifting, performing cataractous extraction along with IOL implantation, lifting the cover of corneal fragment in a month, not earlier, affecting with ultraviolet radiation onto stromal bottom and putting corneal fragment to its former place. Moreover, fragment's stem should be oriented by weak meridian, and cataractous extraction through corneal tunnel incision and IOL implantation should be carried out 1-7 d later. Moreover, incision should be placed in projection of weak astigmatism axis being 1 mm against the limbus parallel to it. To obtain complicated myopic astigmatism at detecting IOL optic power one should detect corneal refraction by special mathematical formula depending upon physical refraction of weak meridian, the value of hypermetropic shift of refraction's spherical component for 1.0 D of negative cylindrical ablation, and astigmatism degree. The obtained complicated myopic astigmatism should be corrected due to negative cylindrical ablation of stromal bottom. The present innovation enables to obtain maximally high acuity in patients without any additional spectacle correction.
