摘要：
FIELD: medicine.SUBSTANCE: invention refers to ophthalmosurgery and can be used for the intraoperative correction of a corneal shape in cataract extraction. Following the shape of the cornea, which appears to have a correct spherical shape, requires performing two limbal paracentheses of the width having no influence on the corneal spherical shape, but no more than 1.5mm, before the cataract extraction the paracentheses are arranged in any surgically comfortable corneal meridians, while the tunnel self-sealing incision is performed for an injector implantation of an elastic intraocular lens of the width also having no influence on a corneal curvature, but no more than 2.0mm and localised in any implantable upper portion of the limb. Shaping the spherical cornea, which is non-spherical with a strong meridian in the surgically comfortable region is ensured by performing two limbal paracentheses of the width no more than 1.5mm before the cataract extraction the paracentheses are arranged diametrically in the corneal strong meridian the injector or pincer implantation of the elastic intraocular lens is ensured by performing a tunnel self-sealing incision within the paracenthesis in the upper part of the limb of the width desired to recover the spherical shape, but no more than 6.0mm, and if the strong meridian is found in the surgically uncomfortable region, shaping the spherical cornea is ensured by performing two limbal paracentheses of the width of no more than 1.5mm to be arranged in any surgically comfortable corneal meridians, while the injector or pincer implantation of the elastic intraocular lens is ensured by performing a tunnel self-sealing incision within the strong meridian in the upper part of the limb of the width desired to recover the spherical shape, but no more than 6.0mm. In all cases, the aspherical lenses are implanted, while their dioptric value is calculated in accordance with a degree of a weak meridian deflection if observing a small difference
