title: [Calculation for emmetropic intraocular lenses in hypermetropia].
abstract: Authors evaluated postoperative refractive errors after implantation of intraocular lens at the set of 429 eyes. There predominated eyes with short axial length (AL) at this set: 304 eyes had AL < 22 mm, average AL was 21.54 mm. The basic point was to correct the linearity of SRK formula by different way from SRK II formula, while keeping the new formula simple to use. Authors reached following modification of A-constant in SRK formula: new A-constant = original A-constant + C, where C = 0,146*AL2 - 7,702*AL + 100,130.
