title: A new intraocular lens formula for high myopia.
abstract: We developed a formula suitable for calculating intraocular lens power for eyes with axial lengths of 27 mm or greater. We then used this formula in a prospective study to determine its reliability in 32 eyes. In these latter cases the mean error between predictive postoperative refraction and actual postoperative refraction was 0.36 D, with 67% of the cases having less than 1.0 D error; 84% of the cases having less than a 2.0 D error; and no cases having an error greater than 3.0 D. The new formula provided greater accuracy for these highly myopic eyes than the SRK, SRKII, Hollady, and Thompson formulas.
