Clinical evaluation of the Holladay and SRK II formulas

Abstract

We compared the accuracy of the Holladay and SRK II intraocular lens power calculation formulas with that of two commonly used formulas, the Binkhorst and SRK. We found no significant difference between the accuracy of the four formulas in cases of posterior chamber lens implantation. For anterior chamber lenses, the SRK II formula was significantly less accurate than the other three formulas in eyes with long axial length.
