SRK Formula History

Essentials in Ophthalmology
Abstract This is a complete history of the formulation and development of the SRK family of formulas by Drs. Sanders, Retzlaff, and Kraff from the original SRK I in 1980 to the final SRK/T in 1990 including all the travails that led to their development.

Theoretical versus SRK I and SRK II calculation of intraocular lens power

Journal of Cataract and Refractive Surgery, 1990
The predictability of a theoretical, computerized (PC-assisted) intraocular lens (IOL) power calculation method and of the Sanders-Retzlaff-Kraff [SRK] I and II methods was evaluated from preoperative and postoperative biometry in 202 cataractous patients who had extracapsular cataract extraction (ECCE).

[Prevention and therapy with immunoglobulin SRK].

Helvetica chirurgica acta, 1979
In a clinical study the tolerance and efficacy of a gamma-globulin, treated at pH 4, has been studied. This preparation manufactured by the "Zentrallaboratorium des Blutspendedienstes SRK" can be given intravenously without any risk of untoward reactions. It has been applied in high dosages up to 99 g per week.

Clinical evaluation of the Holladay and SRK II formulas

Journal of Cataract and Refractive Surgery, 1990
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.

[Reliability of the SRK formula].

Ceskoslovenska oftalmologie, 1991
The authors investigate the postoperative dioptric deviation from the calculated dioptric power of emetropic intraocular lenses by means of the SRK formula. The deviation varied in 82% of the operated eyes within the range of +/- 1.5 D. More accurate calculations were achieved in a group of eyes with a normal axial length of the eyeball (22.0 to 24.5 ...

Parameters for the PR and SRK equations of state

Fluid Phase Equilibria, 1992
Abstract Bian, B.G., Wang, Y.R., Shi, J., 1992. Parameters for the PR and SRK equations of state. Fluid Phase Equilibria, 78: 331-334. The critical compressibility factor zc calculated from cubic EOS is sensitive to parameter truncation. Different truncated parameters and corresponding zc are given for PR and SRK EOS.

SRK and PR alpha functions for ice

Fluid Phase Equilibria, 2013
Abstract In order to avoid possible phase inconsistencies in water saturation point calculations, this paper proposes to treat ice as a regular component. For SRK and PR cubic equations of state, the goal of this paper is to provide the parameters of an alpha function able to very accurately reproduce the vapor pressure over ice between 173 K and 273.

SRK-EOS calculation for crude oils

Fluid Phase Equilibria, 1983
Abstract Analytical data for North Sea oils and gas condensates have been measured. The data include GC and TBP analyses and measurements of molecular weights, specific gravities, and PNA-distributions of most TBP-fractions. For each mixture, a few dew and bubble points have been measured, and in addition PVT-data and separator flash compositions ...

Density improvement of the SRK equation of state

Fluid Phase Equilibria, 1997
The SRK equation of state has been modified by volume translation in order to improve its accuracy both in- and outside the critical region. A temperature dependent volume correction is proposed which can match the true critical point of the pure component, and provides accurate densities for polar and non-polar pure substances both near to and far ...
