Prediction error and accuracy of intraocular lens power calculation in pediatric patient comparing SRK II and Pediatric IOL Calculator
BACKGROUND Despite growing number of intraocular lens power calculation formulas, there is no evidence that these formulas have good predictive accuracy in pediatric, whose eyes are still undergoing rapid growth and refractive changes. This study is intended to compare the prediction error and the accuracy of predictability of intraocular lens power calculation in pediatric patients at 3 month ...
متن کاملSRK II formula in the calculation of intraocular lens power.
We studied 400 eyes which underwent cataract extraction with posterior chamber intraocular lens (IOL) implantation to compare the predictive accuracy of various IOL power calculation formulae. The new Sanders-Retzlaff-Kraff (SRK) II formula was more accurate than the original SRK and Binkhorst II formulae. Modification of the A constants used in the SRK II formula to make it 'surgeon specific' ...
متن کاملAccuracy of intraocular lens power calculation in paediatric cataract surgery.
AIMS To determine the accuracy of intraocular lens (IOL) power calculation in a group of pseudophakic children. METHODS A retrospective analysis of biometric and refractive data was performed on 52 eyes of 40 infants and children, who successfully underwent cataract extraction and IOL implantation. The following parameters were included: age at the time of surgery, keratometry, axial length, ...
متن کاملComparison of intraocular lens power calculation using the Binkhorst and SRK formulae: a clinical study.
Comparison of results of intraocular lens implants with IOL powers obtained by Binkhorst and SRK Linear Regression formulae was done using various models and brands of intraocular lenses. Of 887 pseudophakic patients. 415 patients received IOL's with their powers calculated for planned emmetropia, by means of theoretic formula devised by R.D. Binkhorst and in the remaining 472 eyes the IOL powe...
متن کاملSources of error in intraocular lens power calculation.
PURPOSE To identify and quantify sources of error in the refractive outcome of cataract surgery. SETTING AMO Groningen BV, Groningen, The Netherlands. METHODS Means and standard deviations (SDs) of parameters that influence refractive outcomes were taken or derived from the published literature to the extent available. To evaluate their influence on refraction, thick-lens ray tracing that a...
