Influence of the Corneal Posterior-to-Anterior Radius Ratio on IOL Power Prediction Using Standard and Total Keratometry.
PURPOSE To compare the predictive accuracy of standard keratometry (K) and total keratometry (TK) for intraocular lens (IOL) power calculation across eyes stratified by the posterior-to-anterior corneal radius ratio (PAR). DESIGN Retrospective evaluation of IOL power calculation accuracy. METHODS A total of 1,314 e...
