Accuracy of Intraocular Lens Power Calculation Formulas Using Total Keratometry in Eyes With Previous Radial Keratotomy

Key Points

• This research aims to evaluate the accuracy of intraocular lens power calculation formulas in eyes that have undergone radial keratotomy.
• Evaluated prediction accuracy of different intraocular lens power calculation formulas.
• Analyzed eyes with prior radial keratotomy to assess formula performance.
• Focused on the use of total keratometry for enhanced predictions.
• The LISA-MRS formula showed the highest prediction accuracy for intraocular lens power in post-RK eyes.
• Total keratometry improved the accuracy of the Holladay 2 and LISA-MRS formulas.
