Impact of Corneal Posterior-to-Anterior Radius Ratio on Intraocular Lens Power Calculations: Rethinking the Role of Total Keratometry
By MedXY|Aug 20, 2026
This study reveals that the corneal posterior-to-anterior radius ratio (PAR) influences the refractive prediction differences between standard keratometry (K) and total keratometry (TK) for intraocular lens (IOL) power calculations, undersc
