Aim: To compare IOL power & axial length estimated by optical biometry (OB) and ultrasonicbiometry (UB). Material & methods: A prospective & comparative study was planned to compareaxial length & IOL power calculated by Appa Scan AME - 01A (Appasamy Associates, India) (UB) &IOL master 500 (Carl Zeiss Meditec, Jena, Germany) (OB). Autokeratometry evaluated using IOLmaster 500 & SRK/T formula were taken for IOL power estimation. Spss software version 20.0 wasused for analysis. Results: Overall agreement between UB & OB for axial length & IOL power wasexcellent ( weighted kappa 0.807 & 0.825 respectively). Conclusion: Ultrasound biometry, a cost-effective method for IOL power & axial length calculation, still holds value as compared to opticalbiometry for routine cataract surgeries.
