JF - Tropical Journal of Ophthalmology and Otolaryngology JA - Trop j ophthalmol otolaryngol VL - 6 IS - 1 SE - Original Article DO - 10.17511/jooo.2021.i01.03 UR - https://opthalmology.medresearch.in/index.php/jooo/article/view/179 AB - Aim: To compare IOL power & axial length estimated by optical biometry (OB) and ultrasonic biometry (UB).Material & methods: A prospective & comparative study was planned to compare axial 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 IOL master 500 & SRK/T formula were taken for IOL power estimation. Spss software version 20.0 was used for analysis.Results: Overall agreement between UB & OB for axial length & IOL power was excellent ( 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 optical biometry for routine cataract surgeries.
