Abstract :
Purpose: To compare the refractive outcomes after phacoemulsification with an Intra ocular lens (IOL) using IOL master 700 optical biometer versus conventional ultrasonographic biometer.
Materials and Methods: A retrospective analysis of patients who underwent phacoemulsification with intra ocular lens implantation between April 2019 and March 2020 was done. Data of 654 eyes (607 patients) was shortlisted and analyzed. IOL power calculation was done with applanation ultrasonographic biometer and IOL Master 700 optical biometer by dividing patients into 2 groups. SRK/T formula was used in both cases for IOL power calculation. Refractive outcomes were determined at least four weeks after the surgery and the results were recorded. Data analysis was done using Microsoft Excel 2017 and SPSS software.
Results: In group A, applanation ultrasonographic biometer was used, 66.9% of patients were having post operative refractive power between ±0 to ±0.75D and in group B IOL Master 700 was done 89.8% of patients, were having post operative refractive power between ±0 to ±0.75D. Thus, refractive outcome was better in Group B eyes (89.80%) as compared to group A eyes (66.90%) and this difference was statistically significant (p value
