Comparing Refractive Prediction Accuracy of IOL Master 700 and Sirius Utilizing the Barrett Universal II Formula

Under the Barrett Universal II formula, IOLMaster 700 yields more accurate refractive predictions than Sirius, with smaller systematic drift and absolute error, irrespective of axial length. Thus, IOLMaster 700 with Barrett Universal II is the preferred biometry for superior refractive accuracy. This study offers surgeons practical guidance for improving post-operative visual outcomes and patient satisfaction.
