Improvement in biometry and formulas have raised the bar for accurate IOL power calculation. However, when we look closely at the performance of a specific IOL model, we often find that the prediction error varies with the implant power. This phenomenon has no explanation other than the optic design of the IOL has shifted over the power range, thereby disrupting the assumptions of the calculations. By this report we call the industry to be more transparent and disclose the basic information about the IOL design that is important for accurate IOL power calculation...
