IOL Calculator for Eyes with Prior RK

Data submitted in the below form will not be saved and should be printed if the user wishes to reference that data at a later date. The current version of the Prior Myopic LASIK/PRK is still in development and is meant for testing purposes only. The ASCRS team and its partners are still implementing formulas, while making small adjustments to the forms functionality for ease of use.

There are several fields required, while other fields are optional. Please note the help notifications (blue) and error notifications (red) while you are entering in your values. These will help guide you to inputting acceptable values by the current formulas. Once you’ve entered all of your data, press the “Calculate” button (orange) at the bottom of the page and your IOL Power outputs will display at the bottom of the page. This may take a few seconds, so please give it time. You will receive outputs for all formulas whose input criteria are met.
