●
A web platform, built as an Angular application with a cloud infrastructure on Amazon Web Services
●
The platform consists of three components: for optimizing formula constants, performing IOL power calculations and predicting refractive error
●
The platform allows eye care professionals from around the world to easily perform preoperative lens power calculations using the five formulas based on input data: lens types, actual eye measurements, the target refraction and eye status that can be “untreated eye” or “previous laser eyes”
●
Users can use default formula constants, or optimize constants clinical historical data for the four classic formulas depending on eye status and train the ML model for the client’s formula
●
Optimized constants are updated to the latest data upload and can be downloaded to an excel spreadsheet
●
The calculation results, i.e. the desired lens power, can be downloaded as a PDF file
●
A predictive algorithm delivers an easy-to-interpret and concise histogram of postoperative refraction results relative to the target refraction for different formulas to easily compare accuracy between them; a filter option is available to extract proper results, enabling users to select the lens type, eye axial length range, eye status (untreated or previous surgery), postoperative stage and corneal astigmatism range
