Latest CME Webinar: A Challenging Day in the OR: Tough Choices in IOL Selection

Moderators and faculty have assembled several challenging OR cases covering topics on IOL selection. Faculty will engage with moderators and attendees to work through case planning prior to surgery. Topics to be discussed include which power, which optic design, how to select the best IOL option and IOL calculations. 

Credits: By completing this activity you will earn 1.25 AMA PRA Category 1 Credits™.
Activity Expiration Date: September 30, 2024

IOL Calculators

Barrett Toric Calculator

This calculator is intended to be used in conjunction with a comprehensive ophthalmic examination and the appropriate diagnostic tests and measurements necessary for cataract surgery candidates being considered for a Toric intraocular lens. 

Hill-RBF Calculator

The Hill-RBF Calculator is an advanced, self-validating method for IOL power selection employing pattern recognition and sophisticated data interpolation. It has been optimized for use with the Haag-Streit LENSTAR, using optical biometry for all axial measurements and high density autokeratometry.

Post-Refractive IOL Calculator

This calculator facilitates  IOL power calculation in eyes that have undergone LASIK/PRK/RK. The IOL Calculator is meant to serve as an adjunct tool to assist physicians in selecting the appropriate IOL for a particular patient.
