CooperVision BIOFINITY User guide

  • Hello! I am a chat assistant that has reviewed the Biofinity multifocal lens fitting guidelines. This document provides detailed steps for fitting multifocal contact lenses, including initial visit procedures, lens design selection based on ADD power, and follow-up visit guidance. I'm ready to answer your questions about the fitting process, lens specifications, and other aspects mentioned in the document.
  • What is the initial step in fitting Biofinity multifocal lenses?
    How are D and N lens designs chosen?
    How long should patients adapt before assessing vision?
A simplified fitting
philosophy
Our new fitting process is based
on eye care professionals’ real-world
experiences.
