RED is NO! – GREEN is GO! Successfully fitting EDOF lenses for presbyopia - Positive Impact

This session is now fully booked

About the session

For some 30-years practitioners have been told to ‘push the plus’ when fitting conventional zonal multifocals. Successfully fitting newer EDOF designs requires a different approach that isn’t immediately intuitive – in fact it is initially quite alien. Understanding the differences in how multifocal designs using EDOF optics work, will help practitioners begin to rethink their approach. 

Continuing to fit non-zonal multifocals by simply applying the same ingrained zonal lens fitting approach, with complete disregard for the new technology’s well-researched fitting guide, is a recipe for unnecessary chair-time and possible failure. This workshop will discuss the EDOF optics of today’s multifocal designs and then demonstrate how to successfully fit a design using patented catenary optics.
