4. We don't have three eyes
Monovision worked well for many patients who had discrete distance and near demands, but it stumbles now that intermediate vision is so important.
Intermediate demands are now critical across all age groups. For example, Pew Research Center data shows almost 60 percent of the elderly use the Internet.14 Grandma doesn’t sit around knitting and waiting for a letter from the grandkids—she stalks them on social media.
The ability to provide clear distance, intermediate, and near vision with smooth transitions among working distances is a very real challenge.
Bausch + Lomb used virtual models to develop its 3-Zone Progressive Design for its Ultra for Presbyopia and BioTrue for Presbyopia lenses. Rather than power steadily changing from near to distance, the design incorporates areas of consistent power at distance, intermediate, and near with seamless transitions between zones. The result is a high consistency of power than can provide better vision at multiple distances.
5. Satisfy patients
Increased patient satisfaction retains more than fitting fees and materials fees—it retains patients.
Some 76 percent of patients preferred multifocals to monovision.15 Presbyopes want and need more from their eyecare providers and their contact lenses, but we are busier and inundated with product options and new fit guides.
However, the process is also easier than before. When surveyed about fitting 3-Zone Progressive Design multifocals, 92 percent of eyecare providers said they are easy to fit, and 96 percent of patients were successfully fit by the second visit.16
Optometrists must break the habit of adding plus over the nondominant eye and instead start the patient in a multifocal when she is an emerging presbyope, not when she needs high adds. Why start an early presbyope down a road we cannot sustain? Use those low add lenses. Set yourself and your patients up for future success.
