Despite reported successes with progressive addition lenses, lined multifocals remain the lens of choice for previous lined multifocal wearers.
To explore the feasibility of switching lined multifocal wearers to PALs, in a prospective clinical trial we interviewed 265 lined multifocal wearers, prescribed a new PAL (Varilux Comfort) and then interviewed them again to compare the lens types and patient preferences.
PALs ranked significantly higher than lined multifocals for all questions and were preferred by 92 percent of the patients.
PALs should be the lens of choice for previous bifocal wearers.
