Multifocal Lenses Don’t Boost Satisfaction
With Cataract Surgery
People who have multifocal lenses implanted after cataract surgery
are less likely to need reading glasses afterwards than those
who receive monofocal lenses, but they aren’t any happier
about their quality of vision. The reason is that people who
get multifocal lenses appear to have unrealistic expectations
about the device, according to a new study.
Dutch researchers randomized 75 people who needed cataract surgery
to receive either monofocal or multifocal lenses. Patients were
counseled about what to expect from each of the implants.
Three months after both eyes had been operated on, about 90%
of the patients in both groups were satisfied with their quality
of near and far vision when using glasses. Although more people
in the multifocal group were able to see well without reading
glasses most of the time (43% vs. 22%), they were no more likely
than those in the monofocal group to state that their expectations
of surgery were met (62% vs. 63%).
The researchers conclude that although multifocal lenses can
reduce people’s dependence on reading glasses, more than
half of people who receive them still need glasses—and
that patients should be aware of this before surgery.
