I’m just going by what Consumer Reports said in an article earlier this year. The study that it was based on is dated, so perhaps their advice is dated too. Here is a quote:
" Be wary of premium lenses. In standard cataract surgery, doctors remove the clouded lens and replace it with an artificial monofocal lens, which provides clear images at either near or far vision. There are multifocal lenses that do both, so you don’t also have to wear glasses.
But multifocal lenses cost up to $4,000—and usually aren’t covered by insurance. More worrisome, a 2012 review found that while the lenses provided better near vision, they also produced more complaints of halos and glare. Other research shows that people with multifocal lenses are also more likely to need repeat surgery.
One time you might consider a premium intraocular lens: if you have an astigmatism, or an irregularly shaped cornea.
Special lenses, called toric lenses, can correct that problem, says David Sholiton, M.D., an ophthalmologist at the Cleveland Clinic. And studies reveal that most people who get them are satisfied. But you will probably have to pay $1,000 or more out of your own pocket because insurance rarely covers them."
I suspect this is the review they are talking about. This seems to be the conclusion:
“The multifocal lenses had drawbacks: people with these lenses were more likely to see halos around lights and had reduced contrast sensitivity (the ability to distinguish an object against a background which is similar to the object itself). Multifocal lens implants reduce spectacle dependence after cataract surgery but at the expense of clarity. Ultimately it will be up to the individual to decide which type of lens they would prefer.”
