Description
Xinyue Yang and four co-authors compare two artificial lens designs for cataract patients with strong nearsightedness in a 2024 study. Ninety three patients received either a zonal refractive multifocal lens or a diffractive bifocal lens, and vision was checked three months after surgery. Measures covered sharpness at three distances, focus curves, optical aberrations, and patient questionnaires.
The bifocal group saw better up close, while the multifocal group did better at arm's length. The bifocal lens scored better on an optical quality measure but worse on reported glare, halos, and starbursts. Satisfaction and freedom from glasses ran higher in the bifocal group. Both lenses restored distance vision well, so the choice hinges on near versus middle priorities and tolerance for light effects.
