Thanks to a new wearable visual simulator, patients and surgeons are able to see the effects of an intraocular multifocal lens -- which allows seeing at different distances -- in a realistic way ...

To evaluate the effect of mild posterior capsule opacity (PCO) on visual acuity (VA) in eyes implanted with a diffractive multifocal intraocular lens (IOL) compared with a monofocal IOL, and the ...

Breakthrough technology lets patients "try on" intraocular lens options in immersive 3D environments before surgery Cataract surgery is among the most frequently performed and life-changing procedures ...

Multifocal lenses use multiple refractive zones built in rings to give patients distance and near vision. These lenses are designed to address the problem of presbyopia, in which people over the age ...

After bilateral cataract surgery, patients implanted with multifocal intraocular lenses (IOLs) were more likely to be spectacle-independent but also to undergo IOL exchange than those with monofocal ...

Monofocal and multifocal lenses are both types of artificial intraocular lens (IOL). A monofocal lens has one focusing distance, whereas a multifocal lens can focus on close and far distances at the ...

Cataract surgery is a once-in-a-lifetime investment in your eyes that can improve your quality of life for the long term. Advanced lens options can reduce or eliminate the need for glasses after your ...

Corneal refractive surgery has been performed on millions of patients to decrease their spectacle dependence. Most of these patients have high expectations of visual function—but as these patients age ...
