What is cataract surgery?
During a cataract surgery, the cloudy lens is removed from the eye and replaced with a clear lens. Ophthalmologist and Sharecare Advisory Board member David Demartini, MD explains in this video.
We have lenses now that can correct astigmatism. They can correct for nearsightedness
or farsightedness. And they also can be multifocal. [UPBEAT MUSIC]
Cataract surgery is a surgery where a cloudy lens is removed from inside the eye and a clear implant lens
is placed in its place inside. So when this lens inside gets cloudy,
we have the ability to numb up the eye, go in, and remove the cloudy lens
and replace it with a very sharp, clear implant lens. We have the ability to measure the distance and the power
of the cornea and we have wonderful ultrasound and optical coherence programs that
allow us to predict what the power of that lens should be that we replace it with. We have lenses now that can correct astigmatism.
They can correct for nearsightedness or farsightedness. And they also can be multifocal so
that one can be corrected both for distance and for reading. [AUDIO LOGO]
