many, clear vision is not possible without spectacle
correction, and proper eyewear is important to enjoy vision to
its fullest. While glasses or contacts can help render clear
vision, sometimes your eye exam will reveal other conditions
that can impact eyesight.
or opacity of the lens inside the eye, can keep properly
focused light from fully reaching the retina," says Mayo
Clinic Health System ophthalmologist Dr. Ronald Hessler.
"Occasionally occurring in children or younger adults for
genetic or medication reasons, this lens opacification affects
most of us to some degree in later life."
cataracts affect more than 22 million Americans. Fortunately,
cataract removal surgery can restore vision by removing the
hazy lens and replacing it with a clear intraocular lens (IOL)
implants are prescription lenses that are specifically chosen
for your eye’s degree of nearsightedness or farsightedness,
often reducing your need for glasses to see in the distance
and, for some, resulting in only the need for inexpensive
reading glasses. Also, IOL implant technology has advanced to
allow premium lenses to neutralize astigmatism, which is
irregular focusing of light into the eye, and even multifocal
IOL implants to yield clear vision at distance and for reading
question I’ve often been asked is: ‘Can cataract surgery
be done with laser?’ Until recently, the answer was
no," says Hessler. "Laser refractive surgery, known
by names such as Lasik (laser-assisted in-situ keratomileusis)
and PRK (photorefractive keratectomy), has been popular in
recent years. This technology reshapes the cornea — the
clear domed windshield on the surface of the eye — to better
focus light through the lens inside the eye and onto the
retina, eliminating or reducing the need for glasses."
viable solution for many, this treatment will not correct an
eye with cataract, since the focused light still passes
through the hazy cataract lens inside the eye. Your cataract
surgeon must enter the eye through the cornea to access, then
fragment and remove the cataract using ultrasound energy
before placing the IOL implant.
cataract surgery allows the incisions to be tiny (only
slightly larger than the diameter of a toothpick), resulting
in speedy recovery and discharge home after the procedure
lasting only about 20 minutes.
now, the surgeon has had to create the corneal and lens access
incisions manually using blades and instruments. While a
practiced surgeon can accomplish this with great skill, new
laser technology enables even greater precision in creating
the incisions required in cataract surgery.
laser treatment, called femtosecond laser surgery, is
performed at the beginning of the procedure, is painless and
only lasts about 30 seconds. It enables more efficient
cataract removal, requiring less energy and less stress to the
eye. It also results in faster recovery and getting you back
to enjoying life with the best eyesight possible.
new glasses alone aren’t enough to correct your vision, ask
your eye care provider if you have cataracts and if you are a
good candidate for femtosecond laser surgery," says
