The
human eye can be compared to a camera. When the shutter (cornea) is
open, light enters and passes through a lens which transmits the image
to the film (retina). When the lens is clouded by fog (cataract), it
cannot focus properly. The lens is completely replaced by an implant
during no-stitch cataract surgery.
We do
not know exactly what causes most cataracts, but we do know that
cataracts are a normal part of aging. Many people over 65 show signs
of cataract, however, not all cataracts compromise vision.
Most
people have some clouding of their eye's natural crystalline lens
after the age of 60. This clouding is more commonly referred to as a
cataract. About 50% of Americans in the age group of 65-74 have at
least one cataract, and about 70% of those age 75 and over have
cataracts. Simply stated, when the eye's lens becomes cloudy, light
cannot be properly focused on the retina; thus, visual acuity
decreases.
The
only "cure" for poor vision due to cataract is removal of
the eye's lens and implantation of a new, man-made focusing device
called an intraocular lens (IOL).
Many people with cataracts may
experience symptoms such as:
-
Cloudy,
fuzzy, foggy vision
-
Difficulty
in seeing to drive, especially at night
-
Trouble
seeing to do close work
-
Problems
seeing television
-
Colors
that seem dull, faded, not as bright
-
Frequent
changes and a stronger glasses prescription
-
Haloes
around lights
-
Bothersome
glare
-
A
milky white spot or cloudy spot visually apparent in the center of
the eye
After
cataract surgery, the extracted lens is replaced by an intraocular
lens to restore clear vision. We specialize in the new, revolutionary multi-focal lens implants for cataract surgery, that provide full range of vision - near, distance and intermediate, resulting in greater independence from glasses or contact lenses. We perform no-stitch small incision cataract surgery in our own ambulatory surgical center in Manhattan.
