 NearVision
CK (Conductive Keratoplasty) is a non-laser procedure developed specifically
for baby boomers who have had clear vision all their life, but now
struggle to see life's details with reading glasses.
NearVision CK is a safe, minimally invasive procedure that involves
no cutting of your cornea. And it's performed using the ViewPoint®
CK System, the only FDA-approved technology for the temporary improvement
of near vision. This makes it an ideal procedure for people over 40,
for whom safety is often the most important factor in their decision
to undergo a vision correction procedure.
This section provides information about how NearVision CK works, who
is a candidate for the procedure, and much more. |

The eye has been called the most complex organ
in our body. It's amazing that something so small can have so many
working parts. But when you consider how difficult the task of providing
vision really is, perhaps it's no wonder after all.
The eye is like a camera. It lets light in through the cornea, which
is like a camera's aperture. The amount of light allowed in is controlled
by the pupil, which opens and closes a bit like a shutter. The light
focuses on the retina, which sends the image to the brain, acting
as film would in order to record the light. |

Lens
Located behind the pupil, the lens is the secondary mechanism
of focus after the cornea, adjusting the amount of refraction
required within the eye to focus an object on the retina. |
| • |
Cornea
This is the window of the eye where the majority of focus takes
place. |
| • |
Pupil
This is the black spot in the center of the eye where light
enters. Pupil size changes when the iris tenses or relaxes depending
on the amount of light present. |
| • |
Iris
Actually classified as a muscle, the iris is the colored portion
of the eye that adjusts the amount of light allowed to enter
into the pupil. |
| • |
Conjunctiva
This is the transparent covering of the eye that lies between
the eyelid and the front of the eye. |
| • |
Retina
The retina is the nerve center of the eye where light is converted
into an electrical signal that travels to the brain. Cells,
called rods and cones, within the retina transmit these signals
along the optic nerve, consequently enabling sight. |
| • |
Optic Nerve
This is the pathway between the eye and the brain along which
the signals produced by the rods and cones travel to the brain. |

| What Happens to the Eye When We Age? |
| |
| Changes in vision occur as we age. One of
the more common Conditions Associated with aging is presbyopia. This
condition occurs when the lens becomes less flexible and therefore
loses its ability to focus by thickening or thinning itself. The result
is blurred vision when trying to focus on close-up objects. |
