Thecornea is the clear, protective outer layer of the eye. Along with the sclera
which is the white of the eye, it serves as a barrier against dirt, germs, and
other particles that can harm the eye's delicate components. The cornea is also
capable of filtering out some amounts of the sun's ultraviolet light. The
cornea also plays a key role in vision. As light enters the eye, it is
refracted, or bent, by the outside shape of the cornea. The curvature of this
outer layer helps determine how well your eye can focus on objects close-up and
far away. There are three main layers of the cornea. Epithelium is the most
superficial layer of the cornea, the epithelium stops outside matter from
entering the eye. This layer of the cornea also absorbs oxygen and nutrients
from tears. The Stroma is the second layer and the largest layer of the cornea
and is found behind the epithelium. It is made up mostly of water and proteins
that give it an elastic but solid form. The Endothelium is third layer and a
single layer of cells located between the stroma and the aqueous humor - the
clear fluid found in the front and rear chambers of the eye. The endothelium
works as a pump, expelling excess water as it is absorbed into the stroma.
Without this specialized function, the stroma could become water logged, hazy
and opaque in appearance, also reducing vision.

The cornea is the tissue on the very front of the eye. It is clear and covers
the iris and pupil. It works with the lens to provide focusing power to the
eye. If the cornea becomes opaque, swollen, or scarred, vision is compromised..

What are the most common benefits of
this surgery ?
The transplanted tissue will enable
the patient to regain much of the eyesight lost by the condition which damaged
the patient's own cornea. The surgery can also eliminate symptoms due to the
corneal condition. Because this procedure is performed only after medicines and
other treatments have failed, it is the final method of providing relatively
normal eyesight to someone having serious vision problems due to damage to
their cornea.
What
will happen at the initial consultation ?
Once your ophthalmologist have
determined you need a corneal transplant he or she will perform a full physical
to determine whether you have any conditions or are taking any medications that
might affect the surgery. He or she will then arrange for you to be put on the
list of persons waiting for corneal transplant tissue. At We Care India partner
Eye Hospital, your connea transplant will be done immediately, with no wait
list.
How
is the procedure performed?
The transplant procedure involves
removing the diseased or damaged tissue, then replacing it with the donor
tissue. The entire operation is done under a surgical microscope. After taking
measurements of the amount of tissue to be removed, the diseased corneal is cut
and lifted away from the eye with a special round tool that works much like a
cookie cutter called a trephine. Once the damaged tissue is removed, the donor
cornea is cut to a matching size and placed on the patient's eye. It is held in
place with very fine stitches using suture material that is about as thin as a
hair.
