The document summarizes information about cornea transplants, including: 1) A cornea transplant involves replacing damaged corneal tissue with tissue from a deceased donor. 2) The procedure has a short recovery time and high success rate compared to other transplants, but risks include rejection and infection. 3) Issues around cornea transplants include lack of donors causing organ trafficking, high financial costs limiting access, and ethical concerns around related crimes.

Organ transplant
Introduction :
My essay will be about organ transplant. Many kinds of organ transplant exist. But my
topic of writing is cornea transplant. And then the benefits and limitations and also the
one-world issues of this topic ( social, ethical and political ).
Let’s give some functions of cornea. It helps to shied the rest of the eye from germs, dust,
and other harmful matter. The cornea acts as the eye’s outermost lens. It functions like a
window that controls and focuses the entry of light into the eye. The cornea also serves as
a filter, screening out some of the mist damaging ultraviolet wavelengths in sunlight.
Without this protection, the lens and the retina would be highly susceptible to injury from
ultraviolet radiation.
Background Information :
A cornea transplant is a surgical procedure to replace part of your cornea with corneal
tissue from a deceased donor. The method of cornea surgery is a little bit complex.
Sometimes, the body rejects the transplanted tissue. This occurs in a small number of
patients. Other dangers for a corneal transplant are bleeding, infection of the eye,
Glaucoma ( high pressure in the eye that can cause vision loss ) and swelling of the front of
the eye. The operation can be carried out either under local or general anaesthetic, and
then involves the removal of a circular piece of the affected cornea and replacing it with a
piece of the donor cornea of exactly the same size and shape. Then, it is sewn into place
with very fine stitches. However the operation can be more complex and can take one
hour. Also your eye is never removed and replaced during an operation. Clearly, the
recovery time is quick.

2. Body :
Benefits and limitations
There are many benefits of cornea transplant. Moreover, the cornea transplant has more
benefits than the other transplants.
First, the recovery time of corneal transplant is faster that other transplants. Ordinarily, if
we got the transplant, we can leave the hospital in a day. However almost all the other
surgeries and other transplant, requires us to be hospitalized. Also the success probability
of cornea transplant is higher than other surgeries. Second, before getting the transplant,
although the problem with our vision is very serious, we can still recover our perfect vision
again. Lastly the operation time is pretty short and the probability of having side effects is
few. Many patients after the operation have some problems caused by side effects, and
also a few patients had problems because of long procedure. Sometimes, the long time
can inflict the patients with pain. When you think of this, you can know that cornea
transplant relatively has a lot of benefits.
Although the transplant has many benefits, also it has some limitations. First, Complications
after the operation are possible. Of course the probability is low. Such complications may
include eye infection, clouding of the eye, an increase in pressure, rejection of the donor
eye and the swelling of the cornea. In some cases, there may be an immune response
where the donor’s body rejects the eye transplant. And then sometimes we cannot find a
cornea to be used in the transplant, because the donors are not available. Second, it can
cause organ ( cornea ) trafficking. For example, if someone need cornea to transplant, but
cornea donor is lack. So he cannot get cornea transplant. In such a situation, he can
smuggle the cornea to get transplant, it means organ trafficking. It can be a big issue in
out society. Also it can cause serious prime.

One World Issues:
Social Issues:
Many organ transplants can affect the social issue. Nowadays organ donors are becoming
unique. It means to find suitable organ become more difficult than before. This situation can
cause organ trafficking, and a lot of religious groups oppose the trafficking. The arguments
like this, are able to be a big issue or problem in our society.
Ethical issues:
Organ transplant relate with ethical issue. As I have mentioned before, it can cause organ
trafficking. And then the organ trafficking also cause some crimes. The crimes are cruel. For
example, oneday a Korean couple visited China to travel, however the woman was
kidnapped and after few days, the woman was found dead with all organ of her was

3. disappeared. The situation, like this, can be a serious social problems.
Economics:
As every surgery does, the cornea transplant also costs a lot of money. According to some
article we need 7,500~10,000 dollars to get cornea transplant. The expensive price also
can be a problem and related with economics issue and social issue. Some poor people cannot
get the transplant because they do not have enough money. The situation is unfair and they
may be able to commit a crime. That’s why I said the issue was related with social issue.
Anyway almost prices of operations are expensive and it always cause some problems. For
examples, a man who really needed some money to get surgery, so he committed robbery
lots of money. but he was placed under arrest. Even some people kidnap because of
expensive operation prices.
Conclusion:
In this essay, many information about cornea transplant were discussed together with social
issue, ethical issue and economics issue also the benefits and limitations, some problems
caused by cornea transplant.
I think my topic is interesting but it is difficult. I did not know in detail about cornea transplant
before writing the essay. And many problem and crime caused by cornea transplant. To solve
the problems, the government have to tighten up the law and punishment. If the punishment
become stronger, the cruel crime decrease. I wish the cruel crime that I have mentioned before
was disappeared.
