Cosmetic Surgery
Surgery that can improve the way a person looks is becoming more and more
popular in the United States. This kind of surgery is called cosmetic surgery,
and both men and women are turning to this treatment as a way of keeping their
appearance young as well as keeping competitive (有竞争力的) in their jobs. Men
especially are beginning to turn to face-lifts (面部拉皮手术), liposuction (taking fat
out of the body), and implants (putting artificial parts into their bodies) to
help them look younger. As companies downsize (编造) and move younger employees
into higher positions, older employees in their late forties and early fifties
feel the need to look and act younger in order to stay competitive. These
operations are not without dangers, however.
One young woman
had an eye operation to get rid of the bags under her eyes. She described her
experience as terrible. She said, "When he started cutting, I was fully awake.
Even though he’d given me an injection near my eyes, I saw everything." She went
on to explain, "I knew I had to keep still because of what he was doing. He was
scraping (刮) away fat underneath my eyes. It took about ten minutes. After he
finished, I felt I couldn’t walk. I was so faint." Her troubles did not end
after the operation for two weeks. Her eyes were swollen (肿胀的) and almost
completely closed, and even dark glasses could not hide the side effects of the
operation.
Liposuction, taking fat out of the body, is probably
the most popular cosmetic operation in the United States. It seems simple
enough. First, a small cut is made over the place where the patient wants the
fat removed. Next, a small pipe is put into the cut. A machine like a vacuum
cleaner is then used to suck the fat out of the body. However, as one doctor
explained, some problems call happen after the operation. He warned, "Irregular
lumps and loose skin can reset from this operation. If it is not evenly done,
liposuction can produce a very lumpy result." Patients often must have more
liposuction to correct the problem.The eye operation was such a failure that the woman refused to pay for
it.
