In the past several years, a number of technological advances have made laser eye surgery more widely available. The procedure uses tiny lasers to alter the surface of the eyeball, significantly improving a patient's vision. In spite of its growing popularity, however, laser eye surgery is a costly procedure. Given the number of problems that may accompany the laser vision correction procedure, it is unlikely that many will choose to undergo the surgery.
The first problem with laser eye surgery is the cost. The process requires sophisticated laser systems, which can cost several million dollars. In order to remain in business, the doctors administering laser eye surgery have to charge patients approximately $1,000 to $2,000 per eye. For many people, this is far too costly.
In addition, there are concerns about post -operative problems, which are issues that may arise after the surgery. There have been reports of the cornea (the lenses at the front of the eye) detaching themselves from the eyes after laser vision correction. Moreover, laser vision correction advertises a quick recovery time, but many patients report taking weeks and sometimes months to heal fully from the surgery.
It also remains unclear how long laser vision correction will last. A number of people have to go back to a doctor just four or five years after their surgery for another procedure. Even worse, others have to receive a second round of surgery just a few months after the initial procedure in order to perfect their vision. For most consumers, the benefit is not worth the risks and costs involved with the procedure.
Both the reading and the lecture are talking about the laser eye surgery and cons and pons of that. The article proposes that this costly procedure has several post operation drawbacks. It is not cost-risk beneficial for people. Conversely, the lecturer challenges the book’s information and asserts that those ideas are not accurate. Then he gives us more information to solve the misunderstandings.
First, the reading states that the cost of eye surgery is the first burden for people. It mentions that one to two thousands dollars out of the packet is not affordable for many of the people. On the other hand, the professor avers that there is some good news about the advanced new technologies which provide us cheaper technological instruments and eye surgery. In addition, the number of eye surgeons increased recently. This lead to more competition between them to attract patients. As a result, the more competition cause decrease in cost of laser eye surgery. He claims that nowadays the cost of surgery has decreased by 30 percent.
Second, the article points out that laser eye surgery has some post-operation adverse effects such as cornea detachment, which makes this procedure unfavorable. Controversially, the speaker rebuts this idea by mentioning that the laser eye surgery has not those kinds of adverse effects. He posits that just one case of cornea detachment has reported which it was related to high pressure of eye liquid, not the laser surgery. He explains that the average healing time for laser eye surgery is similar to other surgeries, something around a couple of days.
Third, the article mentions that another problem of eye surgery is the undefined lasting time of eyesight correction. However, the professor asserts that it is uncommon that a patient needs surgery again after months or years. He asserts that many cases have had a very good eyesight even after twenty years. He repudiates all the book’s information about the eye surgery problems and mentions that the cost is decreasing and post operation side effect is like other surgeries, also the duration of eye correction is very long.
