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.
The reading and the lecture are both about the eye surgery, its effectiveness and costs. According to the reading passage, the weaknesses of the surgery and related with the operation high costs make those surgeries unlikely become popular. The lecturer casts doubt on the claims made in the article. By using the following evidence, she posits that neither high costs nor long healing time is accurate constituents of the procedure.
To begin with, the professor contends that the price per surgery is decreasing, demonstrating that the actual decrease in price has already reached thirty per cent for just several years. The growth of competition among different surgeons and technological boom both constitute actually to the decrease in price of such procedures. This statement counters the authors point, according to which the price of the eye surgery grows up, driven mostly by an increase in the cost side of the medical procedure. Likewise, the author does not take into account the technological developments and makes his assumptions, saying that the cost of surgery is positively correlated with the use of high quality machines.
Furthermore, according to the lecture, his people who meet post-operative problems are usually extremums. The professor demonstrates that patients with side effects behaved inconsistently with the healing practice, climbing on Everest, where the pressure is much higher. She states that it usually takes no more than three days to recover from the operation. This point differs from one in the article, according to which it usually takes long to recover after the surgeon intervention. Moreover, the author points out that the marketing efforts try to confuse patients with the wrong information about quick healing.
By the same token, the lecturer puts forth the idea that it is extremely uncommon to return to the surgeon in order to repeat the procedure after a short time period. She states that the humanity has cases which demonstrate the long-lasting effect of the surgery and it could take more than twenty years to deteriorate again.
All in all, the evidence referred to by the lecturer challenges the idea that the eye surgery will never become popular among public.
