The passage and the lecturer are discussing about laser vision correction surgery. While the passage is describing problems with laser vision correction surgery, the lecturer disagrees with the reasons that the passage gave, stating those reasons misunderstandings.
First of all, the passage says that the surgery is very expensive, because of sophisticated laser systems. However, the lecture disagrees and says that laser vision correction surgery’s cost is decreasing. The lecturer states that this is because the equipment for the surgery is becoming cheaper, and extremely increased competition between the doctors who operates the correction surgery.
Second of all, while the passage states that the laser vision correction surgery cause severe post-operative problems such as cornea detachment and long recovery time, the lecture says the passage’s statement wrong. The lecturer says that such problems after surgery doesn’t occurs in regular situation, and also the recovery time is about two to three days after the surgery. The lecture says that cornea detachment- one kind of post-operative problem- occurs rarely from people who enjoys extreme sports, such as rock climbing.
Lastly, the passage claims that it is unclear how long laser vision correction surgery will last, saying that number of people go for another procedure just four or five years after surgery. On the other hand, the lecturer states that since the vision correction surgery is very effective, the patients who go back to doctor and receive procedure again.
To sum up, the lecturer disagrees with the passage’s claim that laser vision correction surgery causes a considerable amount of problems. First, while the passage says that the surgery is expensive, the lecture claims that the surgery is becoming much cheaper now. Next, the passage states that it can cause serious problems after the surgery, and takes long time to recover. On the other hand, the lecturer contradicts the passage’s statement by saying that post-operative problems rarely occur and recovery time of the surgery is only about two to three days. Also, the passage says that it is not sure how long the surgery will hold out, however, the lecturer states that it is not true that many patients go redo the surgery due to their tenacity.
