PRK is among the most effective treatments available to treat a wide range of vision related impairments which include astigmatism, myopia and hypermetropia. Although a lot of people in Sydney are now going for lasik treatments but there are still many who consider PRK as first choice. But the unfortunate side of the story is that there are a lot of who doubt the very efficacy of this treatment. This is mainly because of the prevalence of scores of misconceptions related to this treatment, which are usually spread by misinformed people. Here are some of those myths which people usually tend to encounter on a regular basis:
•Myth 1: PRK treatment cannot treat astigmatism
Fact: A lot of individuals in cities like Sydney and Melbourne live with this common misconception that this treatment cannot prove effective for eye related problems like astigmatism. However, this is totally untrue because PRK treatment is almost as effective in treating this problem as LASIK surgery. There is a very minor percentage of people who have such a high prescription that it can neither be treated through PRK nor advanced laser treatments.
•Myth 2: The patient cannot move his or her eyes during the course of the treatment
Fact: Again this is nothing but a huge myth or misperception. This is because although the patient is asked to keep his or her eyes focused on the target light, they are not supposed to keep their eyes perfectly still during the treatment. An advanced pupil tracking technology is used for this treatment which keeps a track of even minor movements of eyes, thereby ensuring that the person is not required to keep his or her eyes still while the surgeon is performing the treatment on their eyes.
•Myth 3: The results of the treatment do not last for a long period of time
Fact: It is true to some extent that the prescription of the human eye can change after a certain period of time, but that goes for people who have not had any PRK treatment ever. Therefore, before you opt for such a treatment, you need to ensure that your prescription has remained stable for a considerable period of time in order to get the best results.
