A Comparison between PRK and LASIK
In our daily lives, many sufferers of particular eye diseases tend to receive LASIK surgery and they can regain perfect vision as a result. But in some other cases, PRK is also very popular among some patients. In fact, PRK can get almost the same success rate as LASIK. But the two forms are not the same completely. Therefore, it is of vital importance for some patients to know the similarities and differences between the two surgeries.
Generally, in both of the two surgeries, patients will seldom feel any pain; some medications are needed after the surgery; it will take some time to recover; some common eye diseases can be cured by them, such as nearsightedness, astigmatism, etc.
As for the success rate, both of the two forms are very ideal and receivers can always get their perfect vision after the surgery. However, there are some differences in the operating process. For instance, sufferers of particular eye problems have to receive PRK only. Receivers of PRK will have to wear some special devices for some time. In the process of LASIK, a flap will be made. And the recovery time varies, too. There is no difference in their outcomes and the only point is one should find the form that suits him most. Therefore, one is suggested to consult with a well-experienced surgeon before taking the surgery.

Advantage of LASIK over eyeglasses and contact lenses
Good eyesight is crucial for most of our daily activities, from work to recreation. Vision always plays a huge role in various areas for everyone. Unfortunately, many people have failed to realize the importance of good vision to the quality of life. As a result, they suffer from types of vision problems including common refractive errors and even some eye diseases. Bothered by common conditions such as nearsightedness or farsightedness, patients must resort to external sources for help if they still want to get good or normal eyesight.
Until now, corrective eyeglasses and contact lenses remain as the majority in the realm of vision correction for common refractive errors. While offering their respective advantages, both eyeglasses and contact lenses do have disadvantages. The commonest shortcoming of contact lenses is try eye. Some contact lenses wearers forget to blink their eyes on a regular basis. There are still certain wearers who spend consecutive hours in front of a computer. In these cases, dry eye is very likely to occur.
Eyeglasses mean extra weight on the bridge of the nose. Even if there are available lightweight glasses, additional burden to the nose still exist more or less. This disadvantage may deprive wearers from being comfortable. Eyeglasses and contact lenses will often prevent wearers from participating in fierce activities such as swimming, diving and so on. During these recreational activities, spectacles and contact lenses are a hassle. What’s more, wearing eyeglasses or contact lenses may still affect family life. Parents wearing glasses or contacts are always concerned that their mischievous kids would break their eyeglasses or pull out their contact lenses.
A third treatment for common vision problems is LASIK eye surgery. This completely different solution can eliminate all of these disadvantages that are associated with eyeglasses and contact lenses mentioned before. LASIK procedure offers a permanent option and makes corrective eyeglasses and contact lenses needless.

Positive and Negative Reviews of LASIK
As a saying goes, every coin has two sides, opinions on LASIK vary from person to person. Some may hold that LASIK is a miracle that is able to make one see a clearing world waking up one day in the morning; while some may hold that LASIK is not good, complaining some post-operative symptoms.
As the case stands, either positive review or negative review depends on who you ask and no answer is authoritative and in full range for the reason that massive majority of all the LASIK reviews are not only positive but improve a person’s quality of life.
People having positive opinions describe LASIK to be wonderful, because having 20/20 vision is just a dream for most Americans who wear glasses. A LASIK surgery makes them no longer have to fumble around for their glasses or contact lenses, and they are able to lead a life as before when they were in good eyesight. The experience of consistent pushing up the glasses on noses and wearing and taking off contacts everyday has gone.
Although LASIK wins a large outpouring of favorable comments, certain amount of risks concerning LASIK are involved and some people give not so good comments. But they just list some events but never describe in details and seldom offer advices. Therefore, as a reporter, I’d like to read more negative reviews and look into some complaints. And if they are truly a problem I will report to the Better Business Bureau (BBB) for solution.
The good news is that majority of the reviews from both the patients and doctor are positive, which demonstrates that LASIK surgery, as a newly emerged in modern times, indeed serves us a lot.
FDA Approved LASIK instruments
LASIK is short for Laser-assisted In Situ Keratomileusis. LASIK is a FDA approved refractive laser eye surgery with the purpose of improving patients’ vision and reducing the need for wearing eyeglasses or contacts lenses.
The procedure of LASIK eye surgery mainly consists of three steps. The first step is to make a flap of the outer layer of cornea. There are two types of blades that can be used to cut a flap, the mechanical blade called microkeratome and the laser called keratome. The second step is to reshape the inner layer of cornea using an excimer laser. The last step is to replace the flap which is made in the first step.
There have been five instruments that used during the procedure of LASIK eye surgery have been approved by the FDA from the year 2000 to 2006.
