Eye surgery options for nearsightedness
People who were born with nearsightedness have probably worn glasses for much of their lives. Or, if someone has developed nearsightedness as they have grown older may be in the process of discovering which remedy will best fit their specific needs. In recent years, technology has advanced to make corrective eye surgery possible for people who suffer from nearsighted vision. These procedures are fairly simple, and require minimal recovery time. Here is an overview of several types of eye surgery options that are available for those who suffer from nearsightedness.
Photorefractive Keratectomy (PRK)
Photorefractive Keratectomy, also referred to as PRK, is a form of laser surgery that removes tissue from the eye's surface to change the curvature of the cornea. This was the original form of eye surgery, and it was first started in the 1980's. It was fully approved by the FDA in 1995.

Doctor's moved away from PRK when new technologies emerged, however, it has started to make a comeback. Doctors have started to use PRK more often for several reasons. First of all, PRK produces similar outcomes to more modern surgeries. Also, studies show that nerves tend to regenerate faster after a PRK surgery as opposed to other types of surgery which may cause the eyes to experience less dryness during recovery time. PRK is often the best option for people who have a thin cornea. One of the drawbacks to PRK is that there tends to be a little more discomfort immediately after surgery. However, if a person is willing to sacrifice a little pain up front for a more pleasant recovery, PRK may be the route that should be taken.
Lasik Surgery
Another form of eye surgery is Lasik. Lasik is a more modern technique that has become widely popular among people searching for corrective eye surgery. There are several forms of Lasik known as Lasek, Epi-Lasik, All-laser Lasik. Each of these methods accomplish similar results through slightly different techniques. Some include alcohol, while others employ special cutting tools.
In most cases of Lasik however, the process includes cutting a hinged flap in the eye's surface and folding it back. Then, laser energy is applied under the flap to reshape the eye and remedy the nearsighted vision. Then the flap is folded back over the eye and serves as a natural bandage.
Implantable Lenses
Another option for people searching for ways to correct their nearsighted vision is to have permanent lenses surgically implanted into the eye. This method is the best method for correcting severe nearsightedness. These permanent lenses were approved by the FDA in 2004. They are very similar to contact lenses, only without the daily cleaning and constant worry that they will fall out. These types of lenses are also good for older people looking to correct a new change in their vision. Instead of having to develop the habits of constantly wearing glasses or caring for contacts, a person can simply have them implanted and carry on with their life.
Not a Cure All
Vision surgery, no matter which kind is chosen, is not a cure all for every form of nearsightedness. Some very severe forms of nearsightedness might not be completely curable, or vision surgery might not be possible. The best option is to consult with an eye doctor to ensure that the best form of correction for nearsightedness is chosen.
People suffering from nearsightedness may have an alternative solution to the problem through corrective eye surgery. Whether a patient chooses to have PKR, Lasik, or implantable lenses, clear vision is closer than one might think. These procedures can fix most forms of nearsightedness, and recovery time is not extremely long.
