Patient ED @ 617-379-1582 INFO
Your doctor has recommended that you undergo Photorefractive Keratectomy – or PRK Laser surgery – to correct a vision problem. But what does that actually mean?
The human eye is constructed like a camera …with a clear lens in the front and light-sensitive tissue at the rear. This tissue makes up the retina which acts like photographic film.
In an eye that has perfect vision, light rays passing through the pupil are focused by the lens to fall precisely at the center of the retina. There are many common problems that can affect the eye and prevent light rays from focusing properly on the retina.
Three of these problems, myopia – or nearsightedness; hyperopia – or farsightedness; and astigmatism can often be corrected or reduced with the use of PRK laser surgery.
Myopia, or nearsightedness, occurs when the shape of the eye is too long or the curve of the cornea is too extreme. In this case, light rays are focused on a point in front of the retina – instead of on the retina itself.
Hyperopia, or farsightedness, occurs when the shape of the eye is too short. In this case, light rays are focused on a point behind the retina.
Astigmatism occurs when the cornea is unevenly curved,
causing light rays to fall off center or not to focus properly at all.
In either case, PRK laser surgery can be used to flatten all or part of the cornea …allowing your doctor to cause the focal point of light entering the eye to fall more closely to the center of the surface of the retina.
PRK is a simple and nonintrusive procedure that is designed to reduce or eliminate the need for glasses or contact lenses. PRK laser surgery generally does not have any effect on a patient’s overall health and there are no risks in choosing not to have the surgery.

ive often wondered this myself, i am 16 and have terrible eyesight, i think that its a possibility that if i get my shortsightedness fixed, my eyes will just get worse over the course of the next 16 years until they are back to where i am now!

‘there are no risks in choosing not to have the surgery’ that insanely stupid phrase just put me off.

Yeah thanks, I actually just had to get new glasses, it was a small change, but a change none the less. I didn’t ask about surgery, I thought if they’re getting worse laser surgery will fix it, but it’ll more than likely still hit a decline untill my prescription levels out.
Oh well glasses it is
Be very careful. At …
Be very careful. At age 20, people eye changes and they need higher point priscription glasses every year and eyeglass from last year become useless. What if your eye also get change after surgery, does it mean you would need another corrective surgery?
However there is a surtain age when eye finally stop at getting worse but its different for everybody, doctor says its age 22 but its not true.
Make sure you talk to different doctors about this procedure before letting them cut you open.

Does laser sergery like this wear off eventually? I’m 20 and thinking of having it done, although I’m highly sceptical and most likely will get contacts, I’m just wondering…….I don’t want to go and have it done in my mid 20s and find out later down in the line my eyes are going to get worse, and eventually make it pointless, rending another surgery helpless?
