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.

Modern excimer Laser surface ablations are totally painless during the procedure as well as in the follow ups. However the vision will recover fully in 3 to 4 days, unlike Lasik where it is few hours. However it is a boon for those with thinner corneas & aberrations.

he said he needed something stronger since he was gonna operate with a laser
(the only thing they used numbing drops on me was for checking eye pressure) =P
when i say “numb”, after he gave me the shot, my eye got lazy, slowly drifted away from whatever i focused on, basically losing any control over it.
Well , I got that …
Well , I got that part . They could have just used numbing drops .

Jehovah
The personal name of the only true God. His own self-designation. Jehovah is the Creator and, rightfully, the Sovereign Ruler of the universe. Jehovah is translated from the Hebrew Tetragrammaton, ????, which means He Causes to Become. These four Hebrew letters are represented in many languages by the letters JHVH or YHWH. Mark 1: 14 Now after John was put under arrest Jesus went into Gal´i•lee, preaching the good news of God
I hope I can get …
I hope I can get this answered as soon as possible, because I would be meeting with my optometrist in about a month on PRK and Lasik, procedure and risk wise.
I know he’d avoid telling me the CORRECT risks, so I’m here to impose the question on to you guys:
1) Which is safer? They say 95% of Lasik surgeries comes out perfect. What about PRK?
2) Which operation has the LEAST amount of risks?
ya know, i had to …
ya know, i had to get laser surgery for retninal problems…but before that, that had to inject a needle in my eye. IT WAS PAINFUL AS FUCK!!!! KEPT IT IN THERE FOR A GOOD 2 MIN!!!

ive often wondered …
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!
