I live in Georgia and have heard that although not as substantial as

interested in custom-wavefront but not sold on it by any means. Does
anyone know any value-conscious places in Canada or elsewhere in the
US that still do good work?

You may want to post this to:

I went and got a free pre-screening at a local place and their prices
weren't appreciably less than Emory Vision (not that I begrudge Emory
to charge what they do), so I figured I'd keep looking.

I'm -2.25+, my wife -3.25+ both with Astigmatism < -1.

Any suggestions as far as to specific practices or locales? Any place
besides Canada worth looking into? And yes, please spare the "you
can't place a value on your eyesight" business.

Sorry, but ... I fully expect you'll hear QUITE a bit of that ... and
that you should hear it.

Neil is correct. You really can't place a value on your eyesight.

This is a topic that I have put a great deal of research into. I'm
going to try and show the facts as I believe they are, if you really
want to get to the bottom of Lasik you have to go find the scientific
journals and scour them as I have. This information is out there, but
you won't find it on some slick lasik advertisement.

Lasik:

Lasik is no where near as safe as surgeons will lead you to believe
and now that some facts are starting to get out many of these lasik
surgeons are starting to leave the practice and move to other laser
ablation techniques.

Your eye will never ever ever ever (ad infinum) heal, ever. Your flap
will always be suseptible to tearing, especially from a blow sideways
to the eye. The best numbers that the limited research can provide is
eventually the inside of your eye will regain 2% of its origional
strength and the outside layer will recover to 12% (I can't remember
this number perfectly, my mind also wants to say 8%).

Surgeons also make creative "lies" about their results. As most eye
doctors seem to do, they only measure your refractive error. This is
getting better as they look at the surface of your eye with a corneal
topography and can see when they've totally screwed up, but you can
get 20/20 "perfect" vision and be utterly crushed by blinding
sideaffects (common examples are: glare, halos, night time vision,
double vision and so on). From what I hear in personal stories, it is
more profitible for the surgeon to kick you out the door and take in a
new patient than it is to help you with your train-wreck vision. Not
all practices are like this though so if you decide to do this pick
very very wisely.

There is no practical difference which way the flap is hinged, new
lasers that track your eyeball movement don't work 10% as well as they
claim and many surgeons turn off those features as they interupt the
surgery a disconcerting number of times because of movement in your
eye. Machines are often poorly calibrated and poorly maintained.
Surgeons do not sterilize their surgery rooms. If any debris is
trapped under the flap things can go bad fast. This surgery is not
suitable for high refractive errors, as you would need to sacrifice
too much tissue in the eye and jepordize its safety.

Surgeons exagerate the quality of their lasers. Go to the FDA website,
you can get some no bs studies there on the success rates of various
lasers.

Now there is emerging a new type of 'microkeratome" on the market.
Instead of cutting the cornea with a microkeratome, which is not as
accurate as surgeons will tell you it lasers the flap into your eye.
This technology has not shown promise and it does increase the risk or
haze formation. Another thing I should mention to you is that the
device used to hold the eye still during this part of the procedure
compresses your eye flat. Pressures are known to increase many fold
causing increased incidence of floaters (big ones, not little ones) as
well as other things, including overall structural weakness of the
eye.

Now, as most people seem to speak of lasik surgery, but use it to
refer to all types of refractive surgery I will cover some more types
for you.

Radial Keratotomy/Diamond Microsurgery:

If your surgeon tells you that you are not a canditate for any
surgery, save for this one, this is god telling you that you can not
have refractive surgery.

RK features unpredictable results, changing refractive errors and a
ridiculously high level of side effects. You will never be able to
withstand high or low pressures either.

Now that being said this surgery did start out extremely positive. It
started in Russia with a very good success rate because the doctors
were not fixated on profit. They were willing to split the pie and
stick to their one task, doing it to perfection instead of our current
jack of all trades doctors.

Long story short: this is an extremely old, unreliable techniqiue that
no self respecting surgeon would perform.

LASEK/PKR/EPI LASEK/Surface ablation techniques:

The close cousin to LASIK and the flap surgeries, surface ablation
works in an almost identical manner, except the laser is applied to
the surface of the cornea without a flap being made. This is making a
big comeback in recent years as people are realizing the dangers of
lasik. These techniques are documented to have a greater risk of the
refractive error returning, greater discomfort and a greater
probability of haze forming.

These techniques are not suitable for patients with high refractive
errors, the higher your refractive error the greater the risk for haze
development. Some surgeons use Mitomycin C on your eye to keep haze
from forming. This practice is not fully researched yet. It does
appear that it stops haze from forming in some patients, however it
also kills alot of the stuff it touches in your eye.

Now this surgery spares your eye the looming threat of the lasik flap,
but it comes at a high price. In the process of ablating your eye the
Bowman's membrane is irreversibly destroyed. It will never grow back.
The Bowman's membrane it thought to contain a fair potion of your
eye's ability to filter out high energy radiation. the side-effects of
sacrificing this membrane are not fully researched.

There are other surgerys out there like inacts, or phyiscally placing
a lens infront or behind your iris, but I believe these techniques are
far too new to even be considered.

Believe me, I wanted this surgery to be the miracle solution it is
touted to be and it can be, but the risk factors are simply too large
for me to ignore. I would say that if you needed this to pursue a
dream job or something of that nature then the choice is up to you. If
you are only looking to get rid if your glasses, this is a serious
gamble considering the limited benefit you can derive from it.

The above post is pure crap. This person knows nothing about lasik but
just parrots the rants of lunatic websites.
