great to hear of the successes! now there is no knife - they laser
off the top layer with 'interlase'. then it is
'custom lasik' based on individual contour.

the doc said 10 day wait for a swimming pool and 4 weeks for water
sports. i do plan to take the 4 weeks (well, what if there's a
*perfect* day after 3, we'll see if i can resist). i mostly wanted to
be sure no one had big crashes that lead to troubles. it's rare
my crashes are face plants but there's always a first...

the whole procedure is crazy to watch!!

sort of like peeling back the an orange peel partway, removing some pulp and putting the peel back in place

From what I remember I heard the Cornea is one of the fasting healing tissues in/on the human body

after my laser surgery my Dr. had me wear an oversized contact lens to keep out infection but he took it out the next day after "I" drove in



the whole thing even ranks above getting a ZeroGravity board as far as money well spent

i wear sunglasses while boarding, and they are held on even tighter when I wear a helmet. I still haven't lost a pair

I imagine you would have to have a major crash to knock off swim googles under helmet straps.

My brother had this done and is very happy with the results.

I have a friend who went blind from the same procedure due to complications.

DO YOUR HOMEWORK! Don't just let anybody cut open your eyes!

And you might consider getting one eye done at a time, in case something goes wrong.

I had lasik done on one eye (-0.75) 8 years ago in france, (no cutting involved), it sure was money well spent.

funny part during the surgery is when you can actually see smoke coming out of your eye (with the other one) from the burning tissues.

only issue i had was with the healing process because of very dry eyes, it took about 12 months. In some conditions, too much light was projected on the healing cornea thus creating a foggy vision.

the eye specialist recommended the same 4 weeks before going for water sports.

Just had the surgery 3 weeks ago and pretty happy with the results :D

I was told 4 weeks also for water sports, I would take this as the minmum I wasited until the off season to have mine done just to help.

It is great being able to see without glasses or contacts

You should only consider laser correction if your prescription has been stable for several years. If you prescription is changing at all then there is no point in having your eyes corrected because they will change again.

Your eye surgeon is supposed to assess your suitability for laser correction and to hand-hold you the whole way through. It takes about 6 months before the process is complete and you should be able to go back at any time for minor adjustments (not more laser surgery) and hand-holding.

My guy was pretty well known and respected in the medical world and had heaps of publications and did lots of ersearch. I would not gop to some cheap shit clinic that just takes your money and churns you through.

With PRK they use a blunted scalpel to remove the epithelium, which is the outer surface of the eye. They then clean the remaining tissue off before lasering. It is quite a strange feeling to have two 6 foot, 80kg guys leaning on your eyeball poking it with a blunt scalpel and scrubbing away at it with a piece of gauze. The blunt scalpel cuts the epithelium but does not damage the underlying cornea.

Before all this you are given a couple of tranquilisers and cocaine drops to the eyes so you feel no pain and are full of peace and happiness to all men. :)

They then laser you while you keep your eye focussed on a dot of red light. Of course, the red dot seems to be skating all over the place. There's a smell like someone is burning the bacon. That's your eyeball being lasered. They have to monitor the humidity in the room and the moisture content of your eye so that you get the right quality of burn.

When it's all finished they pop the flap of ephithelium back on and bandage your eye. The next morning you take the bandage off and you can see. Over the next 6 months you have steroid drops which are used to manipulate the internal pressure of your eyeball so that yuo end up with the best possible result. You vision can vary a bit during this time.

Lasik is the same except they cut through the epithelium and straight into the cornea and just fold the flap over. Once they have finished lasering they just drop the flap back into place and you can see straight away. You still need the after care and adjustment with the steroid drops.

The older system just laser out a divot from the middle of the cornea which focuses light on the centre of your retina. In low light conditions when your iris opens wide up you can get light around the edges of the corrected bit which causes back-scatter. Your vision is less crisp in low light. Once it get's back to darkness the back-scatter stops and yuo have razor sharp vision again.

The new lasik systems actually re-shape a much bigger section of the cornea and reduce the back-scatter effect in low light. Thet can also correct astigmatism.

Never in hell would I have my eyes sliced.

I have some cool sunglasses (prescription) and a pair of "chums" to hold them on. They're reasonably comfortable and have UV protection.
