i'm REALLY thinking about it...

[Archon]

...but i got some questions, here's my prescription :

23 years old
Right eye : -1 sphere, -2 cylinder
Left Eye : -0,5 sphere, -1,5 cylinder

i got 12 secs with lacrimal film breakup, 600 microns per eye of cornea thickness, 4 mm diameter pupil in light condition (still don't know how much in darkness)
15 mm at Schrimer test

Problems pre-op :

1 - i got floaters
2 - i got keloid scars formation on chest

My questions :

1 - Will floaters disturb me more after the surgery ?
2 - Will i need a second surgery with my high astigmatism and low myopia ?
3 - Thinking about a surface procedure, really dont like flaps, i'm planning to do it on Pulzar Z1 Laser, anyone here got any experience with this laser ?
4- Should i avoid smoking pre/post op ?
5- better custom or wavefront optimezed ?
6-i've read that Ultaviolet of laser causes dry eyes, and a clinic offers a way to dismiss the ultraviolets and provide less chanche of developing dry eye, anyone heard about this thing ?
7- What is the statiscally odd to get 20/20 with my prescription at first shoot ?
8- How the surgeon calculate the exact amount of microns to ablate ?

Thanks for anyone wanting to reply

Keloid formers do not seem to have any trouble with Lasik. See Lasik and Keloid for more details.

1 - Will floaters disturb me more after the surgery ?

It is possible.

The underlying cause of the floaters may be exacerbated by Lasik. A vitreous/retina examination by a sub-specialist can likely determine if you are at elevated risk of a problem after Lasik.

The process of Lasik can disrupt the floaters that already exist, moving them to a different location. The brain tends to learn to "ignore" floaters at a specific location and after a period of time. If the floaters move, the brain needs to learn to ignore the new location.

Lasik changes the focus of light within the eye and this may make floaters more "seeable". Like new floaters or floaters that have moved, the brain will need to learn to ignore the floaters as much as is possible.

See Lasik and Floaters for details.

2 - Will i need a second surgery with my high astigmatism and low myopia ?

Not necessarily. Your high astigmatism combined with low myopia will be a bit more challenging, but is well within the treatable range.

See Lasik and high astigmatism.

3 - Thinking about a surface procedure, really dont like flaps, i'm planning to do it on Pulzar Z1 Laser, anyone here got any experience with this laser ?

The Pulzar is not approved by the US FDA, so I have very little knowledge of its practical use. From articles I've seen, it appears to be as good if not better than anything US FDA approved. Perhaps our European visitors will be able to comment.

4- Should i avoid smoking pre/post op ?

Frankly, it is my opinion that no one should smoke unless they are on fire. Except for the day of surgery, there really is not much need to avoid normal smoking habits.

5- better custom or wavefront optimezed ?

"Custom" and "wavefront-optimized" mean the same thing. What you may be seeking is whether or not you should have conventional or wavefront-guided. This is really up to your doctor and his/her personal experience with his/her laser for previous patients with similar refractive error. Ask the doctor which is recommend, and then ask why.

See wavefront custom Lasik.

6-i've read that Ultaviolet of laser causes dry eyes, and a clinic offers a way to dismiss the ultraviolets and provide less chanche of developing dry eye, anyone heard about this thing ?

To my knowledge there is no scientific evidence that the wavelength of the excimer laser caused Lasik-induced dry eye. It seems to be more related to the change in the curvature of the front of the cornea and disruption of the nerve cells within the cornea.

See Lasik dry eye for more details.

7- What is the statiscally odd to get 20/20 with my prescription at first shoot ?

I do not know of a study that provides this information. What you can do is ask your doctor to review the patients s/he has treated with this script and look at those results.

See Lasik resultsfor more detail.

8- How the surgeon calculate the exact amount of microns to ablate ?

The laser's computer will do this. The doctor can see the treatment plan prior to surgery. As a (very) general rule, about 12-18 microns per diopter of refractive change is the norm.

Thanks Glenn for the reply !

By wavefront or custom, i meant wavefront guided or topography guided ablation !

Also i did a wavefront analysis with ZyWave, but still i cant understand the results, does it measures HOA ? If the answer is yes, how can i understand it ? :)

Im a bit afraid since i think i already got "natural starbusts" and thinking that maybe the surgery would increase whatever mother nature gave me!

So changing the cornea curvature may increase dry eye ? I got 2 cylinders of astigmatism so defintly after the surgery i will change my curvature, and this may be a risk to develope dryness ? am i right ?

I already read your article on astigmatism correction, and i fear i would get into hyperopia :(

[It's Just Me]

One comment that was helpful to me that the doctors told me....each eye heals DIFFERENTLY. Some heal faster than others. Each eye reacts differently to correction. And, there's a chance of "loss of best corrected vision" Which just means you won't get the vision you had with contacts or glasses.

I think I might be experiencing that right now.

My auntie had lasik last week and she had dry eye for at least seven days. All of the skin around her eyes also went dry and wrinkly - is this a symptom of dry eye?

You may want to look at our article on Lasik higher order aberrations (HOA) and wavefront-guided surgery.

Yes, this can be a symptom of dry eye. It can also be the symptom of something else that contributes to dry eye. You may want to read our article about Lasik and dry eye.
