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

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.

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

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.

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.
Archon wrote: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.

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.

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.

Archon wrote: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.
