The following results were obtained in the FDA LASIK Clinical Trials in
2002. These statistics are from the laser manufacturer, using the best
doctors in their trials.

Table 12, page 17;



36.6% night driving problems worse

37.7% vision in dim light made worse

42.9% haloes made worse

37.9% blurred vision made worse.

Your message was useful in showing why the B&L Technolas is not a good
laser system and why just about nobody uses it. Find a study on the
market leader - VISX please.

Anyway, I would suggest that if someone finds out their surgeon is
using the Technolas, Nidek, or Ladarvision system... go someplace
else.
LVI has a slick trick. They have both the VISX and NIDEK systems,
however, they count on their patients not knowing the difference, and
at the last moment they decide to use the NIDEK. That is like
ordering filet mignon and the waiter substitutes salisbury steak.

Anyway, if you go to nearly the bottom of the pdf link below, you will
notice that off all the patients in the study, only 2.6% of them were
dissatisfied. If this is the most negative data you can find, then
everyone with myopia should RUN to their nearest LASIK surgeon.

Also, I have a feeling that whoever wrote that study was an idiot. If
you look at the chart from where the numbers below are pulled, you
will see that these same patients had virtually no complaints about
astigmatism, haze, floaters, or starbursts.
How can roughly 40% of these patients be complaining about halos and
blurred vistion when less than 1% of them are complaining about
starbursts and haze? That is a severe contratiction.

"High percentage" is relative. According to our Quality Standards
Advisory Committee, approximately 3% of refractive surgery patients
will have an unresolved complication at six months postop with 0.5%
being serious complications requiring extensive maintenance or
invasive procedures to resolve. Most studies show the loss of best
corrected visual acuity for current procedures to be within these
percentages.

For some, 3% may seem high. For others, that may seem acceptable.
