From a recent Sacramento Business Journal article:
"About 715,000 people are expected to get 1.2 million eyes zapped this
year, according to David Harmon, president of Market Scope, a St.
Louis-based research firm that tracks refractive surgery. That’s down
about 10 percent from 791,000 people and 1.3 million eyes in 2001. "
I believe that the number may be a bit lower than Harmon’s
projections, but his people have been the best predictors and analysts
of refractive surgery volume for many years.

My surgeon says his practice is down from last year. One of the
reasons he gave was 9-11!!

Your eyeglass prescription may change slightly from year to year but
it doesn’t have to be due to the changes in the shape of the cornea or
eye. Just one other possibility is that the lens in the eye changes a
little (with the development of cataracts for example) causing the
prescription to change.
No– a new prescription is not needed simply because your eyes "get
used to the glasses".
Changes in glasses are usually do to one or more of the following:
-changes in the shape of the cornea (common)
-changes in the focusing ability of the lens (e.g. presbyopia or
decompensation with hyperopia)
-changes in the refractive properties of the lens (e.g. development of
cataracts)
-changes in the axial length of the eye (usually in kids and
adolescents)
-transient edema/swelling of ocular tissues (e.g. uncontrolled
diabetes)
