Hi Linda,
Honestly, I haven't thought about it much for the past 8-9 months, but
from what I do remember, the laser is built from the ground up,
hardware and software, to do completely custom treatments. It has a
very high frequency/refresh rate, and ablates less tissue than the
lasers currently used in the U.S. The companion topographer is
superior in that it provides measurements over the entire cornea.
Most of those in use now have a blind spot caused by the camera, so
the data for the central cornea is usually extrapolated. Learning of
this drawback was especially discouraging for those of us with
irregular corneas, because the central 2 mm of cornea are where most
of us have the most problems, and it's central to vision. Out in the
sun when our pupils are tiny, that's about all the cornea we see
through. Customized treatment for aberrated corneas using
extrapolated data (guesswork) is certainly not desirable. Traveling
to Europe was the only way to be treated on the iVIS laser, and
although I know of a couple of patients who did go there, having the
technology available in N. America will make it a far easier
journey.
I'm sure there are other advantages that I am missing so here is their
website:
Hi,
You may not know that the IVIS excimer laser has infringment of the
keralaser US Patent.
Please search US patent # 5,599,340 and 5,480,396
It is possibly copy cat and infring the patent.
The real origional company to manufacture the laser system is here:
