In these pages we have taken a look at the femtosecond laser and IntraLase technology. But we have only just scratched the surface of the genius and development of this natural miracle. Humankind once thought the earth was flat, and sometimes I think it still is, especially when I’m driving for hours across the desert on a midsummer’s day, wishing I were only dreaming on a cool night.

Well the history of science is fascinating, where we see practical instruments and theories giving way to new ones as the old ones no longer “work.” While the microkeratome—the predecessor of IntraLase—may still be used by some LASIK surgeons, it may also be going the way of the flat earth.
