Laser Vision? Eye Science Living Geniuses and The Excimer Laser:

Have you had, or do you know somebody that has had, laser vision? Dr. Stephen Trokel, trained in physics, engineering and ophthalmology (visual science), still today in practice at Columbia, invented it! It's wildly amazing to even just read about it. This excerpt is taken from literature I read late yesterday regarding Dr. Steve Trokel:

In the early 1980s, the field of ophthalmology was entering a new era, an era driven by the revolution in laser technology. At that time, while Dr. Trokel was working as a clinical and research professor of ophthalmology at Columbia University, ophthalmologists began using lasers in surgery. “It was like magic for our field,” said Dr. Trokel about the moment when he became interested in using lasers for refractive surgery.Dr. Trokel was fascinated by this idea and began studying prior laser surgery techniques and made various conclusions of his own, which he documented in several published papers. Dr. Trokel was particularly interested in researching the effect that the excimer laser would have on the human cornea.

The excimer laser, which was invented in the early 1970s, is an ultraviolet chemical laser that has an extremely sharp focus, capable of performing very delicate and precise surgeries, such as eye surgery. “I was astonished, as was everyone, at the precision of the tissue removal by laser,” said Dr. Trokel. “On this small foundation, the technology of excimer refractive surgery was built.”


And this in turn led to what we now know is laser eye surgery! The story of how I learned this is a personal one but has nothing to do with my own visual science genius, Dr. N. Azar, and she works closely with other eye science geniuses at/from UIC, Department of Ophthalmology and Visual Sciences.

Moreover it's outstanding what human's are capable of, yes?
