Dr. Tennant did the majority of the research for the excimer laser for VISX that is used for LASIK surgery. He did about 1000 cases in the U.S. and
about 2000 cases abroad.

What wasn't known was that the laser wouldn't kill viruses in the cornea. As seen in the photo, the laser would strike the eye releasing viruses. They came
upward through Dr. Tennant's mask, into his nose, and into his brain. He
developed encephalitis and a bleeding disorder. This resulting in his
being unable to remember how to write a prescription and in spastic
movements. Three viruses were found in his brain and he was told nothing
could be done to help him. He was forced to retire from ophthalmology
on November 30, 1995.

This is how he spent the next 6-7 years, sleeping about 16 hours per day. He had 2-3 hours a day in which he could think clearly enough to understand a newspaper. Then,
like a light switch, the brain would shut off and he couldn't understand
what he was reading.

Note that the dogs seemed to sense the problems. One would lay on the head (encephalitis) and one near the stomach (spleen). Since he is well, they no longer do this.

During the time he could think, he realized he would have to find a way to get himself well since modern American medicine could not do so. He began to read
cellular biology books with the idea that if he could get one cell to
work correctly, they would all work correctly.

Each
cellular biology book gave passing notice to the fact that cells
require a narrow range of pH, but little more was discussed on the
subject. He began to look at pH and discovered that it is a measurement
of the voltage in a solution. It is measured with a sophisticated
voltmeter. If the solution is an electron donor, a minus sign is placed
in front of the voltage. If the solution is an electron stealer, a plus
sign is placed in front of the voltage. The measured voltage is then
converted to a logarithmic scale from 0-14 with zero corresponding to
+400 millivolts of electron stealer to -400 millivolts corresponding to a
pH of 14. Cell are designed to run at about -20 millivolts (pH 7.35).
Dr. Tennant began to understand that cells must have enough voltage to
work and that chronic disease was associated with loss of voltage. Next
he had to find out how to measure the voltage and then how to correct
it. This is how he was able to heal himself.
