Over Fifty Years of Changing Medicine

Dr. Tennant was instrumental in or contributed to changes in the way ophthalmology was practiced in his lifetime.

 

 

Here are several of the ways Dr. Tennant has made an impact in ophthalmology: 

  • Developed the techniques to safely implant intraocular lenses after cataract surgery, eliminating the disabling thick cataract glasses

  • Developed better and safer intraocular lenses

  • Developed the water-tight beveled incision to allow immediate ambulation after cataract surgery eliminating the need for patients to stay in bed for 2-3 weeks after cataract surgery

  • Developed a plastic dome patch to be use after eye surgery to avoid the unnecessary and uncomfortable pressure of standard patches

  • Developed techniques for saving eyes that hemorrhaged during surgery

  • With the anesthesiologist, Monte Hellman, MD, developed the techniques for safe outpatient eye surgery and opened the first outpatient eye Surgicenter in Texas

  • Lobbied congress to pay for outpatient surgery, resulting in savings of billions of dollars and patients avoiding the hazards of hospitalization (falling in strange surrounding, hospital infections, hospital medication errors, etc.)

  • Along with Dr. McIntyre and Dr. Williamson, started the Outpatient Ophthalmic Surgery Society to teach ophthalmologists how to safely perform outpatient eye surgery

  • Trained ophthalmologists around the world to safely perform intraocular lens surgery. This included textbooks about cataract surgery, IOL surgery, and phacoemulsification

  • Did the majority of the FDA studies for the VISX laser for use in refractive surgery

  • With Dr. John Corboy and Dr. Malcolm Ing, was the catalyst for forming the Royal Hawaiian Eye Meeting, the third largest eye meeting in the world

  • Developed new theories explaining that acupuncture meridians are actually stacks of rechargeable muscle batteries, forming a power supply for every organ in the body

  • Found that the power supply to the macula is the stomach acupuncture meridian

  • Found that the power supply to the optic nerve and retina is the liver acupuncture meridian

  • Found that the power supply to the drainage system of the eye is the sympathetic acupuncture meridian
