Lasik Helps U.S. Retain Pilots, Astronauts
The natural human aging process is in a constant war with the U.S. military and the National Aeronautics and Space Administration. Aging has always degraded the vision of Air Force pilots, Navy divers and NASA astronauts - and this has made it difficult for the respective services to retain them.
The government has always feared that eyeglasses and contact lenses could be broken or dislodged in the course of the service members' often grueling work, threatening life, limb and government property in the process. Even with the advent of Lasik surgery, the fear didn't subside.

Choosing Between Traditional and Custom Lasik
Lasik eyesight-correction surgery, a phenomenal breakthrough when it was first approved by the federal Food and Drug Administration in 1995, has recently been trumped big-time by the innovation known as wavefront Lasik technology, which is some 25 times more precise than its older cousin.
The consumer still has both choices available today - the traditional versus the new custom technique - but there is an enormous difference in technology.

healthwrap_video games
New research out of the University of Rochester shows video games that contain high levels of action can actually improve your vision.
People who played action video games for a few hours a day over the course of a month improved by about 20 percent in their ability to identify letters on a standard eye chart.

Visual DX
Bioterrorism is one of the country’s biggest post-9-11 concerns.
How quickly doctors can detect an agent of bio-war will determine how many people will be affected.
We’ve had a taste of how even very small releases of bio-terror agents can wreak havoc: the anthrax attacks after 9-11; the sarin nerve gas attacks in Japanese subways.
The threat of bio-war is very real today. Doctors making the first diagnosis need to be armed to be able to make a quick diagnosis.
Bio-weapons are diseases we simply don’t see. So, the key to protecting the public as the final line of defense is early diagnosis.
That’s where an E.R.-based computer program called visual dx comes in.
“Visual DX is really an incredibly powerful program that helps us in a number of ways but it was directed to us particularly to help us diagnose bioterrorism or potential bioterrorism cases,” says Dr. Lewis Kohl, Chairman of the Department of Emergency Medicine at Long Island College Hospital. “You can go in and put in a patient symptoms, you can describe what the rash looks like, what part of the body it is, how old the patient is.”

Early On-set Glucoma
Marina Virdone can’t imagine not being a school teacher. She says next to taking care of her own children, teaching is her second greatest love. But, three years ago, life as Marina knew it was about to change. Marina had developed a severe eye infection that eventually turned into glaucoma.
“I said, my God, I’m young and I have children. I can’t afford to go blind,” says Marina Virdone.
At the young age of 39, Marina was faced with the possibility of losing her eyesight if she didn’t seek glaucoma treatment. “I had always thought of it as a disease that affects the elderly,” says Marina.

Visual Process
The visual process is the means by which the eye perceives light and movement and translates these into nerve impulses.

New Lasic
Lasik is a new procedure that borrows technology from laser keratotomy and radial keratotomy to correct near sightedness and astigmatism. To correct near sightedness, doctors try to change the way light is refracted through the eye.

Blindness
The group of conditions known as retinitis pigmentosa or RP is the most common cause of inherited blindness. Initially the rods in the retina begin to die and the cones at the center of the retina, known as the macula, will also be lost.

INTACS EYE TREATMENT
Rekha Krishanmurthi has tried glasses and hard lenses to help improve her vision. But unfortunately, nothing is doing the trick.
“I can’t focus, everything is blurry. I can’t read and there’s no way I could drive or anything like that,” says Rekha Krishanmurthi. She has keratoconus, a progressive eye disease.

LASIK STUDY
If you’re considering LASIK surgery to get rid of your glasses, you might want to ask your doctor about the risks of LASIK surgery. There are many factors that can play a role in the success of the procedure, even factors like the temperature and humidity.
A new study just released shows that climate factors like temperature and humidity can affect LASIK surgery outcomes. Often, the patient has to come back in to get a touchup, to fine tune the vision correction.
