LASERS!
November 9, 2007Several days ago I noticed that I was having trouble iwth my peripheral vision which happens sometimes before the onset of a migraine headache but the migraine never came and the vision problem remained. Alice took me to an eye specialist in Dalian and the diagnosis was that I had a hole in my retina that need to be sealed by using a laser. The procedure took only several minutes and I need to check in 3 weeks how the healing is going. It is likely that the perhiperhal vision loss might be permanent but it isn’t severe. Sealing the hole was the method of preventing further problems which could have been severe had we not been so on the ball.
Being blessed with some of the worst eye sight a human being can have I am now very very greatful for the presence of Lasers and their ability to repair things such as this. By the way laser is an acronym for “Light Amplification by Stimulated Emission of Radiation”. We use lasers in playing DVD’s and CD’s, scanning bar codes at supermarkets and for many medical applications like mole removal and apparently fixing retinal holes.
The upside is that I won’t go blind. Yay! The downside is no Shenyang hockey trip this weekend for me and no sports for 3 weeks. A small price to pay for vision I guess.
Thank you Albert Einstein for investigating photons and the properties of light that eventually led to the development of lasers.
