Augmented vision by 2050? Nope.. it's here now!
Monday, September 14, 2009 at 2:40AM Recently I've been debating the idea of laser corrective eye surgery, I like the idea of using technology to modify our bodies and return them to a more functional state but as you may or may not know some forms of Laser eye surgery can be quite invasive.
In classical laser eye surgery, a flap is cut around your eye lens, which is then flipped open and the laser flashes and burns tissue on the cornea to correct imperfections within your eye. This does look very invasive, for those that are a little squeamish you might want to avoid pressing play but it is fascinating how effective the laser is at correcting imperfections.
What's even more fascinating is that newer forms of laser eye surgery (using customised wavescans of the inside of your eye) may be able to improve your sight more so than conventional glasses or contacts by correcting Higher-order aberrations that can improve night vision, quality of vision and might just be able to improve your vision beyond 20/20. The idea of creating "super vision" with laser eye surgery isn't new but now it's a very real prospect with improved all laser eye surgery, the theoretical limit of foveal acuity would be 20/12 for a small pupil and up to 20/5 for a dilated pupil. Super vision anyone?

Hey Ryan, good piece.
I too like the eye-dea of super eyesight. When I worked with an opthalmology co over in the UK they told me that they didn't know of a single ophthalmologist who'd had laser treatment done (this was a few years ago).... mmm
Two reasons why I wouldn't do laser eye treatment as yet.
1) Laser eye treatment has the same (unneccessary) risk issues as with any elective surgery done for cosmetic reasons.
2) There hasn't been enough long term studies on laser eye surgery. This is reflected in the tiny percentage of eye professionals that have embarked on this treatment.
In particular I'm not sure what would happen if (a lot later granted) you had a cataract. Currently to treat that they insert an artificial lens into your cornea.
