My LASIK posts have been ridiculously popular, considering this is a .NET and Programming Blog. That being said, there were a few blogs that mentioned my surgery and I thought it would be useful for me spend some time in Photoshop and explain to you EXACTLY what I saw, and EXACTLY what I see now.
Here's before, this is -9.25 diopters (roughly 20/1600 for me) and what I saw without glasses for ~20 years. I adjusted this photo in Photoshop to show represent what I saw before as accurately as possible.
Here's after. I'm now at LEAST 20/20 (I'll be officially measured this Friday, one month after my operation. I suspect I'll be 20/15. Just a hunch.
I adjusted this after picture to show you exactly what I see now. Note the slight “motion” blur over the lights. Note the darkness of the background and the bright contrast of the foreground.
Not to bad for a Windows 98 machine. One thing to note also. While it's totally reasonable to worry about this operation, and most folks are concerned that they might never seen well again, I thought it was a reasonable risk. It IS VERY possible to have side-effects that will result in a loss of best corrected vision. There's about a 0.04 percent chance using my doctor's stats. The problem with stats that compare success with failure is that someone has to fail. I feel really bad for folks that are in that 0.04 percent bucket - having surgery is inherently dangerous.
That said, I'm happy with the result - more every day - and I will enjoy the next 10 years of vision...before I have to get bi-focals!
