In highschool I thought I wanted to go into biomedical engineering.  
After spending a semester desigining a hinge, I decided that for a poor 
math student like me engineering was not likely to fire my imagination.  
Still, I kept up with advances there for some time. One of the most 
fascinating procedures I read about was an operation where they removed 
the lense of your eye, froze it, mounted it in a tiny lathe and turned 
the lense to correct the shape, thinning it at  the same time to 
increase its flexibility.  It was then put back in your eye.  I think 
lasic killed the research on that procedure since lasic was simpler and 
thus more commercially viable.  Maybe one day.
