LASIK: Trip Report

[kevyk]

I think you'd be surprised how much the technology has advanced already. I had what is known as wavefront or custom LASIK. What this means is that they use an instrument that maps your eye very precisely using light waves.

This is a huge improvement over previous methods since it measures higher-order defects in the curvature of the eye which were not detected by the old method and which glasses don't fix. For instance, my vision had about a 0.5-diopter error due to higher-order defects. Haloes and blurring are much less common now, and achieving perfect-or-better vision is much more likely.
