After my miraculous and beloved Lasik procedure, I have noticed that I see halos around light sources, especially in low-light situations. This is a very minor and common side-effect of Lasik, and generally recedes or disappears as the eyes heal, although there is no guarantee. I wanted some kind of guideline as to when or if to start worrying about the halos not receding, and it looks like about a month or so is usually long enough for them to fade. However, while researching the halos I got interested in what Lasik is exactly, and ended up on Wikipedia. It turns out that Lasik is performed with a device called an excimer laser, and check out how awesome they are:

“Rather than burning or cutting material, the excimer laser adds enough energy to disrupt the molecular bonds of the surface tissue, which effectively disintegrates into the air in a tightly controlled manner through ablation rather than burning. Thus excimer lasers have the useful property that they can remove exceptionally fine layers of surface material with almost no heating or change to the remainder of the material which is left intact.”

Disintegration is cool.
