Looking at laser spot

I've had LASIK and I see starbursts on bright objects. Now, when I look at a
spot created by a laser pointer, I see a very clear starburst. When I move
(or rotate) my head, the pattern will slightly change and I believe I can
"browse" the optics in my eye - how it shapes the image in different angles.
As an observation, the formation of the starburst itself stays the same (of
course when pupil size is changed the size of the starburst is changed
accordingly) - only the details within the starburst are changing.

This experiment can not be made with normal light. Is someone able to
explain why exactly it works with laser only and how the rays are being
refracted in the eye (what is the angle-dependent changing layer I see)?
Also please tell me if there are better forums for asking these type of
questions.

I didn't find the answer here:
http://www.answers.com/topic/laser-applications but it's a nice page about
lasers.
