Re: [ATM] Lasix and better viewing

["RodShea" <RodShea@comcast.net>]

Seems to be a lot of controversy about this.  I think a lot of it comes down 
to your night-time pupil diameter and the diameter of the area of the cornea 
that gets remodeled.  If the edge of the remodeled area is out of the light 
path, no problem.  If it is in the light path, you are at risk for a lot of 
refraction problems due to the edge itself.  Also, it seems that some of the 
halos and pointed star issues clear up as the cornea heals.

Someone I know who has a ?4 - 4.5 mm pupil does not see stars abnormally, 
and notes they have about 1 magnitude better night vision than before, when 
they used contacts.  Others report very different results.  YMMV.  Several 
Lasik machines/software can also correct a lot of astigmatism, others less 
so, best to ask a lot of questions.
