I doubt you'll notice that much more change after a few more months.
The change of iris color, in those of my patients who went to darker
brown, generally takes a few years in my opinion.   Brown eyes aren't
so bad...I've had mine for almost 41 years.  More important to keep
them seeing.  I wouldn't care if my eyes looked purple, as long as I
could see my daughters' beautiful faces each morning.  Let's keep
things in perspective, Ann.
   By the way, is your doc switching you to something else?  If so,
what will you be using?  Keep in mind that, pound for pound, Lumigan is
the best drop out there at lowering IOP.
Take care,
Dr. Cohn
