Hello,
I apologize if this topic has been covered, but I've searched and
haven't found any specific answers, so here goes.
I'm 44, healthy, and have worn soft contacts to correct for
myopia since I was 17. I'm right eye-dominant and for most of
my life could be corrected with conventional lenses to 20/15
acuity. Prior to my mid-30s my right eye always required less
magnification than my left.
Rather suddenly, and for unknown reasons, my right eye began
developing aberrations, first diagnosed when I was about 35.
Based on my own research, and a Lasik exam that I had 2 years
ago, I've determined that the aberrations have progressed to the
fourth, or fifth, order. I was turned away for the Lasik procedure
due to having "a too complex corneal topography".
The aberrations have stabilized, based on what I've observed
looking at lights in the dark, but the resulting loss of acuity is no
longer correctable beyond about 20/40 with standard, or
astigmatic, soft lenses. I haven't been fitted with RGPs, yet.
My left eye seems to be taking over (amblyopia?) and the right
side acuity seems to be getting worse.
Is anybody having success treating cases like mine with Lasik,
yet?
Thanks you very much in advance, and this forum is a GREAT
resource.
Matt

RGP contacts may help. Whatever you get with RGP is the best accuracy you can ever expect. Sorry to hear your only correctable to 20/40 now. I am also only correctable to that in the right eye, the left at 20/30 due to high order aberrations.

Matt,
It would appear that you have a disease or anomaly affecting your cornea. The possibilities are almost endless, but often can be well diagnosed. I very highly recommend - insist really - that you be evaluated by a cornea specialist. Preferably a corneal specialist at associated with a teaching university hospital as they tend to have more resources available than the average ophthalmologist.
Whatever has caused this situation needs to be diagnosed and, if possible, treated. Rigid gas permeable (RGP) contact lenses will undoubtedly help your vision quality, but you need to determine the underlying problem and not just treat the symptoms.

Glenn,
Thank you for your quick response.
Can you recommend a highly qualified corneal specialist in the
Denver area? Or advise on how I should go about finding one?
Cost is not a factor, as I would gladly re-mortgage my home to
have my vision back.
This has been the biggest source of concern and frustration in
my life for several years, now, and I haven't been able to get
what I consider adequate advice/action from my normal eye
doctor. Rather, his usual response is "you're older now and your
eyes ain't what they used to be. At least you still have one good
one left." This is unacceptable to me.
Again, thanks so much for your help.
Matt
