I've been wearing a Fluorperm 30 RGP lens for several months now. The
vision & comfort is good but after several hours wear the lens tends to
feel dry and fog up. My optician says the lens is good fitting but the
tears are evaporating more quickly and causing slight 6 / 9 staining. I
have had a punctal plug fitted which appears to have helped somewhat and
my optician is making enquiries to see about a better wetability
material lens. In the meantime I thought I'd ask here for any opinions
on what is considered a good lens for dry eyes. Thanks.

Two issues relating to RGP lens dryness and fogging: material wetting
and lens care products. The Fluoroperm 30 that you have is one of the
better material choices. Others include Menicon Z, Optimum, Alberta S,
Hydro 2 and others, in no particular order. All of these materials have
low wetting angles.

The next issue is lens care. The product you use must be compatible with
the lens material and must be used correctly. If the surface is not
clean when you start off in the morning, it surely wont stay comfortable
and clear for very long. Try using a cotton swab with cleaning solution
to get the inside surface of the lens clean. Change lens care products
(ask your practitioner) and always use the product-mate in the cleaning,
storage and wetting products. Don't mix and match. Make sure you lens
care is ultra clean. Clean it. Replace it monthly.

Or, of course, you might be one of those people for whom RGP lenses is
not the best choice in contact lenses.

Thank you Larry, I will pass that info on to my optician. Must admit
the Fluoroperm is far better than the previous Boston lens I tried -
can't remember exactly which make of Boston it was but it fogged up
almost immediately. At least with the Fluoroperm I can go quite a few
hours (and sometimes all day) before the dryness and fog occurs. If any
of the others you mention will help then I will be very happy.

I've tried various solutions and found the one that works best for me is
Alcon's Unique-PH with a drop of Supraclens added to the case. I'm also
trying out Clens100 drops and they do appear to be pretty good. Some of
the other drops I tried were thicker viscosity and seemed to gunk up the
eye and make the fogging worse.
Thanks for that.
