DrG (or anyone besides Ace):

I went to my new eye doc today for my annual checkup, and to get a
second opinion on my RGP fit.  I mentioned Macrolens, and he said he
had fit them quite a bit a few years ago, but nobody could really wear
them for more than four hours or so due to lack of sufficient tears and
oxygen under the large lens.  People really liked the vision but just
couldn't wear them all day.

Was this your experience, and has something changed within the last few
years to improve this?  When I asked before, you didn't really indicate
any downside.

No.  That has not been my experience.  As with any contact lens, YMMV.
I agree that tear circulation under the lens can be an issue, as it can
be with any lens.  My assistant wears Macrolenses, and my wife also
wears them when she chooses to wear contact lenses.

Most of the Macrolenses I fit are for special cases, i.e. post-LASIK,
keratoconus, post-corneal transplant, etc.

Why is that?  There must be _some_ downside you are avoiding by
defaulting to the small RGPs.  Comfort, cost, quality of vision ...
something.  Do your wife and assistant wear them simply because they
like them, or because they are special cases?

Thanks.

My wife wore corneal RGP lenses for much of her life.  Her eyes became
dry, red, etc.  She also has astigmatism.  Toric softs didn't work for
her.  Macrolenses did.  My assistant had LASIK in 1998.  Now she sees
one image instead of multiple images.  She has to remove the lenses
during the day to rinse them, but it's worth it to her.

There are many nuances to fitting contact lenses that come only from
many years of experience and cannot be explained in one paragraph.
Macrolenses can be complex to fit.  I am one of those who leans towards
disposable soft lenses for simple prescriptions.  In some situations,
Macrolenses are a problem solver.  For specialty fits, I can charge
enough of a fee to cover the increased chair time and costs associated
with fitting the Macrolens.

My advice is to go to the C&H Contacts website and find a fitter in
your area who will trial fit you.  Unfortunately, you may have to shell
out some bucks to try them.
