Advice Request: Changes after Corneal Ulcer

Dear Ladies and Gentlemen:

I hope you can provide some advice, and thank you, in advance...

My age is 46. Some six years ago, I suffered a corneal ulcer in my right eye
and my vision has not been able to be corrected to 20/20 since then (this
particularly sucks, as I had been a commercial pilot until then).

Prior to the ulcer, I had single vision correction (both for glasses, as
well as contacts):

-1.75 Left
-0.75 Right

Shortly after the ulcer healed, the ophthalmologist adjusted my prescription
accordingly:

-1.75 Left
0.00 Right

After lengthy refractions, it was determined that my right eye saw best with
no power, either way. I was comfortable with my contacts and glasses, with
that prescription.

Now, well into my 40's, I recently went for a contact lens-exam and was
given a +2.25 for my right eye -- it has been great! I seldom have to wear
reading-glasses.

Two months ago, I decided to get new eye-glass frames. This is when my
problems really began: my new eyeglasses are polycarb, and very, very
"milky."

The optometrist scoffed at my inquiry to make the right lens a +2.25, to
mimic my contact lens prescription. He said that a one-lens contact
"farsighted" prescription cannot be carried over to one lens in a pair of
glasses.

Please: is this true???

If I'm seeing well with -1.75 and +2.25 while wearing contacts, why couldn't
I have glasses built with those respective powers?

My insurance company is willing to "allow" me to swap the polycarbs for
Trivex -- will this help at all?

And what about Crizal Alize? And edge-polishing?

Sorry for the myriad of questions.

Quite confused,
Tammy

Tammy, you have 4 diopters of anisometropia (ie. refractive
difference between your 2 eyes) when you are wearing your
monovision contact lenses.  While this difference (between
your two eyes) works with contact lenses, it does not
work as well with glasses (image size differences). I
guess you could try it if the doc agrees to the rx but it's
more than a good possibility than you would have some
difficulty getting adapted to it. I have fit patients in
"monovision" glasses (but it's not common) but the
difference is usually much less than in your situation.

As far as the polycarbs, just about any type of lens
(Crizals/Trivex) would give you better clarity).

Hope this helps.

Dear Dr. Frank,

Thank you for your response to my inquiry! Are you saying that you HAVE had
positive feedback from those who asked for "monovision" glasses?

I think that I read somewhere on this newsgroup that Crizal's Alize is not
available to Trivex material. Am really curious as to that, since, after
speaking with my insurer, I was led to believe that Crizal Alize is an
option that they would cover. (But do they realize that Crizal Alize might
not be available as a coating on Trivex lenses?)

Again, thanks in advance, to all!

I have a few patients doing both monovision with cl's and glasses but
they are in the minority and with much less than the 4 diopters
of difference than what you have. Without actually trying it for you
I couldn't predict how well you would do.

Tammy, even a regular cr-39 (regular plastic) would be suitable
for you. I don't have the information in front of me so I'm not sure
whether the Alize is available on Tivex. Your optician could tell
you for sure.  Best of luck.

Thanks again, Dr. Frank, for your comments!

My optometrist said he suggests polycarbs for semi-rimless frames, as the
lens thickness-variance between the two sides would not be as noticeable.
Would the cr-39 lenses (-2.00 [left] and 0.00 [right]) be so awkward-looking
together, in a rimless frame?

BTW, I made it very clear to my optometrist that vision acuity was of
import; that a negligible difference in thickness between the two lenses
mattered far less, as I would be wearing the glasses at home, at night,
primarily.

Thank you so much for your perceptiveness and professionalism!

Best,
Tammy
