minus over-correction vs plus under-correction

[JackRoanaoke]

Hello everyone,

I am corresponding with an OD over email. He said:

"I would NOT like her to have -1.00 lenses with -1.50 astigmatism... I am OK with her having plus undercorrection to plano -1.50 in both eyes...
...
When the PO suggests minus lens over-correction or surgery... that is the time to make the trip to see me. "

Can you please explain

minus over-correction
plus under-correction

Thank you.

History:

My 5 year old daughter has intermittent strabismus for near and constant strabismus for distance.

Her prescription from 2013 when she first saw a pediatric opthalmologist(PO) is:

OD = +0.50 | +1.50 x 90
OS = +0.25 | +1.50 x 75

but he had advised

OD = 0.00 | +1.50 x 90
OS = 0.00 | +1.50 x 75

Notice, no spherical power.

A different PO had prescribed:
OD = -3.00 | +1.50 x 90
OS = -3.00 | +1.50 x 80

which I believe is equivalent to:

OD = -1.50 | -1.50 x 0
OS = -1.50 | -1.50 x 170

Now, a new PO has prescribed:
OD = 0.00 | -1.50 x 0
OS = 0.00 | -1.50 x 165

I believe that last 2 prescriptions have minus over-correction.

Now, I am talking to a new OD by email. What does the OD mean by:

"I would NOT like her to have -1.00 lenses with -1.50 astigmatism... I am OK with her having plus undercorrection to plano -1.50 in both eyes..."

Thank you.

Need more info. Backstory.

This sounds like a conversation the OD is having with a surgeon's office? Where does a lens manufacturer fall into this spectrum of care?

@peyes, I added my daughter's history in my original post.

Hey, this isn't appropriate. We don't manage individual's kid's cases online, here, do we?

Nope. Violation of rules. Time to close this thread

Dare we say consumer?
