high rx
hi,
I need help. One of my customers brought her grandaughter in for her first pair of eyeglasses. The child has a presciption of OD plano-1.50 x 180 /os +12.75-1.00 x180 and an add only on os of a +1.50. What's the best lens possible that I can give her without her saying "egad, that's so thick and heavy". I don't want to lose her as a customer.
Ditto
recommend contact lenses. You didn't say how old this patient is.
I'm guessing she is amblyopic and a balance lens may due for her if glasses are her only option. Polycarb lenses also.Check with her Doctor if this is ok
Looks like she's a unilateral aphakic (left eye)that would explain the left reading add and Rx. I would assume she must be at least six years old otherwise the Rx would be a lot higher.
I'd agree a pair of contact lenses (or just a left contact lens to correct the anisometropia) and of course glasses to correct any residual prescription and include the left bifocal/varifocal lens.
I'm with everyone else on this. You just can't make a pair of glasses for a unilateral aphakic. Many years ago when implants were not an option and a period of time was involved between catarac removal in each eye. We used to have to frost the lens in whichever eye saw the poorest and correct the eye with the best acuity. Basicly leaving the patient one eyed until the second eye had surgery.
In high plus lenses you have high distortions as the eye turns to center, you have scotoma's, uneven magnifications which cannot be resolved in forward lenses. These are a problem even if the patient is bi-lateral and insoluable in unilateral situations.
Don't even bother making glasses for back up unless the unoperated eye has very poor acuity.

People!
Why +1.50 add???????????
If the person is aphakic shoud not the add be in 2.50-3.00 region??
Unless beeing a child changes things?
