For adult eye alignment, are small prisms in the lenses a treatment solution when eye surgery didn’t help?
Prisms are excellent optical means of reorienting the incoming visual information to account for small offsets in alignment. In this way prisms can be excellent choices for some adult patients with small residual deviations after surgery. In addition, prisms can be used to manage a small binocular misalignment even without the use of surgery. Larger prisms are associated with more blur of the image and increased technical ability to fabricate. As such they are used less often, many times on a temporary basis to eliminate double vision.
