At what level of anisometropia do symptoms typically appear?
2 diopters of prescription difference between the two eyes.
What is the solution to anisometropia greater than 2.0D in the 90 degree axis when the patient needs a bifocal?
Slab-off. Contact lenses, separate reading and distance glasses, or a high places bifocal segment are other less frequent alternatives to slab-offs.
What four things can you do to minimize the effects of anisometropia in any patient, whether or not the patient needs a bifocal?
Equalize the center thickness as best as possible, equalize the base curve as best as possible, steer the patient to a small frame, and order slab-off if the patient is able to wear a bifocal.
When slab-off is prescribed, on which lens is it applied?
Why might cataract surgery make macular degeneration symptoms more noticeable?
