Prescription: OD -2.50-.75 X 90, OS -8.50-3.50 X 45

Order the lens as specified
Order the prescription with a slab off
Order the lenses with a hi index lens

Explanation

Answer: B - In order to optimize this prescription for the patient’s best acuity you should order the prescription with a slab off.

To correct for vertical imbalance that occurs when the two eyes have such different powers of prescription, it is necessary to install a slab off on a lens to eliminate the prism effect created. The patient can adjust to the new prescription more comfortably and quickly.
