26. Bicentric grinding is a process in which a lens has a prismatic vertical imbalance. This can prevent a person from properly reading. This is a common condition with bifocals. A special grinding technique, called bicentric cutting, can correct this. A slab off procedure uses a dummy lens that is cemented to the front surface of the lens.
