Bicentric Grinding

Bicentric grinding, also known as slab-off, is used to correct vertical imbalance. Typically, slab- off can be used to correct vertical imbalance over 1.5 diopters.

Bicentric grinding or slab-off is used to neutralize an unwanted prismatic effect caused by unequal refractive errors. Slab-off can be either conventional or reverse. Conventional slab-off is added to the front surface, lower part of the lens, and reverse slab-off is added to the rear surface, lower part of the lens.
