A scleral contact lens (SCL) can be defined as a lens that only rests on the sclera. Raised from the cornea and limbus, the total diameter must be greater than the horizontal visible iris diameter (HVID) and the extension of the limbus. Currently, the most commonly used lenses are scleral lenses with a diameter between 15.0 and 17.0 mm, the so-called mini-scleral lenses. The existing nomenclature of scleral lenses is based only on HVID and total diameter. It is therefore important to further differentiate smaller mini-sclera lenses from lager ones.
