Standard soft-lens fittings are the most straightforward and typically carry the lowest fitting fee. Fittings for specialty lenses, including scleral lenses, hybrid lenses, and lenses for conditions such as keratoconus, an irregular corneal shape, involve more trial lenses, more imaging, and considerably more office time.
Specialty fittings often require advanced corneal mapping with a topographer and may take multiple appointments before the final lens parameters are confirmed. The additional complexity is reflected in a higher fee tier, which your provider will explain before any additional charges are applied.
