Power calculator for an ophthalmic apparatus with corrective meridians having extended tolerance or operation band
Last updated:
Abstract:
An IOL calculator is disclosed to determine the spherical equivalent (SE) and cylinder power for toric lenses and ophthalmic apparatuses having the extended band of operational meridian, such as the rotational extended tolerant toric intraocular lens. The IOL calculator may also be used for an extended rotational tolerant toric intraocular lens, an extended depth of field intraocular lens, an extended depth of field toric intraocular lens, an extended range of vision intraocular lens, and an extended range of vision toric intraocular lens.
