Abstract
A multi-wavelength wavefront system and method for measuring diffractive lenses. A system may include one or more light sources configured to emit a plurality of wavelengths of light for diffraction by a diffractive lens. A light sensor may be configured to receive the light that is diffracted by the diffractive intraocular lens. A processor may be configured to determine one or more of the plurality of wavelengths that have a peak diffraction efficiency for the diffractive intraocular lens based on the light received by the light sensor.
Claims20
A system for measuring diffractive lenses comprising:
- one or more light sources configured to emit a plurality of wavelengths of light for diffraction by a diffractive intraocular lens;
- a wavefront sensor configured to receive the light that is diffracted by the diffractive intraocular lens;
- and a processor configured to determine one or more of the plurality of wavelengths that have a peak diffraction efficiency for the diffractive intraocular lens based on the light received by the wavefront sensor.
A method comprising:
- applying a plurality of wavelengths of light to a diffractive intraocular lens;
- receiving light that is diffracted by the diffractive intraocular lens with a wavefront sensor;
- and determining one or more of the plurality of wavelengths of light that have a peak diffraction efficiency for the diffractive intraocular lens based on the light received by the wavefront sensor.
A method comprising:
- determining a wavefront aberration of a diffractive intraocular lens at a wavelength corresponding to a peak diffraction efficiency for the diffractive intraocular lens.
