TH116603B - Intraocular lens (IOL) with variable chromatic aberration correction. - Google Patents

Abstract

Corrective lenses include a light filter element that can be used to filter visible light that has Wavelength less than 450nm At least In addition, the lens has a structural part. The first diffraction is adjusted to create a focal point for the visible light at the wavelength. The first range of more than 550 nm and to reduce the longitudinal chromatic aberration to less than one diopter. For visible light entering the first wavelength The lens is still The second diffraction structure Outside the first diffraction structure in the radial direction. It was adjusted to create a focal point for visible light at the second wavelength between 450 nm and 550nm. In addition, the second diffraction structure was also adjusted to reduce chromatic aberration. For visible light passing through the second wavelength to less than one Optometers, while allowing longitudinal chromatic aberrations in the first wavelength in quantities that Rather than the first diffraction structure too
