Abstract: Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs). Embodiments may include a shift of a diffractive order.

Abstract: Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for providing a range of vision. Chromatic aberrations may be reduced at near, distance, and intermediate vision.

Abstract: A ring halometer system configured to quantify dysphotopsias in a patient. The system includes a white screen and a first light source configured to emit a glare source from the white screen. The glare source is configured to form a veil of light visible to the patient when the glare source interacts with an optical surface of the eye of the patient. The system also includes a second light source configured to project a light ring with varying luminance concentric with the glare light source on the white screen, and a controller coupled to the second light source configured to adjust a size of the light ring. The system may also include an electronic device configured to determine a level of bothersomeness of the dysphotopsias experienced by the patient based on the size of the light ring.
