Single microstructure lens, systems and methods

摘要

Systems and methods for providing enhanced image quality across a wide and extended range of foci encompass vision treatment techniques and ophthalmic lenses such as contact lenses and intraocular lenses (IOLs). Exemplary IOL optics can include a circular surface structure which acts as a diffractive or phase shifting profile. In some cases, a single ring IOL includes an anterior face and a posterior face, where a profile can be imposed on the anterior or posterior surface or face. The profile can have an inner portion such as a microstructure or central echelette, and an outer portion. Between the inner portion and the outer portion, there may be a transition zone that connects the inner and outer portions.

主权项

1. A method of designing an ophthalmic lens comprising only one isolated echelette, the method comprising utilizing pupil size measurements and based on the measurements determining the size of the one isolated echelette to impose on an anterior face or an opposing posterior face of the ophthalmic lens.
