TLDR
In this paper, the authors characterized a lens having a circular refractive power profile, which is defined as having a discrete power which is between the minimum and the maximum power of the lens.Abstract:
A lens having a circular refractive power profile is characterized in that, in at least one semi-meridian located between semi-meridians having the minimum and the maximum refractive power of the lens, it has a discrete refractive power which is between the minimum and the maximum refractive power of the lensread more

Aspheric toric lens designs
TL;DR: Aspheric toric lenses as discussed by the authors reduce the number of cylindrical axis locations required for stock keeping units in inventory by aspherizing the toric surface thereof, which can be used to enhance depth-of-focus.
Patent
Intra-ocular lens or contact lens exhibiting large depth of focus
TL;DR: In this paper, the authors proposed a refractive power profile for spherical and annular lens zones, which, at a given lens area, exhibit a depth of focus of a lens of considerably smaller area.
Patent
Contact or intraocular lens and method for its preparation
TL;DR: In this article, a toric lens is constructed with a smooth atoric aspect, where the optical path through the correcting portion of the lens corrects for both astigmatism and an axisymmetric aberration other than astigmatisms, there being no sudden surface discontinuity between the regions that provide the different corrections.
Patent
Astigmatic intraocular lens
TL;DR: In this article, an intraocular lens for correcting astigmatic ametropia was proposed, which has a toroidal refractive front face and a toroid refractive rear face, whose intersection curve is aspherical on at least one primary meridian.
