Spherical Aberration Customization to Extend the Depth of Focus With a Clinical Adaptive Optics Visual Simulator.

Journal of refractive surgery, 2020
PURPOSE To evaluate the use of the VAO adaptive optics visual simulator (Voptica SL, Murcia, Spain) for customization of spherical aberration to increase depth of focus. METHODS Through-focus visual acuity with both high- and low-contrast letters from +

General formula to design a freeform singlet free of spherical aberration and astigmatism.

Applied Optics, 2019
In this paper, an analytical closed-form formula for the design of freeform lenses free of spherical aberration and astigmatism is presented. Given the equation of the freeform input surface, the formula gives the equation of the second surface to ...

Age-Related Changes in Corneal Spherical Aberration.

Journal of refractive surgery, 2018
PURPOSE To analyze the age-related changes in corneal spherical aberration (CSA) and higher order aberrations (HOAs) and to develop a novel model to estimate the change in CSA with age.

Calculation model of dense spot pattern multi-pass cells based on a spherical mirror aberration.

Optics Letters, 2019
We report a novel calculation model for dense spot pattern multi-pass cells consisting of two common identical spherical mirrors. A modified ABCD matrix without the paraxial approximation was developed to describe the ray propagation between two ...
