Efficient Rendering of Ocular Wavefront Aberrations using Tiled Point‐Spread Function Splatting

Monochromatic ocular wavefront aberrations in the awake-behaving cat

Measurement of wavefront aberrations in human eyes has become a reliable, quantitative way of assessing the optical impact of experimental and corrective ocular manipulations. Wavefront measures have also been performed in several other species, but never in cats, an animal model of choice for many ocular studies. Our goal in this study was to measure wavefront aberrations reliably in live, awa...

Wavefront Aberrations

Lower order aberrations are another way to describe refractive errors: myopia, hyperopia and astigmatism, correctible with glasses, contact lenses or refractive surgery. Lower order aberrations is a term used in wavefront technology to describe second-order Zernike polynomials. Second-order Zernike terms represent the conventional aberrations defocus (myopia, hyperopia and astigmatism). Lower o...

RAYS (Render As You See): Vision-Realistic Rendering Using Hartmann-Shack Wavefront Aberrations

RAYS (Render As You See) is a system for “vision-realistic rendering” which can simulate the vision of actual patients. Patient data is derived from sensors, called Hartmann-Shack devices, that capture the wavefront aberrations present in the patient’s entire optical pathway of a single point source of light in the retina. The input to RAYS is an image, corresponding depth information, and a wa...
