Epidemiology and Burden of Astigmatism: A Systematic Literature Review

Optometry and Vision Science, Volume 100, Issue 3, Page 218-231, March 2023., 2023
SIGNIFICANCE This is the first literature review to report the epidemiology, patient burden, and economic burden of astigmatism in the general adult population. The unmet needs of astigmatism patients with coexisting ocular conditions (cataract, glaucoma, dry eye, presbyopia, or macular degeneration) and risks associated with untreated astigmatism are ...

The Rank of Trifocal Grassmann Tensors [PDF]

SIAM Journal on Matrix Analysis and Applications, 2020
Grassmann tensors arise from classical problems of scene reconstruction in computer vision. Trifocal Grassmann tensors, related to three projections from a projective space of dimension k onto view-spaces of varying dimensions are studied in this work. A canonical form for the combined projection matrices is obtained.
