Toric splittings

The toric ideal $I_A$ is splittable if it has a toric splitting; namely, if there exist toric ideals $I_{A_1}, I_{A_2}$ such that $I_A=I_{A_1}+I_{A_2}$ and $I_{A_i}\not =I_{A}$ for all $1 \leq i \leq 2$.

Associations between anterior segment parameters and rotational stability of a plate-haptic toric intraocular lens

Journal of cataract and refractive surgery, 2021
Plate-haptic toric IOLs rotated more in eyes with larger white-to-white distance and longer anterior segment length. Therefore, toric IOL implantation should be performed with caution in eyes with these characteristics.

Toric Vaisman manifolds

Journal of Geometry and Physics, 2016
Vaisman manifolds are strongly related to Kahler and Sasaki geometry. In this paper we introduce toric Vaisman structures and show that this relationship still holds in the toric context.
