Toric Geometry [PDF]

, 2019
Toric geometry is a subfield of algebraic geometry with rich interactions with geometric combinatorics, and many other fields of mathematics. This workshop brought together a broad range of mathematicians interested in toric matters, and their ...

Newer Intraocular Lenses in Present Day Cataract Surgery

Delhi Journal of Ophthalmology, 2013
Intraocular lens (IOL) technology has evolved dramatically in recent years with various premium IOLs improving the visual outcome. Toric IOLs with toricity on their posterior surface are able to correct astigmatism but the results depend on the correct ...

Quantum (Non-commutative) Toric Geometry: Foundations [PDF]

, 2020
In this paper, we will introduce Quantum Toric Varieties which are (non-commutative) generalizations of ordinary toric varieties where all the tori of the classical theory are replaced by quantum tori.

Rotational stability of toric intraocular lenses by lens model and haptic design: systematic review and single-arm meta-analysis

Journal of cataract and refractive surgery
In a meta-analysis of 51 published studies including 4863 eyes, the pooled mean absolute postoperative rotation of all toric IOLs was 2.36 degrees (95% CI, 2.08-2.64).

Toric Quasifolds [PDF]

, 2022
Toric quasifolds are highly singular spaces that were first introduced in order to address, from the symplectic viewpoint, the longstanding open problem of extending the classical constructions of toric geometry to those simple convex polytopes that are ...

Toric Promotion [PDF]

, 2022
We introduce toric promotion as a cyclic analogue of Sch\"utzenberger's promotion operator. Toric promotion acts on the set of labelings of a graph $G$.

Predictive accuracy of Barrett TK toric calculator compared to measured posterior corneal astigmatism using Pentacam in toric IOL power calculation

Indian Journal of Ophthalmology
Purpose: To compare the predictive accuracy of Barrett total keratometry (Barrett TK) toric calculator with the measured posterior corneal astigmatism (PCA) by using Pentacam in toric intraocular lens (IOL) power calculation.
