PURPOSE To evaluate the change of accommodation-convergence parameters after implantation of Artisan phakic intraocular lens (PIOL). METHODS Prospective study for the patients with the Artisan PIOL implantation was performed. A total of 37 patients (3 males and 34 females) enrolled the study. Preoperatively, convergence amplitude, the stimulus accommodative convergence per unit of accommodati...

The purpose of this paper and its sequel [GS11b] is to introduce and develop a theory of toric stacks which encompasses and extends the notions of toric stacks defined in [Laf02, BCS05, FMN10, Iwa09, Sat12, Tyo12], as well as classical toric varieties. In this paper, we define a toric stack as the stack quotient of a toric variety by a subgroup of its torus (we also define a generically stacky ...

PURPOSE To analyze intraocular lens (IOL) orientation data from an online toric back-calculator (astigmatismfix.com) for determining if differences were apparent by lens type. METHODS A retrospective review of astigmatismfix.com toric back-calculations that included IOL identification and intended orientation axis. RESULTS Of 12,812 total validated calculation records, 8,229 included intend...

1 Toric varieties are by now familiar objects in algebraic geometry, but this note is concerned with variations on that theme, and I will try to be careful about terminology. A toric variety is a kind of orbifold, and hence has mild singularities, but I will use the term toric manifold in the sense of Davis and Januszkiewicz [4]; a smooth toric variety thus has an underlying toric manifold, but...

In this paper, we will show how these properties of residues can be generalized to an arbitrary projective toric variety. The paper is organized into six sections as follows. In §1, we define the cohomology class [ωg] ∈ H(P,ΩPn), and then §2 generalizes this to define toric residues in terms of a toric analog of the Trace Property. We recall some commutative algebra associated with toric variet...

Extending work of Bielawski-Dancer [3] and Konno [12], we develop a theory of toric hyperkähler varieties, which involves toric geometry, matroid theory and convex polyhedra. The framework is a detailed study of semi-projective toric varieties, meaning GIT quotients of affine spaces by torus actions, and specifically, of Lawrence toric varieties, meaning GIT quotients of even-dimensional affine...

Dropping separatedness in the definition of a toric variety, one obtains the more general notion of a toric prevariety. Toric prevarieties occur as ambient spaces in algebraic geometry and moreover they appear naturally as intermediate steps in quotient constructions. We first provide a complete description of the category of toric prevarieties in terms of convex–geometrical data, so–called sys...

purpose: to evaluate the efficacy and safety of primary aphakic artisan–verysise intraocular lens (iol) implantation during complicated cataract surgery. methods: the study is a retrospective analysis of 49 eyes that underwent primary aphakic artisan iol implantation for complicated cataract surgery. compiled data included demographic information, visual outcomes and complications. pre- and pos...

We treat equivariant completions of toric contraction morphisms as an application of the toric Mori theory. For this purpose, we generalize the toric Mori theory for non-Q-factorial toric varieties. So, our theory seems to be quite different from Reid’s original combinatorial toric Mori theory. We also explain various examples of non-Q-factorial contractions, which imply that the Q-factoriality...
