Toric intraocular lens: A literature review

Taiwan Journal of Ophthalmology, 2021
Abstract Toric intraocular lenses (IOLs) are universally recommended in cataract cases with preoperative corneal astigmatism ≥1.5 D. An optimal surgical outcome depends on careful patient selection, complete preoperative evaluation, accurate IOL power calculation, precise marking of the axis, meticulous intraoperative approach, and methodical

Rotational stability of modified toric intraocular lens

PLOS ONE, 2021
We evaluated the rotational stability of a new toric intraocular lens (IOL), HOYA XY-1 toric IOL that is an improved version of HOYA 355 toric IOL, with longer overall length (13.0 mm vs. 12.5 mm), shortened unfolding time, and texture processing of the surface of haptics.

Uso de lentes intraoculares tóricas no tratamento cirúrgico de astigmatismo [PDF]

, 2014
Correction of corneal astigmatism is a key element of cataract surgery, since post-surgical residual astigmatism can compromise the patient's uncorrected visual acuity.

Mesonic Chiral Rings in Calabi-Yau Cones from Field Theory [PDF]

, 2007
We study the half-BPS mesonic chiral ring of the N=1 superconformal quiver theories arising from N D3-branes stacked at Y^pq and L^abc Calabi-Yau conical singularities. We map each gauge invariant operator represented on the quiver as an irreducible loop

The Sasaki Join, Hamiltonian 2-forms, and Constant Scalar Curvature [PDF]

, 2015
We describe a general procedure for constructing new Sasaki metrics of constant scalar curvature from old ones. Explicitly, we begin with a regular Sasaki metric of constant scalar curvature on a 2n+1-dimensional compact manifold M and construct a ...

Toric implantable collamer lens for keratoconus

Indian Journal of Ophthalmology, 2013
Keratoconus is a progressive non-inflammatory thinning of the cornea that induces myopia and irregular astigmatism and decreases the quality of vision due to monocular diplopia, halos, or ghost images. Keratoconus patients unfit for corneal procedures and intolerant to refractive correction by spectacles or contact lenses have been implanted toric ...
