Monte Carlo simulation of expected outcomes with the AcrySof® toric intraocular lens [PDF]
BMC Ophthalmology, 2008 Background To use a Monte Carlo simulation to predict postoperative results with the AcrySof® Toric lens, evaluating the likelihood of over- or under-correction using various toric lens selection criteria.

Evaluation of corneal biomechanical properties in spherical and toric soft contact lens wear
Medical Journal of Dr. D.Y. Patil Vidyapeeth, 2022 Purpose: Corneal hysteresis (CH) and corneal resistance factor was found to be less for patient wearing toric contact lens as compared to soft spherical CH was calculated as the difference in air pressures between force-in applanation (P1) and force-out ...

Repeatability of in-vitro optical quality measurements of intraocular lenses with a deflectometry technique effect of the toricity [PDF]
International Journal of Ophthalmology, 2018 AIM: To evaluate the repeatability of an optical device for measuring the Zernike coefficients of toric intraocular lenses (IOLs) and assess whether its toricity has any impact in its repeatability.

Journal of Medical Case Reports, 2012 Introduction We report the case of a patient in whom simultaneous toric phakic intraocular lens removal and phacoemulsification with toric intraocular lens implantation were beneficial for reducing pre-existing astigmatism and acquiring good visual ...

Near visual function measured with a novel tablet application in patients with astigmatism
Clinical and Experimental Optometry, EarlyView., 2020 Clinical relevance While the clinical focus of performance metrics is traditionally based on visual acuity, research from the field of visual impairment has demonstrated that metrics such as reading speed and critical print size correlate much more strongly with subjective patient reported outcomes and assessed ability in real‐world tasks.

Journal of Education, Health and Sport, 2021 At the same time, phacoemulsification of cataracts remains the most popular surgery. But the problem among phacosurgeons is the correction of existing corneal astigmatism. According to studies, about 30% of the world's population have corneal astigmatism

Correction of High Corneal Astigmatism during Cataract Surgery
Oftalʹmologiâ, 2019 Patients, who need cataract surgical treatment, often fail to achieve a high uncorrected visual acuity after surgery due to the concomitant astigmatism involved.

Large N Duality, Lens Spaces and the Chern-Simons Matrix Model [PDF]
, 2003 We demonsrate that the spectral curve of the matrix model for Chern-Simons theory on the Lens space S^{3}/\ZZ_p is precisely the Riemann surface which appears in the mirror to the blownup, orbifolded conifold.

, 2007 We propose a complete, new formalism to compute unambiguously B-model open and closed amplitudes in local Calabi-Yau geometries, including the mirrors of toric manifolds. The formalism is based on the recursive solution of matrix models recently proposed
