AIM To investigate the independent factors associated with photic phenomena in patients implanted with refractive, rotationally asymmetric, multifocal intraocular lenses (MIOLs). METHODS Thirty-four eyes of 34 patients who underwent unilateral cataract surgery, followed by implantation of rotationally asymmetric MIOLs were included. Distance and near visual acuity outcomes, intraocular aberra...

PURPOSE To explore utilization of the coaxially sighted corneal light reflex (CSCLR) for centration during myopic photorefractive keratectomy (PRK) for patients with relatively high angle kappa (κ) values. METHODS Patients were stratified into two groups preoperatively, on the basis of angle κ values. Group A was composed of 166 eyes with an angle κ value <5°. Group B consisted of 182 eyes wi...

Equimolar mixtures of dodecyltrimethylammonium chloride (DTAC) and sodium octyl sulfonate (SOSo) show a vesicle phase at >99 wt % water and a single, fluid lamellar phase for water fractions below 80 wt %. This combination is consistent with the bilayer bending elasticity kappa approximately k(B)T and zero bilayer spontaneous curvature. Caillé line shape analysis of the small-angle X-ray scatte...

We investigate the shape of jet break in within-beam gamma-ray burst (GRB) optical afterglows for various lateral structure profiles. consider cases with and without spreading a range inclinations within core half-opening angle, $\theta_c$. fit model observed afterglow lightcurves smoothly-broken power-law function free-parameter $\kappa$ that describes sharpness break. find is sharper ($\kappa...

PURPOSE To compare grading of goniophotographic images and gonioscopy in assessing the iridocorneal angle. METHODS In a population-based, cross-sectional study, participants underwent gonioscopy and goniophotographic imaging during the same visit. The iridocorneal angle was classified as closed if the posterior trabecular meshwork could not be seen. A single masked observer graded the gonioph...

We report measurements of the thermal Hall effect in single crystals both pristine and isotopically substituted strontium titanate. discovered a 2 orders magnitude difference conductivity between ${\mathrm{SrTi}}^{16}{\mathrm{O}}_{3}$ $^{18}\mathrm{O}$-enriched ${\mathrm{SrTi}}^{18}{\mathrm{O}}_{3}$ samples. In most temperature ranges, (${\ensuremath{\kappa}}_{xy}$) is proportional to longitudi...
