For many decades only a few formulas have been available to calculate the intraocular lens (IOL) power for patients undergoing cataract surgery: the Haigis, Hoffer Q, Holladay 1 and 2 and SRK/T. In recent years, several new formulas for IOL power calculation have been introduced with the aim of improving the accuracy of refraction prediction in eye...
We demonstrate an alignment-tolerant backside coupling interface in the O-band for silicon photonics by generating an optimized through-substrate (downward) directionality beam from a TE-mode grating coupler and hybrid integrating the chip with backside silicon microlenses to achieve expanded beam collimation. The key advantage of using such an exp...
We aimed to evaluate the efficacy and utility of loupes for ENT on-calls. We conducted a 2 month prospective clinical study using loupes during on-calls. We examined patients twice, with and without loupes and compared visibility and diagnostic ease. We used the loupes in a total of 71 patients for a variety of ENT emergencies. We found that visibi...

BackgroundMyopia is a common visual disorder with increasing prevalence. Halting progression of myopia is critical, as high myopia can be complicated by a number of vision-compromising conditions.MethodsLiterature search was conducted in the following databases: Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica data...
Two stages optical concentrators for concentrated photovoltaic (CPV) are studied both experimentally and theoretically. They are composed of a Fresnel lens made of PMMA and coupled to two different secondary optical elements (SOEs) types: a pyramid and a cone made of fused silica. Results, in terms of optical efficiency and acceptance angle, show t...

Blocking a selected wavelength range from the light spectrum can have multiple benefits. Ultra-violet (UV) radiation is detrimental to the retina, necessitating its blocking through sunglasses and contact lenses. The near-visible light also has enough energy to cause damage but, is typically not blocked by commercial lenses. Filtering light can als...
Context: Since autonomous vehicles operate in an open context, their software components, including data-driven ones, have to reliably process inputs (e.g., obtained by cameras) in order to make safe decisions. A key challenge when providing reliable data-driven components is insufficient training data, which could lead to wrong interpretation of t...
Light field technology, which emerged as a solution to the increasing demands of visually immersive experience, has shown its extraordinary potential for scene content representation and reconstruction. Unlike conventional photography that maps the 3D scenery onto a 2D plane by a projective transformation, light field preserves both the spatial and...
