By combining two fundamentally different microscopy techniques, researchers can now measure the optical properties of a ...
A homeowner with rooftop solar panels turned to the internet for advice about why the panels' power output had declined ...
Although not a household scientific name like Albert Einstein or Isaac Newton, Indian mathematician Srinivasa Ramanujan—who tragically died in 1920 at the age of 32—was one of the greatest minds in ...
I am trying to calculate the effective index of a waveguide made out of a biaxial crystal for the waveguide and the substrate. From the anisotriopic example I am defining the substrate and waveguide ...
Patients who have a new type of lens implanted in their eyes during surgery for cataracts or to correct their eyesight have excellent or good vision over distances both near and far, and often no ...
Capsular tension rings can improve the prediction accuracy of new-generation IOLs in eyes with an axial length of 30 mm or longer, without affecting target refraction. Target refraction does not need ...
Please provide your email address to receive an email when new articles are posted on . Cyclopentolate and tropicamide had comparable refractive error values across ...
ABSTRACT: As cataract surgery progresses from “restoration of sight” to “refractive correction”, precise prediction of intraocular lens (IOL) power is critical for enhancing postoperative visual ...
