A new algorithm offers accurate IOL calculations in eyes undergoing cataract removal after previous laser refractive surgery, according to a study. Wolfgang Haigis, MS, PhD, devised the Haigis-L ...

An IOL power calculation formula based on optical coherence tomography equaled conventional methods in cataract patients without previous laser vision correction, a study showed. "This new formula is ...

CRAIC Technologies, Inc. joins with Laboratory Imaging, s.r.o., a leading specialist in imaging software solutions for microscopy, to introduce rIQ™ : the intelligent solution for the analysis of ...

The refractive index of a material defines the angle through which light is bent when it travels between a material and the vacuum. Ordinary materials such as glass have refractive indices between one ...

Researchers in Korea have created a new metamaterial with the most extreme positive index of refraction yet – a whopping 38.6. The metamaterial operates at terahertz frequencies and the team believes ...
