The wavefront of the emerging beam carries refractive information relating to the eye’s optics. For example, if the eye is emmetropic (i.e., the eye’s optics are without refractive error), the ...

NASHVILLE, Tenn. — Wave-guided optics application technology may now help patients with keratoconus, according to a speaker at Optometry’s Meeting. “We know a lot of our irregular cornea patients ...

English Education is published by CEE, the Conference on English Education (a constituent organization of the National Council of Teachers of English), and serves as a forum for discussion of issues ...

One of the promising new applications using the femtosecond laser in refractive surgery is the IntraCor procedure, [5,25] which is based on a controlled biomechanical manipulation. In this procedure, ...

Physicists at Harvard University in the US have built a silicon waveguide that exhibits a refractive index of, or close to, zero when operating at near-infrared telecom wavelengths. The waveguide can ...
