Targeting a postoperative spherical aberration of 0.1 µm for patients, rather than using the same aspheric IOL with fixed spherical aberration correction for all patients, is the best way to achieve ...
Abstract: The effect of spherical aberration on the radius of image beam waist in the design of laser optical system is discussed in detail, and the relationship between the spherical aberration and ...
Edmund Optics has introduced TechSpec spherical aberrationcompensation plates optimized for use in collimated light with small fields ofview. Leveraging a precision BK7 substrate, these ...
Thirty patients were randomised to receive one of six lens implants including three aspheric lenses and their spherical counterparts. Pre and postoperative testing was carried out including visual ...
Applying aspheric treatments to cataract and refractive surgery procedures can significantly reduce spherical aberration and the consequent effects of glare and haloes, improving postoperative visual ...
Considering patients' spherical aberrations may allow a better contact lens-wearing experience for patients with presbyopia. Wearing multifocal contact lenses alters spherical aberration and visual ...
The history of optics dates back more than 2000 years, as the legend “Archimedes, an ancient Greek scientist, has collected sunlight with a concave mirror and burned an enemy ship”. It is reported ...
BERKELEY, CA -- TEAM 0.5, the world's most powerful transmission electron microscope -- capable of producing images with half-angstrom resolution (half a ten-billionth of a meter), less than the ...
