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 ...
Aspheric IOL implantation markedly reduced spherical aberration and vertical coma, but the decrease in aberrations may have correlated with an undesirable reduction in depth of focus. “The results in ...
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 ...
Total, corneal, and internal aberrations were measured using ray-tracing technology in 23 eyes implanted with aspheric (Tecnis ZA9003) IOLs, and in 25 eyes implanted with spherical (AcrySof SA60AT) ...
Camera lenses are often described as being 'aspherical', but what does it mean, and is it the only way to design a lens? A lot of lenses are spherical, though. What we mean by “spherical” is usually ...
Apochromatic (APO): A lens group designed to correct chromatic aberrations for three wavelengths (usually red, green, and blue) rather than just one or two. Aspheric: A lens element with a ...
Knight Optical can offer Custom Moulded Aspheric Lenses for use with Laser Diode Collimators. Aspheric lens surfaces are used to correct spherical aberration (where the converging light from a lens ...
One of the oldest problems in optics has been solved. Rafael Gonzalez from Mexico's Tecnologico de Monterrey has come up with an almost comically dense equation that can be used to almost completely ...
