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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
