To demonstrate the results of the ray tracing-type aberrometer in measuring spherical aberration (SA) in pseudophakic eyes with monofocal intraocular lens (IOL), aspheric monofocal IOL, or aspheric ...

Not an aberration: schematic drawing of the metalens (left), which is made of tiny titanium waveguides. The drawing on the right is of a single waveguide. (Courtesy Boubacar Kanté) A new type of ...

THE steeply curved surface of the field lens of a Kellner-type eyepiece usually introduces considerable spherical aberration of the principal rays. Frequently, this aberration cannot be corrected ...

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 ...

Higher-order aberrations were corrected by around 75% in eyes with keratoconus fitted with Zenlens Chroma HOA, according to data presented at the Global Specialty Lens Symposium.“Patients with ...
