A rigorous model, CASIM (corneal ablation simulator), has been developed to model the ablation profile design, the shot-by-shot ablation process and the corneal remodelling that occurs through healing ...

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 ...

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 ...

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 ...

High-performance nanophotonic devices require extreme depth-to-diameter ratios, which are notoriously difficult to fabricate.

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...
