“Wavefront adds precision. With standard LASIK, a refractive outcome is usually equal to a patient’s spectacle correction, but not better. With wavefront-guided LASIK, the refractive outcome is equal ...

Researchers in Caltech's Andrew and Peggy Cherng Department of Medical Engineering have made a major step forward in medical imaging by taking inspiration from the field of astronomy. The paper ...

Engineers from Rice University and the University of Maryland have created full-motion video technology that could potentially be used to make cameras that peer through fog, smoke, driving rain, murky ...

Laser in situ keratomileusis (LASIK) was initially reported by Ioannis Pallikaris in 1990 and has since become an efficient and highly popular procedure in corneal refractive surgery. However, a ...

Diagnosing the degree of vision impairment is a difficult task for even experienced optometrists, since it depends on the subjective response of the person tested. Normally, it is based on reading out ...
