Wavefront-guided treatment relies on aberrometric refraction for programming the refractive correction of the eye, but manifest refraction LASIK continues to yield the most accurate refractive results ...

Orthokeratology proved reversible in a study, with refraction and visual acuity returning to baseline levels 1 week after the treatment was completed. The study was the first to show the effects of ...

Metasurfaces are a family of novel wavefront-shaping devices with planar profile and subwavelength thickness. Acoustic metasurfaces with ultralow profile yet extraordinary wave manipulating properties ...

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 ...

CAMBRIDGE, Mass., Oct. 9, 2019 /PRNewswire/ -- PlenOptika, maker of the QuickSee handheld autorefractor, today announced the publication of research showing their device produces measurements in ...

Nov. 19, 2003 (Anaheim) — Investigators comparing two kinds of intraocular lenses (IOLs) report that wavefront-corrected IOLs permit better reaction times than standard IOLs when elderly subjects are ...

Physicists are involved in an unusually heated debate over the reality of a new kind of refraction and about the possibility of making perfect lenses. Edwin Cartlidge reports. If you think science is ...
