What is "bioptics"

Bioptics may refer to:

• Bioptics (device), head-mounted eyeglasses of extreme magnification, which look somewhat similar to binoculars or which are mounted on existing glasses, to improve the distance vision of those with extreme vision impairment, most commonly those with albinism. Also known as a bioptic telescope.
• Bioptics (surgery), a combinatorial vision-correction surgical technique, pioneered by Roberto Zaldívar, in which refractive error is treated on both the lenticular and corneal optical planes.

Bioptics is a combinatorial vision-correction refractive surgical technique performed by ophthalmologists, in which refractive error of the eye is treated on both the lenticular and corneal optical planes. The dual technique was pioneered, and the term coined, by Roberto Zaldívar. The procedure is increasing in popularity (as of 2006).

Bioptics, also known as a bioptic in the singular, and sometimes more formally termed a bioptic telescope, is a term for a pair of vision-enhancement lenses. They magnify between two and four times, and are used to improve distance vision for those with severely impaired eyesight, especially those with albinism. They can either be a combination of head-mounted eyeglasses (termed the "carrier") and binoculars, or be designed to attach to existing glasses. Some use monoculars which have small telescopes mounted on, in, or behind their regular lenses, so that they can look through either the regular lens or the telescope. Newer designs use smaller lightweight mini telescopes magnifying up to six times, which can be embedded into the spectacle glass and improve aesthetic appearance. The mini telescopic eyeglasses have been shown to be used in the treatment of nystagmus. In some jurisdictions, those with low vision may be permitted to drive automobiles when using Bioptics.
