Mutifocal techniques, in particular the multifocal ERG, are used in the diagnosis of ophthalmological diseases. The multifocal technique was developed in the early 1990s in the laboratory of Erich Sutter at the Smith-Kettlewell Eye Research Institute [ 1 ] [ 2 ] [ 3 ]
The multifocal ERG is used to record separate responses for different retinal locations. The international body concerned with the clinical use and standardization of the ERG, EOG, and VEP is the International Society for the Clinical Electrophysiology of Vision (ISCEV).

People who have a multifocal intraocular lens after their cataract is removed may be less likely to need additional glasses compared with people who have standard monofocal lenses.

They are also known as multifocal lenses, progressive addition lenses (PAL), varifocal lenses, progressive power lenses, graduated prescription lenses, or progressive spectacle lenses. History [ edit ]
The retina (from Latin rete 'net'; pl. retinae or retinas) is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs.The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception.
