Patent ID: 8070688

Claim:
A device for modulation of a pupil size, wherein: the device is configured for drug-free non-invasive modulation of a pupil size without actual contact with a patient's eye, the device consists of one or more units for placing externally to a patient's eye without actual contact with a patient's eye, and the device comprises an external source of an electric and/or magnetic field for placing externally to a patient's eye, said external source of the electric and/or magnetic field being configured and operable to produce the electric and/or magnetic field of desired intensity and direction having a required profile of the field in a region at a certain distance from the external source, such that temporal application of said field to an iris region in the patient's eye effects stimulation and/or neutralization of a nervous impulse to iris muscles associated with the pupil control, thus temporarily inducing mydriasis or miosis effect, the device thereby providing drug-free non-invasive modulation of a pupil size.
