Liberty Vision has developed the iWand® to be a simple device for treating wet Age-Related Macular Degeneration

What is AMD?

Age-related macular degeneration or AMD is a disease associated with aging that gradually destroys sharp, central vision. Central vision is needed for seeing objects clearly and for common daily tasks such as reading and driving.

AMD affects the macula, the part of the eye that allows you to see fine detail. AMD causes no pain. In some cases, AMD advances so slowly that people notice little change in their vision. In others, the disease progresses faster and may lead to a sudden loss of vision in one or both eyes.

AMD is a leading cause of vision loss in Americans 60 years of age and older. Macular degeneration in the elderly is a major cause of blindness. Its prevalence increases to 30% in patients 75 to 85 years of age. We have created the Liberty Vision iWand(TM) to treat the wet, more severe form of AMD.

Our Method

Liberty Vision has developed a radiation therapy delivery system called the iWand® built to enable practitioners to deliver a prescribed dose of radiation to the eyes’ macular retina. The iWand® features a disc-shaped radioactive element at the end of our patented hand-held delivery system.

In addition, the iWand® is able to emit multiple points of light from the periphery of the tip which surround the radiation source. These lights are visible to the retinal specialist by looking through the pupil using an ophthalmoscope. As the lights encircle the treatment zone, they are used to positively locate the radiation treatment beneath the diseased macula. The iWand® light-guided radiation device was developed to be a simple and accurate system for delivering radiation to a target tissue.
