Also known as: IMT-NG
WA- NG Telescope Prothesis

The WA-NG telescope prosthesis (Figure 1) is the next generation telescopic implantable device which, when combined with the optics of the cornea, constitutes a telephoto system for improvement of visual acuity in patients with severe to profound vision impairment due to bilateral, end-stage age-related macular degeneration. The device is implanted in one of the patient's eyes. In this way, the implanted eye provides central vision and the non-implanted eye can continue to provide peripheral vision.

Eligibility Criteria

Age65 Years+
Sexall
Healthy VolunteersNo
Age GroupsOlder Adult (65+)

You may qualify if:

  • Bi-lateral, stable, moderate to profound (20/80 to 20/800) central vision impairment due to bilateral scotoma associated with end-stage macular degeneration, defined as retinal finds of bilateral, geographic atrophy or disciform scar with foveal involvment. Phakic in the operative eye. Must achieve a 5 letter improved with external telescope simulator.

You may not qualify if:

  • Evidence of active CNV or any ophthalmic pathology that compromises peripheral vision of fellow eye or predisposes eye rubbing. Previous intraocular of corneal surgery of any kind in operative eye. Retinal disease, optic nerve disease, diabetic retinopathy, retinal tears, or any introcular tumor or medical or ophthalmic condition that in the opinion of the investigator renders the subject unsuitable for participation.
