About this study
Official title: Pilot Study of WA-NG Telescope Prosthesis in Patients With Central Vision Impairment Associated With End-stage Age-related Macular Degeneration
This is a pilot study to evaluate the safety of the Model WA-NG telescope prosthesis in patients with bilateral moderate to profound central vision impairment due to end-stage age-related macular degeneration.
Read the detailed description
Patients will be screened for eligibility and informed consent will be obtained from those who meet screening criteria and are interested in participating in the study. Eligible patients will be examined preoperatively to obtain a medical history and to establish a baseline for ocular condition. Baseline measurements will include successful use of an external telescope.
Postoperatively, patients will undergo ophthalmic evaluation at regular intervals as specified in this protocol and will be required to return for 6 to 10 additional visits for vision training with a low vision specialist.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Telescope prosthesisDevice
Also called IMT-NG
Monocular implantation of the telescope prosthesis after cataract extraction
WA-NG Telescope ProthesisDevice
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.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Telescope prosthesis and WA-NG Telescope Prothesis in people with Age Related Macular Degeneration, run by VisionCare, Inc. at 1 site in Israel.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 10 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Positional Stability (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jul 2020.
