About this study
Official title: A Prospective Multicenter Clinical Study of the Implantable Miniature Telescope* in Patients With Central Vision Impairment Associated With AMD: IMT-UK Protocol (*IMT by Dr. Isaac Lipshitz)
Evaluation of pre and post-implantation management of patients with end-stage age-related macular degeneration (AMD) who have been implanted with the implantable telescope (IMT) under CE Mark indicated use. This study is designed to evaluate in particular the optimal parameters for patient selection for use of this device in routine clinical practice.

Questions about this trial
What is this clinical trial studying?
A study testing Telescope prosthesis in people with End Stage Macular Degeneration, run by VisionCare, Inc. at 4 sites in United Kingdom.
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 4 inclusion and 2 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: finished, as of the sponsor's last update on 14 Nov 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in United Kingdom. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Best-Corrected Visual Acuity (time frame: 1 year). 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 14 Nov 2012.
