|---|---|---|
| Intelligent Retinal Implant System | Experimental | Not described Receives: Device: Intelligent Retinal Implant System |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Adverse Events as a Measure of Safety and Tolerability
All subjects undergo ophthalmological examinations in predefined intervals after implantation. Ophthalmological examinations include funduscopy, slit lamp examination and OCT. All adverse events are recorded and analysed.
Measured: Up to 18 month after implantation
Secondary outcomes (1)
Probable benefit
A series of vision test including grating visual acuity, light localization and contrast sensitivity is performed before and after implantation of the device.
Measured: Up to 18 months after implantation

Where is the study taking place?
The record lists 5 sites in France, Germany, Austria. 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?
Number of Adverse Events as a Measure of Safety and Tolerability (time frame: Up to 18 month after implantation). 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 17 Oct 2017.
