About this study

Official title: A Prospective, Multicenter Clinical Study of the Implantable Miniature Telescope, Model SING in Patients with Central Vision Impairment Associated with End-stage Age-related Macular Degeneration (AMD)

The objective of this study is to determine the safety and effectiveness of the smaller incision, new generation (SING), implantable miniature telescope (IMT) in patients with moderate-severe central vision loss due to late-stage age-related macular degeneration (AMD).

Read the detailed description

Following completion of informed consent, patients will be evaluated for eligibility to enroll into the study, including assessment of their best-corrected distance- and near- visual acuity with and without refraction, and also when using an external telescope simulator (ETS) to determine if they are likely to benefit from receiving the IMT. If eligible, they will be scheduled for out-patient surgery to implant the IMT during routine cataract surgery. Following implantation, patients will return for 5 post-operative follow-up visits over a period of approximately 12 months. Additionally, patients will have up to 12 rehabilitation/training visits with a low vision specialist

Questions about this trial

What is this clinical trial studying?

A study testing smaller incision, new generation implantable miniature telescope (SING-IMT) in people with Age-Related Macular Degeneration and Geographic Atrophy, run by VisionCare, Inc. at 10 sites in United States.

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 13 inclusion and 32 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: looking for participants now, as of the sponsor's last update on 3 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Rebecca Kammer, OD, PhD (+1 (714) 728-1575, rkammer@samsaravision.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Effectiveness Outcome (time frame: Approximately 12-months post-operatively (330-420 days)). The study lists 2 primary outcomes in all. 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 3 Dec 2024.
