About this study

Official title: Early Feasibility Study to Evaluate the Safety and Effectiveness of the Intraoperative Pseudophakic Capsular Lens Magnifier for Age-Related Macular Degeneration (IOPCL AMD-MAG) for Secondary Implantation in the Capsular Bag to Improve Near Vision in Subjects With Age-Related Macular Degeneration After Cataract Surgery

This early feasibility study aims to improve near vision in subjects 55 years or older who have a clinical diagnosis of Age-Related Macular Degeneration. Subjects must have previously been implanted with either the Alcon Model SN60WF or Model SA60AT intraocular lens at least 6-months prior to receiving the IOPCL (intraocular pseudophakic capsular lens). Subject will be followed for a period of 12-months.

Read the detailed description

This will be a 12-month study, in which a maximum of 10 pseudophakic subjects from up to three clinical sites with a diagnosis of age-related macular degeneration will be enrolled. The IOPCL MAG (intraocular pseudophakic capsular lens magnifier) consists of a 4.5mm diameter optic. The IOPCL MAG is centered above the existing intraocular lens. The IOPCL MAG is designed to improve near vision of the AMD subject by providing magnification of 10 diopters in the central 1.8mm zone of the lens optic.

The primary objective of this study is to determine the stability of the IOPCL-AMD-MAG to successfully adhere to a pseudophakic intraocular lens (PCIOL) without slippage or rotation.

The secondary objective of this study is to determine if the IOPCL-AMD-MAG can improve uncorrected near vision in subjects previously implanted with the Alcon Models SN60WF or SA60AT.

Outcome simulation testing will be performed prior to the subject receiving the IOPCL. To qualify for the study the subject must demonstrate an improvement in uncorrected near visual acuity of 10 letters over baseline.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • IOPCL AMD MAGDevice

    The IOPCL MAG (intraocular pseudophakic capsular lens magnifier) consists of a 4.5 mm diameter optic. The central 1.8mm of the anterior surface has a power of 10.0 diopters. This IOPCL MAG will be implanted over an Alcon Model SN60WF or SA60AT intraocular lens to improve near vision.

Questions about this trial

What is this clinical trial studying?

A study testing IOPCL AMD MAG in people with Low Vision and Age Related Macular Degeneration, run by OnPoint Vision Inc at 1 site 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 21 inclusion and 28 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 31 Jan 2025. 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 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?

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?

Tilt of the PCIOL and IOPCL MAG Complex (time frame: 12 Months). The study lists 3 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 31 Jan 2025.
