What participants receive

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

  • BI Anterior Segment ModeDevice

    Single eye measurement in Anterior Segment Mode

  • BI Anterior Segment and IOL Biometry ModeDevice

    Eye measurement 3 times with and without dilation in IOL biometry and Anterior Segment mode

All except Anterior Segment Pathology3 repeat measurements with and without dilation for all eyes except Anterior Segment Pathology
Receives: Device: BI Anterior Segment and IOL Biometry Mode

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of successfully scanned biometry images of the eye

    Percentage of successfully scanned biometry images of the eyes per scan mode. Success is defined as agreement of the subjective assessment of the operator and the auto assessment of the device.

    Measured: 1 day

  2. Repeatabiltiy of specific parameters of the biometry images of the eye

    Repeatability of specific parameters stratified by different eye pathologies

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

An observational study of Normal Eyes and Eye Abnormalities, run by Heidelberg Engineering GmbH 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 8 inclusion and 7 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 12 Jun 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?

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?

Percentage of successfully scanned biometry images of the eye (time frame: 1 day). 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 12 Jun 2025.
