What is being measured
The primary outcome is the main question the study is designed to answer.
Central corneal thickness (CCT)
Central corneal thickness will be measured in microns. This outcome measure will be analyzed using Bland-Altman Limits of Agreement, repeatability, reproducibility, and percent coefficient of variation (repeatability and reproducibility) methods.
Measured: Day 1
Lens thickness (LT)
Lens thickness will be measured in microns and analyzed using Bland-Altman Limits of Agreement, repeatability, reproducibility, and percent coefficient of variation (repeatability and reproducibility) methods.
Measured: Day 1
Anterior chamber depth (regression) (ACD-R)
Anterior chamber depth (the physical length from the anterior cornea to the anterior lens) will be measured in microns and analyzed using Bland-Altman Limits of Agreement, repeatability, reproducibility, and percent coefficient of variation (repeatability and reproducibility) methods.
Measured: Day 1
Axial length (regression) (AL-R)
Axial length (the distance between the back and front of the eye) will be measured in millimeters and analyzed using Bland-Altman Limits of Agreement, repeatability, reproducibility, and percent coefficient of variation (repeatability and reproducibility) methods.
Measured: Day 1
Secondary outcomes (2)
Anterior Chamber Depth Sum of Segments (ACD-SoS)
ACD-SoS is calculated by calculating the individual corneal thickness and aqueous depth segments, applying the known refractive indices for each segment, and summing the resultant measurement of each segment. ACD-SoS will be measured in microns and analyzed using Bland-Altman Limits of Agreement, repeatability, and reproducibility methods.
Measured: Day 1
Axial Length Sum of Segments (AL-SoS)
AL-SoS is calculated by calculating the individual corneal thickness, aqueous depth, lens thickness and vitreous length segments, applying the known refractive indices for each segment, and summing the resultant measurement of each segment. AL-SoS will be measured in millimeters and analyzed using using Bland-Altman Limits of Agreement, repeatability, and reproducibility methods.
Measured: Day 1

Questions about this trial
What is this clinical trial studying?
An observational study of Normal Eyes and Abnormal Eyes, run by Cylite Pty Ltd 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 3 inclusion and 4 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 5 Aug 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?
Central corneal thickness (CCT) (time frame: Day 1). The study lists 4 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 5 Aug 2025; AzTrials last refreshed its copy on 6 Nov 2026.
