Performance Evaluation of Dream OCT: AP Study
What this study is about
This study will evaluate the clinical performance of a new swept-source OCT imaging device, the VG200D, and to evaluate substantial equivalence with a predicate device, the Cirrus 5000. Clinical performance will be assessed through an agreement and precision analysis of OCT measurement parameters.
View original scientific description
This study will evaluate the clinical performance of a new swept-source OCT imaging device, the VG200D, and to evaluate substantial equivalence with a predicate device, the Cirrus 5000. Clinical performance will be assessed through an agreement and precision analysis of OCT measurement parameters.
Interventions
DEVICE
This is an observational study only, all patients are imaged on the investigational device
This study is a non-significant risk study where enrolled patients are imaged on an investigational device and a predicate device
Primary outcome measures
Agreement results and Precision Results
Time frame: This study will last approximately 6 months
Primary endpoints include the agreement and precision results from the Anterior Segment OCT measurements for cornea and epithelial thickness in normal eyes and eyes with a corneal abnormality and the posterior segment OCT measurements for the retina, ganglion cell +IPL, RNFL, and optic nerve in normal eyes, eyes with glaucoma, and eyes with retinal pathology.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
