Capella Scientia: developing Unity DX to measure eyes with cataract.

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, noninterventional, single-arm, unmasked, multicenter effort enrolling four cohorts simultaneously to collect biometry and aberrometry data with the next-generation Unity DX device. Measurements will be taken at sites in India, Spain, and the Philippines and compared with data from other biometers (SCDX, IOLMaster 700, and Argos with Alcon Image Guidance). Eligible adults with cataracts who can tolerate pupil dilation and fixation will undergo imaging visits without any interventional treatment. The collected data are intended to characterize device performance and support development and validation.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Able to understand and sign an IRB/IEC approved consent form;
* Willing and able to attend study visit(s) as required by the protocol;
* Consenting age at the jurisdiction of study site;
* Other group-specific, protocol required inclusion criteria may apply.

Exclusion Criteria:

* Women of child-bearing potential;
* Unable to fixate due to nystagmus or other eye movement abnormality (e.g., significant strabismus);
* Unclear optical media preventing data capture from all devices in the study;
* Contraindicated for pupil dilation (e.g., narrow angles, allergies) per investigator's clinical judgment;
* Any ocular disease and/or condition that, in the investigator's clinical judgment, may put the subject at significant risk, may compromise study results, or may interfere significantly with the subject's participation in the study;
* Other group-specific, protocol required exclusion criteria may apply.
