Helioscope optical biometer combining LED corneal topography and SS-OCT

Official title: Development of a Next-Generation Optical Biometer for Eyes With Cataract

Run by Cassini Technologies · NCT07325162 · Data updated 2026-11-12

This study will test whether the Helioscope can take accurate corneal shape and eye-length measurements in adults with cataracts to help choose the right intraocular lens power.

Is this trial a fit for you?

Likely a good fit

Adults aged 21 or older with cataract in at least one eye who can fixate and provide informed consent are appropriate candidates.

Probably not a fit

Patients who cannot reliably fixate, cannot provide informed consent, or whose media opacities prevent OCT imaging are unlikely to receive benefit from this device.

What this trial studies

The Helioscope combines a color LED–based corneal topographer with a novel swept‑source OCT (SS‑OCT) module to capture corneal shape and ocular biometry in a single device. The study collects Helioscope measurements in adults with cataract and compares them to readings from the Cassini Ambient topographer and the Argos SS‑OCT biometer. Data from cataractous eyes will be used to develop and refine the device’s software algorithms, with special attention to performance in dense cataract. Measurements are acquired at a single clinical site after informed consent and with eligibility limited to adults who can fixate.

Why it matters

Potential benefit: If successful, the Helioscope could provide faster, more complete biometry including corneal topography in cataract patients, improving intraocular lens power selection and refractive outcomes.

How similar studies have gone: Other swept‑source OCT biometers (for example Argos and IOLMaster 700) have shown reliable biometry performance, but combining LED color‑topography with SS‑OCT in one device is a newer approach still under development.
