Summary

This study tests a new trifocal intraocular lens (IOL) for people having cataract surgery. The lens is designed to help see clearly at near, intermediate, and far distances. Researchers will compare the new lens to a commercially available one in 66 participants, measuring distance vision under bright light. The trial is not yet recruiting.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance: trifocal intraocular lens (IOL) implanted during cataract surgery
What this could lead to: If successful, this lens could provide clearer vision at multiple distances after cataract surgery, potentially reducing the need for glasses.
What could go wrong: This is an early-stage device comparison with only 66 participants. Results may not apply to all patients, and risks include typical surgical complications like infection or lens dislocation.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Key Inclusion Criteria: * The calculated power needed for the artificial lens (IOL) must be between +15.0 and +25.0 D in each eye, designed to bring subject vision as close to "0.0" (neutral) as possible, meaning they will not be strongly nearsighted or farsighted after surgery. * Subjects must have low levels of astigmatism (misshapen cornea) in the eyes (less than 1.00 D). * In the doctor's opinion, the subjects have the potential to achieve good vision (0.2 logMAR, which is roughly 20/32 Snellen or better) in each eye after the surgery, when wearing the best possible spectacles or contact lenses. * Other protocol-specified inclusion criteria may apply. Key Exclusion Criteria: * Clinically significant corneal diseases which may, according to the investigator's medical opinion, adversely affect visual outcomes. * Any ocular or systemic health condition or medical issue that, in the investigator's medical opinion, could make the study results unreliable, prevent the person from finishing the study, or increase their safety risk. * People who want to have one eye set for distance vision and the other for near vision. * The doctor expects significant blurry vision (astigmatism) after the procedure. * Other protocol-specified exclusion criteria may apply.
