What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looked at how accurately the Alcon Vision Suite with Argos biometer predicts the right lens power for people having cataract surgery. 106 adults aged 45 and older who chose either Clareon PanOptix or AcrySof Vivity lenses took part. The goal was to see if the device helps achieve the predicted vision target, reducing the need for glasses after surgery.

What this could mean

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

What this could lead to
If successful, this could help doctors choose the right lens power more accurately, leading to better vision after cataract surgery without glasses.
What could go wrong
This is a small, completed study focused on measurement accuracy, not a new treatment. Results may not apply to all patients or lens types.

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

Inclusion Criteria: Subjects are eligible for the study if they meet the following criteria: Note: Ocular criteria must be met in both eyes. * Age-related cataract surgery (or RLE) patients that select Clareon PanOptix or AcrySof Vivity IOL. * Gender: Males and Females. * Age: 45 or older. * Patients motivated to increase spectacle independence with relatively low incidence of visual phenomena. * Willing and able to provide written informed consent for participation in the study. * Willing and able to comply with scheduled visits and other study procedures. * Have good ocular health, with no pathology that compromises visual acuity (outside of residual refractive error). Exclusion Criteria: If any of the following exclusion criteria are applicable to the subject or either eye, the subject should not be enrolled in the study. * Ocular comorbidity (any previous ocular surgery, any signs of retinal disease, or glaucoma etc.) that might hamper post-operative visual acuity. * Irregular corneal astigmatism and keratoconus. * Post refractive eyes (i.e. LASIK or PRK or SMILE). * Patients with physical or intellectual disability (e.g. Down's Syndrome, Parkinson's Disease; unable to fixate). * Angle Kappa/chord mu ≥0.6. * Higher order corneal aberrations: \> 0.6 total RMS, \>0.3 coma, \>0.3 trefoil (to exclude irregular corneas). The principal investigator reserves the right to declare a patient ineligible or non-evaluable based on medical evidence that indicates they are unsuitable for the trial. Pregnancy has a known effect on the stability of refractions and visual acuity. As such, subjects who become pregnant during the study will not be discontinued but their data may be excluded from analyses of effectiveness.
