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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 observational study looks at people who have already had cataract surgery with a Clareon Vivity lens implant. Researchers want to see if the lens's position—how centered and tilted it is—affects how well patients see. Participants will have their eyes examined and their medical records reviewed to check for any link between lens movement and vision quality.

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 a link is found between lens position and vision quality, it could help surgeons optimize lens placement for better outcomes.
What could go wrong
This is an observational study, so it cannot prove cause and effect. 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: * Age ≥ 18 years * History of adult cataract and uneventful, refractive cataract surgery with Clareon® Vivity® or Vivity® Toric intraocular lens (IOL) implantation with manifest refraction spherical equivalent (MRSE) within ±1.00 D * Willing to undergo an eye exam with pupil dilation Exclusion Criteria: * Moderate to severe posterior capsule opacification (2+ or more) * Yttrium aluminum garnet (YAG) laser capsulotomy within 1 month prior to enrollment * Laser-assisted in situ keratomileusis (LASIK) or photorefractive keratectomy (PRK) within the one year prior to IOL implantation or any time after IOL implantation * Any previous ocular surgery (excluding YAG, LASIK, PRK) * Clinically significant ocular pathology; severe diabetic retinopathy, age-related macular degeneration (AMD), glaucoma, severe dry eye, irregular astigmatism, zonular weakness, pseudoexfoliation, ocular trauma * Any additional procedure(s) at the same time as the Vivity implantation including but not limited to microinvasive glaucoma surgery (MIGS) * Women who are pregnant at the time of screening (based on self-reported history) * Medical or other problems which in the opinion of the investigator will render study participation unsafe
