What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tracks 400 adults with cataracts to see how three different toric intraocular lenses rotate after surgery. Rotation is measured at several follow-up visits over three months. The goal is to find which lens stays most stable and help doctors choose the best option for each patient.

What this could mean

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

Active substance
toric intraocular lenses (TECNIS Toric II, AcrySof IQ Toric, AT TORBI 709M)
What this could lead to
If successful, this could help surgeons choose the best lens for each patient to reduce rotation and improve vision after cataract surgery.
What could go wrong
This is an observational study, not a treatment trial. It may not lead to immediate changes in practice, and results may not apply to all patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

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

About 400 people

The number the study aims to enrol. It can still change while the study runs.

Show the full entry requirements

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

Inclusion Criteria: * Adults aged 18 years or older with age-related cataract scheduled for phacoemulsification cataract surgery. * Presence of regular corneal astigmatism requiring toric intraocular lens implantation. * Eligible for implantation of one of the three study toric intraocular lenses based on preoperative evaluation. * Ability to understand the study procedures and provide written informed consent. Exclusion Criteria: * History of prior ocular surgery in the study eye. * History of ocular trauma in the study eye. * Irregular corneal astigmatism or corneal pathology affecting reliable biometric measurement. * Intraoperative complications, including anterior capsular tear or posterior capsular rupture. * Inadequate pupillary dilation during surgery or postoperative examinations. * Evidence of zonular weakness, zonular dialysis, or lens subluxation. * Active ocular infection or inflammation. * Any other ocular or systemic condition judged by the investigator to potentially affect intraocular lens stability or study outcomes.
