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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a new digital guidance system that helps surgeons place toric lenses more accurately during cataract surgery. Researchers will compare the system's alignment calculations to standard methods and check vision and astigmatism one month after surgery. The study involves 100 eyes from patients having routine cataract surgery with toric lenses.

What this could mean

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

Active substance
Cassini Guidance with HUD (digital guidance system)
What this could lead to
If successful, this system could help surgeons place toric lenses more accurately, potentially reducing blurry vision after cataract surgery.
What could go wrong
This is a small, early observational study with only one surgeon, so results may not apply to all patients or settings. The system may not improve outcomes enough to justify its use.

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

Study facts

What this study's own registry entry says, in plain language.

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 100 people

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

Started

Nov 2025

Expected to finish

Oct 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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

Inclusion criteria: * Patients undergoing uncomplicated cataract surgery with toric IOL implantation, * Eyes implanted with a toric IOL. Exclusion criteria: * Ocular comorbidity likely to impair postoperative visual acuities, or * History of ocular trauma or zonular instability, or * Previous refractive surgery, or * Irregular corneal astigmatism or keratoconus, or * Patients with physical or intellectual disabilities that may prevent reliable fixation or comprehension (e.g. Down's Syndrome, Parkinson's Disease), or * Patients with unreliable biometry measurements, or * Severe dry eye disease or ocular surface disease.
