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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 investigates whether measurements from eye imaging devices can predict the tilt (misalignment) of an artificial lens implanted during cataract surgery. Researchers will use OCT and Scheimpflug cameras to measure the eye before and after surgery in about 110 adults. The goal is to develop a model that forecasts post-operative tilt, which could help surgeons choose the best lens and improve visual outcomes.

What this could mean

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

Active substance
Optical coherence tomography (OCT) and Scheimpflug imaging (IOLMaster 700, Casia 2, Pentacam HR)
What this could lead to
If successful, this could lead to better prediction and prevention of lens tilt after cataract surgery, potentially improving visual quality for patients.
What could go wrong
The study is observational and relatively small, so results may not apply to all patients. The predictive models may not be accurate enough for clinical use.

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

Inclusion Criteria: * Planned cataract surgery in one or both eyes * Above 21 years of age Exclusion Criteria: * Combined surgery (cataract plus glaucoma/vitreoretinal/corneal surgery) * Best corrected distance visual acuity below 0.05 Snellen * Pathologies that could have an influence on the post-operative tilt, such as pseudoexfoliation syndrome or previous ophthalmic trauma, or other reasons for phakodonesis. * Previous ophthalmic surgery that could have an influence on post-operative tilt, such as pars plana vitrectomy * In case of pregnancy (pregnancy test will be taken preoperatively in women of reproductive age)
