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 Results may not be published yet.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

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.

Summary

This study looks at whether Systane COMPLETE artificial tears can improve dry eye symptoms and help doctors better predict cataract surgery outcomes. About 140 cataract patients with dry eye will use the drops before and after surgery. Researchers will measure changes in eye shape and dryness to see if the drops make a difference.

What this could mean

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

Active substance
Systane COMPLETE (artificial tears with mineral oil and phospholipids)
What this could lead to
If it works, this could show that using these eye drops before and after cataract surgery improves dry eye symptoms and helps doctors better predict surgical results.
What could go wrong
This is a small, early-phase extension study with only 140 participants. The eye drops are already approved for dry eye, so the main question is about added benefit for surgery planning, not a breakthrough.

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

Inclusion Criteria (Experimental group ): Cataract patients who participated in the "Optimizing the Ocular Surface with Systane COMPLETE in Patients with Dry Eye Planning for Cataract Surgery" trial (Research Ethics Committee Approval Number: 202311109MIPD) and did not withdraw from the trial midway. Exclusion Criteria (Experimental group ): Patients unwilling to participate in this trial after surgery. Inclusion Criteria(Control group): * Cataract patients aged between 20 and 85 years. * Patients with normal cognitive function who are able to complete the dry eye questionnaire (with - responses recorded by the research team) and are willing to undergo phacoemulsification and intraocular lens implantation under topical anesthesia. Exclusion Criteria (Control group): * Unable to answer the questions in the dry eye survey. * Ocular trauma or ocular surgery in the planned surgical eye, active ocular infection, and obvious abnormalities in ocular surface or eyelid margins other than MGD cause decreased visual acuity other than cataracts. * Dry eye signs: Corneal Fluorescein Staining CFS (+) to exclude any corneal abnormalities or epithelial defect. * Systemic drug use, including tetracycline derivatives, antihistamines, and isotretinoin. * Using dry eye medication at screening stage.
