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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compared two types of soft multifocal contact lenses (Proclear 1 Day and Clariti 1 Day) to see which one people liked better. 67 adults who already wore contact lenses and needed reading glasses tried both lenses and rated their overall satisfaction. The goal was to help people with presbyopia (age-related blurry near vision) find a more comfortable and clear lens option.

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

Inclusion Criteria: 1. They are at least 18 years of age. 2. They understand their rights as a research subject and are willing and able to sign a Statement of Informed Consent. 3. They habitually use soft contact lenses (multifocal soft contact lenses, sphere lenses for monovision, sphere lenses for distance vision correction and spectacles for near vision correction,) and have done so for at least the past three months. 4. They have a minimum reading add of +0.75DS (based on their spectacle refraction) 5. They have spherical equivalent refractive error between +6.00 to -10.00DS at the corneal plane and refractive astigmatism of no greater than -0.75DC in each eye. 6. They are able to achieve distance HCVA of +0.10 logMAR or better in each eye. Exclusion Criteria: 1. They have an ocular disorder which would normally contra-indicate contact lens wear. 2. They have a systemic disorder which would normally contra-indicate contact lens wear. 3. They are aphakic. 4. They have had corneal refractive surgery. 5. They have any corneal distortion resulting from previous hard or rigid lens wear or have keratoconus.
