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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether a new, objective way to fit toric contact lenses (for astigmatism) gives the same results as the traditional subjective method. About 45 adults with astigmatism will have their lens prescription checked both ways. The goal is to see if the new method can make lens fitting faster and more accurate.

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 participant and are willing and able to sign a Statement of Informed Consent. 3. They have spherical refractive error at the corneal plane between +4.00 to -7.00DS 4. They have refractive astigmatism at the corneal plane of 0.75 to 2.25DC in one eye. 5. They are able to achieve distance HCHL visual acuity of +0.10 logMAR or better in each eye 6. They are a current soft contact lens wearer or have previous experience of successful soft contact lens wear in the past 3 years. Exclusion Criteria: 1. Is participating in any concurrent clinical or research trial. 2. They have an ocular disorder which would normally contra-indicate contact lens wear. 3. They have a systemic disorder which would normally contra-indicate contact lens wear. 4. They are pseudophakic or aphakic. 5. They have had corneal refractive surgery. 6. They have any corneal distortion resulting from previous hard or rigid lens wear or have keratoconus. 7. Is using any systemic or topical medications that in the opinion of the investigator may affect contact lens wear or a study outcome variable.
