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 This study
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

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.

Summary

This study looks at how removing a pterygium (a fleshy growth on the eye) and replacing it with a small piece of the patient's own eye tissue changes the shape of the cornea. Researchers will measure the cornea's curve before and one month after surgery in 130 adults aged 30 to 70. The goal is to see if this surgery reduces astigmatism and improves vision quality.

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 130 people

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

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.

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

Inclusion Criteria: * Adults of either sex aged \>30 to 70 years. * Phakic eyes. * Primary pterygium, Grade II or Grade III (as per protocol grading). * Presence of corneal astigmatism on pre-operative assessment. * Scheduled for pterygium excision with conjunctival autograft transplantation at the study site. * Able to provide written informed consent and to attend the 1-month postoperative assessment. Exclusion Criteria: * Pseudophakic or aphakic eyes. * Recurrent pterygium. * Prior keratoplasty or trabeculectomy in the study eye. * Keratoconus or other corneal pathologies that can independently induce astigmatism. * Lenticular astigmatism or significant lens pathology affecting refraction. * Eyes planned for simple pterygium excision without conjunctival autograft. * Any ocular condition or systemic illness judged likely to interfere with keratometric or refractive measurements, follow-up, or surgical safety.
