Study summary

Superior bulbar conjunctival autograft is the standard procedure to reduce recurrence after pterygium excision. However, harvesting superior conjunctiva causes tissue scarring, which may compromise the site for potential future glaucoma filtering surgeries. This study evaluates whether harvesting a sutureless autograft from the inferior bulbar/forniceal conjunctiva provides comparable graft stability, pain levels, and recurrence rates while preserving the superior conjunctiva.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients aged 30 years or older of any gender.
  • Unilateral or bilateral primary active nasal or temporal pterygium requiring surgical excision.
  • Patient willing and capable of adhering to the scheduled post-operative follow-up visits (1 day, 1 week, 1 month, 3 months, and 6 months).
  • Provided signed, written prior to enrollment.

Exclusion criteria

Exclusion Criteria:

  • Recurrent pterygium or pseudopterygium.
  • Presence of cicatrizing ocular surface diseases (e.g., ocular cicatricial pemphigoid, Stevens-Johnson syndrome, chemical burns, or ocular trauma).
  • Pre-existing glaucoma, ocular hypertension, or history of previous conjunctival surgery in the study eye.
  • Active ocular infection, severe blepharitis, or dry eye syndrome.
  • Known allergy or to local anesthetics, fluoroquinolones, or topical .
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Study arms

  • Active comparator
    superior conjunctival autograft

    Pterygium excision followed by preparation and placement of a sutureless autograft harvested from the superior limbal/bulbar conjunctiva.

    Other: Sutureless Superior Conjunctival Autograft (CAG)

  • Experimental
    inferior conjunctival autograft

    Pterygium excision followed by preparation and placement of a sutureless autograft harvested from the infronasal/inferior bulbar conjunctiva.

    Other: Sutureless Inferior Conjunctival Autograft (CAG)

Interventions

  • OtherSutureless Superior Conjunctival Autograft (CAG)

    Following local anesthesia with topical proparacaine 0.5% and subconjunctival 2% lidocaine infiltration, standard surgical excision of the primary pterygium head and body is performed along with meticulous clearance of corneal and scleral bed fibrovascular tissue. A thin, donor conjunctival autograft matching the dimensions of the bare scleral bed (measured via surgical calipers) is harvested from the superior limbal/bulbar conjunctiva, incorporating limbal stem cell tissue. The graft is transferred to the recipient site maintaining correct orientation (limbus-to-limbus). Fixation is achieved suturelessly without the use of synthetic sutures. Pressure is applied over the graft for 5 to 10 minutes to ensure firm apposition prior to monocular eye patching.

  • OtherSutureless Inferior Conjunctival Autograft (CAG)

    Following local anesthesia with topical proparacaine 0.5% and subconjunctival 2% lidocaine infiltration, standard surgical excision of the primary pterygium head and body is performed along with meticulous clearance of corneal and scleral bed fibrovascular tissue. A thin, donor conjunctival autograft matching the dimensions of the bare scleral bed (measured via surgical calipers) is harvested from the infronasal / inferior bulbar and forniceal conjunctiva, deliberately sparing the entire superior bulbar conjunctiva for potential future ocular surgeries. The graft is transferred to the recipient site maintaining correct limbus-to-limbus orientation. Fixation is achieved suturelessly without the use of synthetic sutures. Pressure is applied over the graft for 5 to 10 minutes to ensure firm apposition prior to monocular eye patching.

What researchers measure

Primary outcomes

  1. Pterygium Recurrence Rate

    Presence of fibrovascular tissue regrowth crossing the corneo-limbal junction onto the clear cornea .

    Time frame: Evaluated at 6 months postoperatively

  2. Graft Stability and Adherence

    Evaluated on slit-lamp examination as stable, partially displaced, fully displaced, retracted, or lost.

    Time frame: Evaluated on Day 1, Week 1, Month 1, Month 3, and Month 6

Secondary outcomes

  1. Postoperative Pain Levels

    Patient self-reported pain score assessed on a standardized 10-point Visual Analog Scale (VAS) (0 = No Pain, 10 = Worst Possible Pain).

    Time frame: Day 1, Week 1, and Month 1 postoperatively

  2. operative time

    time spent at surgery from local anaesthesia injection to graft placement

    Time frame: at surgery

  3. donor site healing

    evaluated on slit lamp as time needed for the donor site to achieve complete healing

    Time frame: Day 1, Week 1, and Month 1 postoperatively

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2025 to primary completion in Jan 2026, 8 months.

Of 18 interventional studies with no phase under Pterygium, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 28. This study's 8 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
