Compressed continuous suture versus conventional suture for conjunctival graft fixation in pterygium surgery
Comparison of Compression Continuous Suture Versus Conventional Suture for Autologous Conjunctival Implant Fixation in Primary Pterygium Surgery: a Randomized Controlled Trial
This trial will see if a compressed continuous suture or a conventional suture is better at securing an autologous conjunctival graft and reducing symptoms after primary pterygium surgery.

What this trial studies
This single-center interventional trial at Tianjin Eye Hospital compares two techniques for fixing autologous conjunctival grafts after excision of primary pterygium: a compressed continuous suture and a conventional suture method. Adults with primary pterygium that invades the cornea by 2–5 mm and without prior eye surgery or active ocular inflammation are eligible. Outcomes include graft stability, postoperative discomfort and inflammation, complications (such as granuloma or hemorrhage), ease and timing of suture removal, and pterygium recurrence. Participants receive one of the two suture techniques during surgery and are followed at scheduled postoperative visits to compare healing, symptoms, and recurrence rates.
Who should consider this trial
Good fit: Ideal candidates are patients with primary pterygium invading 2–5 mm of the cornea who have not had prior eye surgery, have no active ocular inflammation, and can attend regular follow-up visits.
Not a fit: Patients with recurrent or pseudopterygium, a history of prior eye surgery, active ocular inflammation, or inability to comply with follow-up are unlikely to benefit from this comparison.
Why it matters
Potential benefit: If successful, the compressed continuous suture could reduce postoperative irritation and inflammation, simplify the procedure and suture removal, and lower the chance of pterygium coming back.
How similar studies have performed: Previous research indicates that suture technique and alternatives like fibrin glue can influence comfort and recurrence after pterygium surgery, but direct comparisons of compressed continuous suture versus conventional suture are limited.
