Comparing Two Surgical Methods to Prevent Pterygium Regrowth
A study testing Conjunctival Rotational Flap and Conjunctival Autograft in people with Pterygium, run by College of Physicians and Surgeons Pakistan.
Trial summary
This study compares two surgical techniques for preventing the regrowth of a pterygium, a non-cancerous growth on the eye. After surgically removing the pterygium, surgeons will cover the area with either a flap of nearby tissue that is rotated into place (Rotational Flap) or with a free graft of tissue taken from… Read more about this study

About this study
Official title: Evaluation of Conjunctival Rotational Flap Compared to Conjunctival Autograft After Surgical Removal of Primary Pterygium: A Randomized Controlled Trial
This study compares two surgical techniques for preventing the regrowth of a pterygium, a non-cancerous growth on the eye. After surgically removing the pterygium, surgeons will cover the area with either a flap of nearby tissue that is rotated into place (Rotational Flap) or with a free graft of tissue taken from under the upper eyelid (Autograft). The main goal is to see which method is better at preventing the pterygium from growing back over a 6-month period. A total of 342 patients with a primary pterygium will be randomly assigned to one of the two surgical groups.
Read the detailed description
This is a single-center, prospective, randomized controlled trial to be conducted at the Department of Ophthalmology, Saidu Group of Teaching Hospital, Swat. The study aims to compare the efficacy of the Conjunctival Rotational Flap versus the Conjunctival Autograft in reducing recurrence rates following primary pterygium excision. Adult patients aged 18-60 with primary pterygium will be enrolled. Participants will be randomly allocated into two groups: Group A (Conjunctival Rotational Flap) and Group B (Conjunctival Autograft). The primary outcome measure is the absence of clinical recurrence, defined as fibrovascular tissue crossing ≥ 1 mm onto the cornea, assessed at the 6-month postoperative follow-up visit via slit-lamp examination. Secondary outcomes may include operative time and postoperative complications. Data will be analyzed using SPSS version 23, with a p-value of ≤ 0.05 considered statistically significant.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Conjunctival Rotational FlapProcedure or surgery
A surgical technique where adjacent conjunctival tissue, remaining partially attached, is rotated to cover the exposed sclera after pterygium excision.
Conjunctival AutograftProcedure or surgery
A surgical technique where a free graft of conjunctiva is harvested from the superior bulbar conjunctiva and sutured or glued over the scleral defect after pterygium excision
| Study group | Role | What they receive |
|---|---|---|
| Rotational Flap | Experimental | A hinged conjunctival flap created adjacent to the excision site and rotated to cover the scleral defect while maintaining partial vascular attachment. Receives: Procedure: Conjunctival Rotational Flap; Procedure: Conjunctival Autograft |
| Conjunctival Autograft | Active comparator | A free conjunctival graft harvested from the superior bulbar conjunctiva and transplanted to the scleral bed after pterygium excision. Receives: Procedure: Conjunctival Rotational Flap; Procedure: Conjunctival Autograft |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pterygium Recurrence Rate
Absence of clinical recurrence, defined as a quiet ocular surface with no fibrovascular regrowth ≥ 1 mm onto the cornea, as measured by slit-lamp examination.
Measured: 6 months postoperatively
