Researchers are evaluating a surgical technique called conjunctival transpositional pterygium surgery for patients with primary pterygium involving the cornea. This prospective single-arm interventional study aims to assess how often pterygium returns after surgery and how well patients recover their eye function without using adjunctive therapies. The study is sponsored by Zahedan University of Medical Sciences and focuses on preserving eye tissue during surgery to potentially improve outcomes. The surgery involves making incisions at the upper and lower limbus to mobilize the pterygium tissue without completely removing it or creating an exposed sclera area. The fibrovascular tissue is moved and secured with absorbable sutures while preserving Tenons tissue, and no additional treatments are applied. This technique is designed to reduce recurrence and maintain eye surface integrity. Participants will be followed for 12 months after surgery to monitor recurrence rates, visual acuity, and refractive astigmatism. Evaluations will include regular eye exams to measure these outcomes and ensure safety. The study involves adults aged 18 years and older with primary pterygium and requires informed consent. Total participation time spans at least one year for thorough follow-up.
