Conjunctival Transpositional Pterygium Surgery: A Prospective Single-Arm Interventional Study

Overview

This prospective single-arm interventional study evaluates the recurrence rate and functional outcomes following conjunctival transpositional pterygium surgery without bare sclera formation. The technique involves mobilization and transposition of the pterygium tissue while preserving Tenon's layer and avoiding adjunctive therapies.

Interventions

  • Procedure Conjunctival Transpositional Pterygium Surgery
    A conjunctival incision was created at the upper and lower limbus to allow adequate tissue mobilization. The pterygium tissue is dissected off the corneal surface without complete excision or creation of a bare sclera defect. The fibrovascular tissue is mobilized and transposed inferiorly within the subconjunctival plane and secured with absorbable sutures. Tenon's tissue is preserved, and no adjunctive therapy is used.

Primary outcome measures

  • Pterygium Recurrence [Time frame: 12 months]
Secondary outcome measures (2)
  • Visual Acuity [Time frame: 12 months]
  • Refractive Astigmatism [Time frame: 12 months]
