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.
Exclusion Criteria:
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.
Pterygium Recurrence
Recurrence is defined as fibrovascular regrowth toward the cornea or surgical failure.
Time frame: 12 months
Visual Acuity
Change in visual acuity measured in logMAR units.
Time frame: 12 months
Refractive Astigmatism
Change in refractive astigmatism measured as cylindrical power in diopters.
Time frame: 12 months
Plan to share: Undecided
