Preoperative and Postoperative Refractive and Topographic Evaluation in Patients With Primary Pterygium: Comparison of Two Surgical Techniques

NCT07742995 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 78

Last updated 2026-08-03

No results posted yet for this study

Summary

This study evaluated changes in refractive status and corneal topography before and after surgical treatment of primary pterygium. Patients undergoing pterygium excision were treated with either conjunctival autograft or amniotic membrane transplantation. Visual acuity, refractive error, and corneal topographic parameters were assessed before surgery and after postoperative follow-up to compare the effectiveness of both surgical techniques in restoring corneal optics and improving visual outcomes.

Conditions

  • Primary Pterygium
  • Astigmatism

Interventions

PROCEDURE

Conjunctival Autograft

Surgical excision of primary pterygium followed by transplantation of an autologous superior temporal conjunctival graft to cover the bare scleral bed.

PROCEDURE

Amniotic Membrane Transplantation

Surgical excision of primary pterygium followed by placement of preserved amniotic membrane over the bare scleral bed.
