Pentagonal vs quadrangular conjunctival autograft in pterygium surgery: a comparative study on graft retraction

Designing the conjunctival autograft in a pentagonal shape-mimicking geodesic dome architecture and conforming to the eye's spherical structure-enhances compatibility with the recipient conjunctiva and improves resistance to physical traction forces. This design effectively reduces the incidence of graft retraction and other related complications, providing a more favorable surgical option for pterygium treatment.
