Application of conjunctival autograft: The conjunctival autograft,
which remains attached to the superior
limbus, is now reflected onto the cornea
(epithelium to epithelium) and cut free
from the superior limbus with scissors
(Figure 2). The surgeon slides this graft
across the cornea, orienting its limbal
side to the limbus where the pterygium
was excised (Figure 3, on page 36). A
small droplet from the diluted thrombin syringe (black label) is applied to
the bare sclera (Figure 3), and a small
droplet from the fibrinogen (blue label)
syringe is applied to the underside of
the graft. The graft is then grasped with
two MacPherson forceps and flipped
onto the bare sclera. This allows the
two adhesive components to mix, and
the surgeon has about 30 seconds to
manipulate and orient the graft appropriately, such that the edges of the graft
are approximated with the cut-edges of
the surrounding conjunctiva and the
corneal margin is aligned with the limbus (Figure 3).
