Another way of treating pterygium is by the bare sclera technique. In simple terms, it is a traditional procedure where the surgeon removes the pterygium tissue and does not replace it with a new tissue graft.
In comparison with pterygium surgery, the only point of difference is that the bare sclera technique leaves the white of the eye exposed to heal and recover on its own. However, on the other hand, this technique eliminates the risk of fibrin glue but increases the risk of pterygium regrowth.
