简要总结
The purpose of this study is to determine if there is any difference in the surgical time when the surgery is performed with a graft taken from under the upper lid versus lower lid. The investigators will also be recording the level of pain felt by patients after surgery, any difficulties during or after surgery, and if the pterygium grows back.
