At the present time the traditional surgical handling of the pterygium with conjunctival implant presents high frequency. In this work the obtained results of a controlled clinic practice blind double are presented of the period of December from 2008 to December 2009, realized in the Medical Unit of Ambulatory Attention 231 of the Mexican Institute of the Public Health located in Metepec, Mexico State, in order to demonstrate the effectiveness and security of the alternative use of the radio sterilized amniotic membrane and intraoperative mitomycin C.
