I have had a repeat corneal graft after trauma in 2012 made it fail.i am 9 months everything with the graft looks good...i know the chances of rejection are far more likley in a repeat graft but what are the percentages? I cant find anywhere online and my surgeon hasnt really told me he just said its a higher chance,also can corneal grafts last a life time?thanks p.s my original condition was keratoconus
