Hi I have pterygium and I also researched dr hirst, and it sounds as if he takes this seriously and I think its serious and I find american doctors treat pterygium in a slapstick way. dr. hirst states his procedure takes close to an hour and for a re-occurance maybe 2 hrs. so why are american dr's doing it in 10 minutes? this is what concerns me about living here in the US and not being able to find a good pterygium surgeon that can do a good job, any other suggestions? thanks for you information
