The Doctor in London England who treats he erosion by laser is Mr Frank Lee.  He works privately at the Princess Grace and on the NHS at St.Georges Tooting.  His phone number is: 07775 563918  his email is: frank.lee@doctors.org.uk.  His PA is called Deborah Beddington.   I now have had the erosion lasered twice and it has eroded again.  So I have to go back into hospital for another procedure.  Its very distressing but unless I opt for surgery, which is too awful to contemplate, there is no alternative.   I have heard that there is a Doctor Shah in L.A who is removing the tape, and does good work.   Good luck with whatever you decide to do.  You have my utmost sympathy.   Kind regards  Christine
