Dear Mrs Kat,
Just a letter to say thank you for doing the surgery and that the procedure has now settled down.
Overall the procedure has been a real success and has ticked all the boxes. My main concern was to be able to see out better and this was an immediate effect. It has also had the secondary effect of making me look better. I am happy and smile when I look in the mirror and therefore have improved my self esteem.
It must also be said that the whole package -letters, hospital, and your reception staff were all excellent.
