Hello again and thanks for waiting.
I have worked out an answer for you below ...
1. I am not sure about using a staple but there are a couple of procedures described to suture the cherry eye protrusion back into it's normal position with very fine suture material, these are generally called tie back procedures. While it is possible to just cut the cherry eye out this is not recommended as a small number of cases go on to develop a condition called dry eye. Also some vets just leave a cherry eye as it is, while it is a bit unsightly in most cases it will not cause any harm to the dog's eye.
I personally go for the tie back procedure if I can ...
2. In the hands of an experienced vet the tie back procedure is a very quick and simple operation which will take ten minutes or so, however vets can charge whatever they want so prices could vary from around a couple of hundred dollars to very much more. The best plan is to talk this point over with the vet concerned first.
3. Here is a link to an accurate article which covers the topic : LINK
