I have CI's in both ears, have had one for 9 years and the other for 1 year.
I don't care what anyone says....the CI is a very powerful hearing aid, period. Just like all other hearing aids, no two people get the same results.
While I applaud Cochlear (and others) for creating this ingenious device, the medical community needs to stop pushing it as a "cure", because it is not a cure. It helps most of us hear, but not all of us.
It is probably the most controversial issue here. We can argue nonstop about the pros/cons. You will never hear me say "The CI is great, everyone should try it out".
If you are happy being deaf, with or without hearing aids, then a CI is not necessary. If you have lost your hearing and/or want to hear more, the CI is worth looking into. It is all up to the individual and his/her surgeon.
If I lived and worked with people that have no issues with me being deaf, and being deaf did not affect my chances of finding a good paying job, I probably would not have gotten the CI. Still, I am glad to have my CI's, as they make a difference.
