What's wrong with my implants? I'm 3 years post op, 400cc mentor siltex round moderate + cohesive gel under the muscle (Photo)

Do I need to have these taking out then let them heal and then have a revision for a natural good result where my nipple is central to the implant or is it possible to have it done in one go, I think I would have them slightly smaller if possible, I was a 32b/c before and I don't think I needed a lift and there was no recommendation off the doctor to have one but because the implants are in my opinion to high it now makes me look like I need one which I really don't want if I can help it!
