Implants alone are seldom the best choice in treating a significant tubular/tuberous deformity as in your case unfortunately demonstrates. I do not think that you will see much change/improvement from your present situation over time.
Since you had a very short nipple to infra mammary fold distance, the lower pole needed to be released completely to create a smooth transition from the breast fold to the prostheses. This can be performed secondarily but for that I would wait 6 months. This should be performed through a periareolar incision.
The link below is to a breast revision case I recently performed on a young lady who also developed a double-bubble deformity because her surgeon performed a straight-forward breast augmentation (re: did not release the lower pole during surgery) even though her breasts were slightly tuberous.
Hope that helps and good luck going forward,
