Currently have 445cc moderate. If I go up to 485cc mod will I need to have the pocket increased or will it fit? (photos)

An increase in only 40 cc represents less than 10% increase.  As such, it is unlikely that significant pocket modifications will be needed, Nor will it look substantially different, only slightly.Best of luck!

 I agree that you should wait at least six months till things settle down and you can get an accurate idea of the size you truly are. But in most cases 40 mL is not much of a difference at all. In my experience patients usually have to go at least 80cc or 100cc before they really notice much of a difference !!

Hello,It is way too early to be assessing your results. You'll need a full 6 months from surgery to get a good idea about shape and size. At that point, determination of revision surgery can be made. Best of luck!

Two
months ago you underwent a lift with implants. 
The lift was required because the skin envelope was not strong enough to
hold your breasts in the proper position. 
Unfortunately, you added 445 cc implants, which weigh approximately 1
lbs each.  Your breasts are now under more
stress than before because of the additional weight.  Your breasts are going to drop and change
configuration.  At this time, you are
only two months out.  You need to wait
six months to see what will happen.  It
is possible the breasts can equal out without additional surgery.  But it is likely that you will need a
revision with smaller implants and a stronger lift.  There is really no significant difference
between 445 cc and 485 cc.    Best Wishes,Gary Horndeski, M.D.

A 30 cc change in implants is not going to be noticeable.  You will likely not need a pocket modification for that.

Yes, assuming the breast implants are kept in the same "pocket", revisionary surgery tends to be associated with less discomfort. Your plastic surgeon, knowing exactly what procedure is planned will be your best resource when it comes to more specific information and advice. Having said that, I think that significant adjustment of the breast implant pockets will not be necessary given the  breast implant size increase you mentioned.Make sure that you communicate your concerns/goals carefully. Best wishes for an outcome that you will be very pleased with.
