Probably. If the incisions for your surgery were performed beneath the fold of the breasts or near your armpit, your chances of being able to breastfeed are good. If incisions were made around your areola, your milk production might be hindered, or your milk delivery system might be cut short — but it's not necessarily impossible.
Many mamas are able to breastfeed with implants. Go ahead and give breastfeeding your best shot, keeping a close watch on baby's weight gain and diaper output so that you can supplement if she isn't getting enough milk.
If you're concerned about the silicone in your breast implants, consider this: In scientific studies, no increased concentration of silicone was found in the milk of mamas with implants as compared to moms without implants. It's even been shown that silicone does not diffuse from the breast tissue into the ducts in cases where an implant has ruptured.
