Vaser is a type of liposuction, which uses ultrasonic vibration (kind of like a sonicare toothbrush) to first loosen the fat before it is sucked out. This is thought to minimize damage to blood vessels and nerves, while also providing a source of heat, which, in turn, improves postoperative skin tightening. It is still liposuction, however, and any duly trained and licensed physician (MD or DO) can perform it. Interestingly, liposuction was invented by a gynecologist and later perfected in the mid 80s by a dermatologist. Many board certified plastic surgeons and other surgeons have also contributed to the evolution of the procedures we perform today. I have seen bad results from surgeons (and nonsurgeons) of all kinds, including board certified plastic surgeons. Just because a doctor is a board certified plastic surgeon, does not guarantee that he or she can do the best job for you. A doctor with proper training and experience in liposuction, regardless of specialty, can get consistent excellent results. If your chosen physician has an applicable board certification, this can certainly increase the chances that he or she will get the kinds of results you are looking for. There is another board, the American Board of Cosmetic Surgery (ABCS), which also examines and certifies surgeons who meet their strict criteria (see the link below). These surgeons are all trained in some primary surgical specialty, such as Gynecology, in my case, and they then must meet the criteria to take and pass a written and oral board examination, before they can say they are "board certified." Many states, however, do not prevent a doctor who has no surgical training other than medical school and a weekend liposuction course to perform liposuction. Look at the doctor's training and credentials. Look at online reviews, before and after photos, and even interview a patient or two before you decide if you are making the right choice - most doctors have patients who do not mind talking about their experiences with prospective patients. If in doubt, ask the doctor where he or she trained in liposuction and how many cases they have done. Ask about what their primary specialty is and if it is not a surgical specialty, ask more questions, such as: what would happen in an emergency during surgery; do they have admitting privileges at a nearby hospital; is their surgical room accredited; how do they handle complications or unsatisfactory results. See the link below for more information on the ABCS and what it takes to become board certified.
