Generally speaking, the better known SRS surgeons reliably perform a quality procedure. Prior to the surgery, you'll have the opportunity to meet with a surgeon, and you can discuss your expectations and priorities at that time, as well as having a chance to see if there's a rapport. The vast majority of clients are satisfied with the outcome, and most clients take their time, and choose the surgeon that's right. I chose my surgeon based upon location, cost, experience, and typical outcome. I had seen photos of his work and was impressed. I was impressed with his aftercare provisions. Internet searches led to many satisfied clients, so it was a complete package. There were several other SRS surgeons I could have chosen I would have expected a quality outcome from, but I made my choice upon my specific needs.
Cost is only one factor, and we only have one chance to get this right. Take your time, ask questions and shop around, and you should do well. Keep in mind, it's a complex surgical procedure, and as with any surgery, there aren't any real guarantees. Still, an experienced and reliable surgeon can tell you what you can reasonably expect. After the surgery, proper dilation and after care is essential.
