Well, yes, sure there is. I mean, again, I think, the utilization of the product, the number of vials we're selling indicates to us what is the demand and is that demand expanding. I think, again, if we come back to a more global view of how we view the progress of Omidria, how are we doing clinically? Well, when docs use this product, they like this product. So the clinical piece seems to be pretty well put to bed. So the question is reimbursement, reimbursement, reimbursement. And how do we help get the facilities comfortable that these procedures using Omidria will be reimbursed, the product will be reimbursed for use in their procedure. I think what we shared with you today is a pretty positive picture about the overall reimbursement efforts and the overall reimbursement success associated with Omidria. Clearly, that is going to be an area of focus for us. I mean, I think that as that level of confidence in reimbursement increases, I'd have to question what other impediment could there be. You have the only FDA-approved product. When you use it, you like the way it works. In fact, again, these are not controlled studies, but we've had the reports from so many clinicians coming back saying that they have reduced their use of these pupil, these mechanical pupil-expanding devices. In many cases, frankly eliminating them to date. Those cost money, those post risks to patients, they are problem. When you put these things all together, you start to think, "Gee, if that reimbursement piece -- if that confidence level is high, what should be the impediment?" And I'm sure there are some. But I think, overall, you've addressed the 2 large drivers. One is clinical and one is reimbursement. As I said, we think the clinical is pretty clear. And the more the docs learn about the product, frankly, the more they appreciate the clinical benefits. So it's really the reimbursement. And I think, we've helped, at least, I hope we've helped today clarify that situation.
