Sure, yes. So the issue with Change Healthcare has affected numerous companies, including us, that sell not only Part D as in David products, but also Part B is and Bravo products. So the system is still sort of being unclogged. And the Change Healthcare issue has affected payments to our customers from the government. And this has affected our sales temporarily in the first quarter, but we are seeing evidence of the systems beginning to be unclogged. We expect recovery and full normalization in the second quarter. But this is an issue, the cyber-attack that has affected us, but it has affected many, many companies who sell into the pharma market. In terms of retina, the reason why we went to CMS, and I talked about this in our last letter to stockholders is because there was uptake in the retina market. The retina market is in the form of the intravitreal injection market, specifically it is a very large market, exceeding 10 million unit opportunities per year. We saw uptake in that market. We were seeing reimbursement happen in that market around the country. But the market is unique and that it is highly concentrated. There are very large groups of potential buyers for these products. And so in the face of those sorts of opportunities in front of us, we thought it was prudent to confirm with CMS that, in fact, our J-code, which is a product-specific permanent J-code, would, in fact, be separately reimbursable in the physician's office setting. And so as we promised in the last letter to stockholders, we requested a meeting with CMS. We had that meeting on January 9th, and we have been waiting patiently to hear from them. As we said in the prepared remarks, we were added to the ASP file, the physicians ASP file recently, but we did not know whether or not that confirmed separate payment in the physician's office. And that happened just yesterday afternoon, which, as I said, is a very important event for the company. Our expectation now is that we will be able to, with this news, open up the market for intravitreal injections that can benefit from unique attributes of IHEEZO and that is going to start here very, very soon, and that it will significantly change, I think, the trajectory for IHEEZO and also, I think, for our company. But IHEEZO is a fantastic product for that application. It's also obviously used in numerous other ophthalmic interventions, and it's a very, very exciting opportunity for us.
