Thanks, Donald. The fourth quarter of 2022 was a tremendous success for Ocular Therapeutix and has set the stage for a very strong start to the year in 2023. First, on the sales side, we finished the quarter with DEXTENZA net product revenue sales of $13.9 million compared with the same quarter of previous year sales of $12.2 million and sales over prior quarter of $11.9 million. That represents growth of approximately 14% and 17%, respectively. Total DEXTENZA net product revenue was $50.5 million, representing growth over prior year of approximately 20%. Most importantly, in the fourth quarter, we regained in-market sales momentum and I'm pleased to report that this momentum has continued in the first couple of months this quarter. I will introduce you to our new Senior Vice President of Commercial in a few moments who will go through -- who will go over the reasons for the return to growth and our go-to-market strategy. While we were very pleased to regain momentum with DEXTENZA, we are really seeing the potential value of our pipeline continue to emerge, following the recent data we shared on OTX-TKI, our axitinib-containing hydrogel implant for the treatment of wet AMD and other VEGF-mediated retinal diseases. On February 11, Dr. Andrew Moshfeghi presented the interim 10-month results from our Phase I study in the U.S. where we compared a single dose of OTX-TKI to EYLEA given every 8 weeks in patients with wet AMD. The results were spectacular as we saw no additional rescues up to month 10 of the 73% of patients who were rescue-free up to month 7, demonstrating potential best-in-class durability. We believe the $15 billion global market for wet AMD and diabetic retinopathy is driven by durability. While these results mean a great deal to Ocular Therapeutix and its shareholders, more importantly, they suggest a better future for patients suffering from VEGF-mediated retinal diseases, such as wet AMD, diabetic retinopathy and diabetic macular edema. In the case of wet AMD, it is well known that the vision gained seen when starting anti-VEGF treatments are not maintained over time in the real world. The primary reason for this is the lack of compliance caused by the injection burden of current antibody therapies like LUCENTIS and EYLEA. In the real world, patients tend to miss necessary injections for a variety of reasons. Wet AMD patients are elderly and can find it difficult to get to retina offices on a 4 to 8 weekly basis, so appointments are missed or delayed and permanent vision loss occurs because of the damage caused when the medication wears off and the disease process return. In the case of diabetic retinopathy where patients are generally of working age, the lack of urgency, given that disease may not have yet manifested and finding the time to get treated on a frequent basis, create real compliance challenges. In this population, the current standard of care is watchful waiting and many patients frequently progress to more severe vision-destroying disease before seeking treatment, making the results -- the resulting diabetic macular edema, a leading cause of blindness among the working age population. In short, we believe the promise of a drug like OTX-TKI is not only about convenience but also about saving vision. If we can move durability from the current frequency of injections to at least 9 months and beyond, we believe we can keep people on treatment and maintain vision. Lastly, it is important to understand that OTX-TKI is a different paradigm than typical antibody treatments. Existing treatments, like LUCENTIS and EYLEA, are bolus injections where a large amount of antibodies, well above the amount needed for immediate efficacy, are injected into the vitreous that, over time, are eliminated from the vitreous until they drop below therapeutic levels, allowing the disease process to restart. They extend injection intervals by making the antibody larger and slower to eliminate or just by jamming more antibodies into the eye with each injection. Either way, you're still treating a chronic disease with pulsatile dosing. OTX-TKI is different. OTX-TKI is designed to deliver a continuous dose of axitinib, a potent inhibitor of VEGF, keeping drug concentrations above therapeutic levels for extended periods without the drug peaks and troughs of pulsatile dosing. We believe the results we recently shared bear this out and demonstrate that our hydrogel technology could allow us to maintain therapeutic levels of axitinib at continuous levels in the vitreous for durations of at least 10 months. This new paradigm would allow physicians and patients the comfort of knowing the drug is always onboard and can hopefully demonstrate that there's less variability in the retina over time and, more importantly, that vision gains from anti-VEGF therapy are maintained in the real world. So what's next? We believe we have our proof of concept for OTX-TKI in wet AMD and, by extension, had gone a long way toward proof-of-concept and other VEGF-mediated retinal disease. Importantly, we also have a working formulation. We believe we'll be ready to enter the first pivotal trial in wet AMD as soon as the third quarter of this year. We are in ongoing discussions with the FDA regarding pivotal study designs and are very encouraged by the potential path forward both in wet AMD and diabetic retinopathy. We have also mentioned that commencing this trial is subject to financing and we are considering a range of nondilutive or minimally dilutive funding options but we have strong preference and are seeking to go forward with a potential strategic alliance. We have also stated our intention to begin a Phase III program for diabetic retinopathy in the first quarter of 2024, assuming positive top line data results from our ongoing Phase I clinical trial in diabetic retinopathy. The diabetic retinopathy program is a separate program with much more modest resource requirements than wet AMD. And consequently, we believe we could secure funding on our own without necessarily having a strategic alliance in place for our wet AMD program. We do, however, recognize that a potential strategic interested in our wet AMD program would also likely be interested in our diabetic retinopathy program. Our current plan is to commence the first pivotal trial in diabetic retinopathy in Q1 2024. Net-net, we believe we have a very valuable asset in OTX-TKI with a strong plan moving forward. With that. Let me turn the call over to Steve Meyers, our new Senior Vice President, Commercial, to discuss more on DEXTENZA and our 2023 guidance.
