Thank you, Nancy, and good morning, everyone. Before I begin, I want to reiterate what a productive quarter this has been for the EyePoint clinical team as we executed on multiple milestones, further advancing our innovative pipeline. Turning to our product pipeline, EYP-1901 is an investigational sustained release therapy using a bioerodible formulation of our Durasert technology with vorolanib, a tyrosine kinase inhibitor that binds the receptor, therefore blocking all isoforms of VEGF. Vorolanib's differentiated mechanism of action from the standard of care ligand blockers may provide additional benefits such as neuroprotection. Compared to other TKIs, vorolanib features reduced off target binding, leading to a potentially improved safety profile with no reported ocular toxicity. Durasert as a proven and safe sustained release delivery platform differentiates EYP-1901 from other agents targeting VEGF mediated retinal disease, as this bioerodible insert allows for true sustained release of the drug with zero order kinetics with up to nine months duration of activity. In wet AMD, EYP-1901 has been studied as a maintenance therapy following induction therapy with a standard of care anti-VEGF therapeutic, a new treatment paradigm which we call treat to maintain. Our goal is to sustain the majority of wet AMD patients treatment interval up to six months or longer with a single injection of EPY-1901. By providing the sustained delivery therapy, patients and practitioners can potentially have the flexibility to safely reduce the number of visits to their retina specialist through controlled and sustained intravitreal delivery of a differentiated anti-VEGF drug. Turning to non-proliferative diabetic retinopathy, or NPDR, it is a very common disease affecting almost one-third of diabetic adults over the age of 40, and it's projected to impact over 14 million Americans by 2050. In NPDR, blood vessels are weakened and this may lead to both swelling of the macula and abnormal blood vessel growth. If left unchecked, NPDR can be the harbinger of severe visual loss as well as other ocular complications. Because the currently approved therapies for NPDR require a significant visit and treatment burden, 97% of NPDR patients are currently observed. This provides a significant market opportunity for EYP-1901, which may be able to be effectively delivered at a nine-month interval or longer in NPDR. Revisiting the Phase 1 DAVIO clinical trial for EYP-1901, we recently reported positive 12 months safety and efficacy results at the American Academy of Ophthalmology Meeting in Chicago. The DAVIO trial enrolled 17 patients and each received a single intravitreal injection of EYP-1901 at one of four different dose levels. All enrolled patients were previously treated with standard of care anti-VEGF therapy. No reinjection with the study drug was performed during the trial and typical criteria for supplementation with a standard of care anti-VEGF was employed. We were pleased that the 12-month data featured no reports of ocular SAEs or drug-related systemic SAEs. No reported events of vitreous floaters, endophthalmitis, retinal detachment, insert migration to the anterior chamber, retinal vasculitis, posterior segment inflammation or retinal vascular occlusive events. Further, the 12-month follow-up confirmed stable best corrected visual acuity of minus 4.12 ETDRS letters and stable central subfield thickness on OCT of minus 2.76 microns. Interestingly, one-third of eyes were supplemental anti-VEGF free up to 12 months after a single injection of EYP-1901. Up to six months, 53% of eyes were supplement free. Additionally, there continued to be positive treatment burden reduction of 73% at 12 months compared to 75% at the six-month visit. On the heels of these positive data, we enrolled our first patients in two separate Phase 2 clinical trials of EYP1901, one for the treatment of wet age-related macular degeneration called DAVIO 2 and one studying the drug at non-proliferative diabetic retinopathy called the PAVIA study. The DAVIO 2 trial is expected to enroll approximately 150 wet AMD patients previously treated with a standard of care anti-VEGF therapy and randomly assigned to one of two doses of EYP-1901, approximately 2 milligrams or approximately 3 milligrams versus an on-label aflibercept control. EYP-1901 is delivered with a single intravitreal injection in the physician's office similar to current FDA approved anti-VEGF treatments. The primary efficacy endpoint of the DAVIO 2 trial is non-inferiority to the aflibercept control, as measured by change in best corrected visual acuity six months after the 1901 injection. Secondary efficacy endpoints include change in CST as measured by OCT, time to for supplemental anti-VEGF, reduction in treatment burden and safety. We look forward to progressing the DAVIO 2 trial and anticipate top line results in the fourth quarter of 2023. The first patient was dosed in the Phase 2 PAVIA clinical trial with EYP1901 for the treatment of NPDR in September of 2022. The trial was expected to enroll approximately 105 patients randomly assigned to one of two doses of EYP-1901, approximately 2 milligrams or approximately 3 milligrams or to the control group, which will receive a sham injection. In this trial as well, EYP-1901 is delivered with a single intravitreal injection in the physician's office. The primary efficacy endpoint of the trial was improvement of at least two diabetic retinopathy severity scale levels at week 36. Secondary endpoints include onset of vision threatening complications, occurrence of diabetic macular edema and/or proliferative disease, retinal ischemia, non-perfusion and safety. In summary, we are very proud of the clinically validating results we've seen from the Phase 1 trial with EYP-1901. And we are excited to provide updates on the DAVIO 2 and PAVIA trial in the quarters to come. I will now turn the call over to Scott Jones, Chief Commercial Officer, for the commercial update. Scott?
