Thank you, Lisa and thank you all for joining our call this afternoon. We made significant progress with our Orion program since the last investor call and our confidence in creating artificial vision via cortical stimulation continues to grow. Before reviewing the exciting details of Orion, let's review what happened in Q2 with our Argus business. We completed 17 Argus II implants during the quarter resulting in $1.9 million of revenue. This was disappointing given the momentum we were experiencing in Q2 when we held the last investor call. John will provide more details later. On the U.S. reimbursement front, we were pleased with the 2019 preliminary Medicare average outpatient payment rate of approximately $137,500 for Argus and the associated surgical procedure proposed by CMS on July 25. We were also happy to see CMS propose a new methodology for setting the rate for extremely low volume procedures that considers up to four years of data for devices such as Argus. We feel this new methodology will provide more stability in reimbursement rates for low volume devices and we will provide comments to CMS in the coming months and look forward to a final ruling later this year. We continue to have a dialogue with the FDA concerning a label expansion in the U.S. to include better vision RP patients. At this point, I believe additional clinical data will be required by the agency to support the expansion of our label. Our U.S. patient database now totals 165 clinical coordinator cleared patients, which is basically flat from our last update. We continue to be excited about this database and recently changed our focus for the remainder of 2018 to moving qualified candidates through the funnel. In fact, 7 of 9 patients implanted in the U.S. during Q2 were from our database. Finally, our next gen externals, named Argus II-S, should start clinical validating testing this quarter. As a reminder, the Argus II-S features a new CPU and new eyewear, including a camera. In addition to being a more powerful and upgradable platform, the Argus II-S is designed to be more comfortable and aesthetically pleasing. After completing clinical validation work at several U.S. locations, we expect to proceed with regulatory filings later this year. We believe the Argus II-S clinical validation and subsequent launch should be met with much enthusiasm amongst implanting centers and Argus users, and potentially inspire patients currently weighing when they will go ahead with the procedure, including those patients in our database. I'd like to now update you on our progress with Orion. At the end of May, we completed enrollment in our initial feasibility study with the fifth subject ahead of schedule. You'll recall that we were working with teams at UCLA in Los Angeles and Baylor in Houston to implant and test subjects. Since 4 of our five subjects were implanted at UCLA, we submitted a request and received approval from the FDA to enroll a 6th subject at Baylor. Baylor is actively screening subjects and we expect the sixth subject to be implanted soon. We are diligently gathering clinical data to evaluate safety and efficacy of this breakthrough technology. All subjects are very enthusiastic about the technology and their participation I this trial. The first five subjects all have their devices activated and report seeing spots of light on virtually all electrodes. The creation of spatial maps is at various stages for the subjects and we have progressed to using real-time video input with 4 out of 5 subjects. One subject is very close to being cleared for home use, meaning they can start using the system at home without supervision. Observations from our early testing include the following. Stimulation parameters are within expected ranges and are generally stable over time. Spatial maps vary by subject and are generally stable over time. As a reminder, spatial maps established the relationship between electrodes and where the subject sees a spot of light in their visual field when that electrode is activated. The field of view appears to be larger than Argus. Several subjects are undergoing directional motion testing. In this testing, subjects identify the direction of motion of various lines on a computer screen. Early test results are very encouraging. Finally, device reliability has been good as has device performance. On the safety front, we have experienced one serious adverse event, or SAE. One subject experienced a seizure while in the clinic when we were evaluating a specific video stimulation algorithm. The seizure resolved quickly and the subject was released from the clinic without need for hospitalization. Seizures are listed as an anticipated adverse event in the clinical protocol and the subject was allowed to continue participating in the study after the event was reviewed by a safety committee for the study and a committee at the implanting institution. The safety of our subjects is our top priority and we will continue to monitor each subject closely. Looking forward, we will soon start deploying representatives from our U.S. vision rehabilitation team to work with the Orion subjects in order to optimize the potential benefits in and around their home. This is a critical step to educate the subjects on how to use and interpret the system in their daily life. In the coming months, we will gather much more data and begin understanding what level of vision we can ultimately provide with the first gen Orion system. I look forward to providing updates as appropriate. Our discussions with the FDA are proceeding nicely. As discussed in past calls, Orion is part of the expedited access pathway program, also referred to as the breakthrough device program. Our interactions with the FDA have been productive with very timely feedback or responses. We will provide more details on our expected commercialization timeline in upcoming calls as the certainty around the clinical and regulatory pathway increases. Last year, we engaged a third party firm to help us assess the U.S. market potential for Orion. As expected, the market research suggests a robust market opportunity for Orion with over 500,000 individuals in the U.S. who are legally blind due to glaucoma, diabetic retinopathy, optic nerve disease, and eye trauma. The research estimates a potential U.S. addressable market of more than 70,000 individuals from this population with vision defined as bare light or no light perception. Again, this is only U.S. data and does not include patient populations in other regions of the world. Moreover, at this stage of our analysis, the largest segment of the market appears to be the eye trauma population. Those experiencing trauma tend to be younger, with an average age in their 30s, and are not generally impacted by additional medical conditions that may limit their lifespan, as is the case with many older patients. These patients would represent a significantly larger and younger population than Argus, who could potentially benefit from the Orion technology over the course of their lives. Based on these third party estimates, and utilizing conservative pricing assumptions, we believe the market for Orion is potentially a multibillion dollar opportunity. In the process of conducting the Orion market research, we also gained some valuable insights on the RP market. The research estimates approximately 1,500 patients in the U.S. with advanced RP that could be treated with the Argus II given the eligibility criteria of our label. Prior to this research, there had been no published market data indicating the actual number of RP patients in the U.S. whose vision loss had progressed to bare light perception or worse. The market research also validated our believe that expanding our label in the U.S. to treat better vision individuals could expand the treatable population by three to five times the current population. Next, I'd like to highlight some exciting research we are conducting internally or in some cases, in conjunction with research partners. These projects are still in the research phase, but we believe some efforts may become very important as we start treating large patient populations. First, we have advanced efforts with our partner to develop and implement eye tracking technology with Argus and eventually, Orion. This technology enables us to move the implant field of view in conjunction with the movement of the user's eyes. This is important because the brain expects to see the objects in a different relative location when your eyes move. If a user's eyes move but the view from the Argus camera does not, a distortion is created. This technology would minimize or eliminate this distortion by helping the brain better integrate the visual information, thus improving the stability and quality of the vision provided. Second, we are working with a partner to integrate thermal imaging technology with our systems and provide users with another option to create salient stimulation. Infrared imaging would allow users to visualize warm objects and could be especially useful in determining where people are in a room, regardless of lighting conditions. Third, we're developing depth based de-cluttering capabilities with a partner. In short, this technology would allow users to filter out objects further than a defined distance. This eliminates excess stimulation from distant and possibly distracting objects so that the user can more easily focus on and identify objects of interest. Fourth, we have a research project with a partner to develop customized object and facial recognition capabilities that will allow users to get additional auditory and/or haptic information integrated with the vision provided by their artificial vision system. This system also highlights the region in visual space where the object is located to allow the patient to accurately reach out and grasp or touch the object. For example, a patient using Argus or eventually Orion, looking at a phone, would hear the word phone, or when looking at another individual would hear that person's name. As you know, this is a rapidly developing technology and we see great potential to integrate with artificial vision. Finally, we have several additional efforts underway internally. One effort has been discussed several times in past calls and that is our continuing work to develop and evaluate various new stimulation strategies to improve the acuity of the vision provided. Another effort early in evaluation is the use of virtual reality in the artificial vision rehab process. We think this technology could increase engagement and usage during the rehab process and improve outcomes. To be clear, these projects are still in the research phase and there's no assurance of moving to development or commercialization. With that being said, we believe that many of these technologies have great potential to improve the quality or usefulness of the artificial vision we provide, or in some cases, act as a complementary technology that significantly improves the overall user experience. All of the technologies described above would benefit Argus users as well as Orion users. Before turning the call over to John, I'd like to speak to our focus and priorities moving forward. First, given the Orion market size, as well as our continued progress and confidence, Orion clinical and R&D efforts will remain the top priority for Second Sight. We are convinced a huge opportunity is in front of us and are committed to advancing the Orion technology with the necessary resources. Second, given the continued challenges we have faced in the limited RP market, we made the decision to maximize capital efficiency with our Argus commercial and clinical activities. We think this is prudent given the need to apply maximum resources to our Orion clinical and R&D programs. Some implications of this strategy to our Argus business include a higher bar for entering new Argus markets or expanding geographically. In other words, we need to be convinced of a short-term financial payback and increased focus on our strongest markets and the top centers of excellence in those markets allowing for more efficient deployment of field resources and the continuation of our efforts to expand the U.S. label to include better vision RP patients without conducting a potentially costly U.S. IDE trial. Third, we will continue advancing the exciting research projects described earlier. As the research progresses, we will prioritize the technologies, which hold the most promise and start moving them toward development and clinical evaluation. In closing, the goal of treating all forms of blindness with cortical stimulation has been a priority for the company since before the IPO. We now see an incredible opportunity ahead to transform the company as our confidence in the breakthrough Orion technology grows and the huge market opportunity materializes. I want to thank my talented coworkers at Second Sight for the hard work and dedication and our shareholders for the continued support. With that, I'd like to now turn the call over to John to review our second quarter financial results. John?
