faster than the blink reflex to help ensure instillation success. The precise delivery of a low-volume columnar spray by the Optejet® device minimizes contamination with a non-protruding nozzle and self-closing shutter. In clinical trials, the Optejet® has demonstrated that its targeted delivery achieves a high rate of successful administration, with 98% of sprays being accurately delivered upon first attempt compared to the established rate reported with traditional eye drops of ~ 50%.
A more physiologically appropriate volume of medication in the range of seven to nine microliters is delivered by the Optejet, which is approximately one fifth of the 35 to 50 microliter dose typically delivered in a single eye drop. Lower volume of medication exposes the ocular surface to less active ingredient and preservatives, potentially reducing ocular stress and surface damage and improving tolerability. The lower volume also minimizes the potential for drug to enter systemic circulation, with the goal of avoiding some common side effects that are related to overdosing of the eye.
We are developing versions of the Optejet with on-board digital technology to provide reminders via Bluetooth to smart devices and date and time stamp device use. This information can then be used by practitioners and health care systems to measure treatment compliance and improve medical decision making. In this way, the Optejet could serve as an extension of the physician’s office by providing information that is not currently possible to collect except through the use of diaries.
Our drug-device product line includes Mydcombi™ (tropicamide and phenylephrine HCL ophthalmic spray) and therapeutic programs MicroPine (atropine ophthalmic spray) and MicroLine (pilocarpine ophthalmic spray). MicroPine is our first-in-class topical therapy for the treatment of progressive myopia, a back-of-the-eye ocular disease associated with pathologic axial elongation and sclero-retinal stretching. In the United States, myopia is estimated to affect approximately 25 million children, with up to five million considered to be at high risk for progressive myopia. In February 2019, the FDA accepted our IND to initiate the CHAPERONE study to reduce the progression of myopia in children. The first patient was enrolled in the CHAPERONE study in June 2019.
On October 9, 2020, we entered into the Bausch License Agreement with B+L, pursuant to which B+L may develop and commercialize MicroPine in the United States and Canada. Under the terms of the Bausch License Agreement, we received an upfront payment of $10.0 million and we may receive up to a total of $35.0 million in additional payments, based on the achievement of certain regulatory and launch-based milestones. B+L also will pay royalties to Eyenovia on a tiered basis (ranging from mid-single digit to mid-teen percentages) on gross profits from sales of MicroPine in the United States and Canada, subject to certain adjustments. Under the terms of the Bausch License Agreement, B+L assumed sponsorship of the IND as well as ownership and the costs related to the ongoing CHAPERONE study.
We have also successfully expanded our manufacturing capabilities through a partnership with Coastline International, Inc. located in Tijuana, Mexico, and the construction of our own fill and finish facility in Redwood City, California. As of the date of filing, we are up-to-date supplying clinical product for the CHAPERONE and VISION Studies.
MicroLine is our investigational pharmacologic treatment for presbyopia. Presbyopia is a non-preventable, age-related hardening of the lens, which causes the gradual loss of the eye’s ability to focus on near objects and impairs near visual acuity. Allergan recently launched Vuity™, a pilocarpine drug product for the treatment of presbyopia. Our second Phase III study, VISION-2, used the same drug, delivered with the advantages of our Optejet® device. We released positive top-line results from VISION-2 in the fourth quarter of 2022.
Mydcombi™ is our fixed combination formulation of tropicamide-phenylephrine for inducing mydriasis for diagnostic procedures and in conditions where short term pupil dilation is desired. Mydcombi is a novel approach for the over 106 million office-based comprehensive and diabetic eye exams performed every year in the United States. As the only FDA-approved fixed combination of the two leading mydriatic agents in the United States and as an ophthalmic spray, Mydcombi may present a number of benefits for the optometric and ophthalmic offices as well as patients. Those benefits may include better tolerability, more efficient use of office time and resources, and an overall improved doctor-patient experience. As noted above in Recent Development, we received FDA approval on May 5, 2023, and are preparing to commercialize the product starting with a targeted launch and expanding in 2024 when we expect our internal manufacturing capabilities to come on-line.
On August 10, 2020, we entered into the Arctic Vision License Agreement with Arctic Vision, which was amended on September 14, 2021, pursuant to which Arctic Vision may develop and commercialize MicroPine, MicroLine and Mydcombi in Greater China (mainland China, Hong Kong, Macau and Taiwan) and South Korea. Under the terms of the Arctic Vision License Agreement, as amended, we received an upfront payment of $4.25 million before any payments to Senju Pharmaceutical Co., Ltd. (“Senju”). In addition, we may receive up to a total of $39.7 million in additional payments, based on various development and regulatory milestones,
