EXPLANATORY NOTE

This Amendment No. 1 on Form 8-K/A amends the Current Report on Form 8-K filed on January 25, 2024 (the “Original 8-K”), to provide an updated version of the investor presentation furnished as Exhibit 99.1 thereto to update market size opportunity references and clarify the cost of an NDA filing for Apersure as set forth on slides 16, 17 and 28. The updated investor presentation is furnished as Exhibit 99.1 hereto and supersedes Exhibit 99.1 to the Original 8-K in its entirety. No other changes have been made to the Original 8-K or to Exhibit 99.1 furnished hereto.

Item 7.01. Regulation FD Disclosure.

On January 25, 2024, Eyenovia released an updated investor presentation, a copy of which is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Eyenovia is developing topical ophthalmic medications that utilize its novel, patented Optejet® drug-device dispensing platform to address large market indications with significant unmet medical needs. Numerous studies have demonstrated the ability of the Optejet to achieve efficacy with up to 80% less medication than traditional eye drops, resulting in increased local tolerability and decreased systemic exposure to both drug and preservatives. The Optejet technology is protected by a comprehensive IP portfolio, with many claims in effect beyond 2031.

Complementing its Optejet device, Eyenovia is developing its Optecare™ suite of digital applications which leverages the onboard programming and Bluetooth technology in the Optejet to track usage and boost compliance through reminders sent to the patient, which may result in improved patient outcomes. This also represents a potential additional revenue stream for eye doctors under a CPT code for “Remote Therapeutic Monitoring Treatment Management Services.”

Eyenovia currently has one commercial asset, Mydcombi for mydriasis (in-office and surgical pupil dilation), which is currently being launched commercially. Eyenovia estimates this to be a $250 million market annually, and the updated investor presentation contains several testimonials from early adopters of the technology. Mydcombi represents the first FDA approved drug in the Optejet, providing important validation of the technology.

Eyenovia in-licensed its second asset, APP13007 for pain and inflammation following ocular surgery, from Formosa Pharmaceuticals in August of 2023. APP13007 has an FDA PDUFA date of March 4, 2024. APP13007 utilizes Formosa’s APNT™ platform which reduces an active pharmaceutical ingredient’s particle size with high uniformity and purity, ultimately enhancing bioavailability.

New clinical data in the updated investor presentation demonstrates that 91% of APP13007-treated patients were pain free through day 15, as compared to 42% for placebo. Similarly, 59% of APP13007-tretaed patients were free from inflammation (ACC Grade 0) through day 15, versus 16% for placebo. Importantly, the clinical profile of APP13007 allows for 2x/day dosing in a market where most approved treatments require up to 4x/day dosing. APP13007 was well tolerated in clinical trials. Eyenovia plans to launch APP13007 in 2H 2024, if approved. This would allow the company to further leverage its planned 10-person field sales force.

In addition, Eyenovia recently announced that it has re-acquired the development rights to MicroPine (precision dosed atropine spray) from Bausch+Lomb, which is currently in Phase 3 for pediatric myopia. Myopia, which typically begins in early childhood, is characterized by an elongation of the eye, resulting in significant vision loss and even blindness if not treated. It is estimated that myopia affects 25 million children in the U.S. alone, with five million of those believed to be at high risk. The Review of Myopia Management states this equates to a $1.8 billion annual market opportunity in the U.S., with a similar opportunity in China. With myopia, treatment compliance is particularly important to slow disease progression, early indications from use of Eyenovia’s Optecare remote therapeutic monitoring suggest enhanced dosing compliance as compared to historical treatments without such monitoring.

In terms of remaining development steps for MicroPine, Eyenovia is planning to meet with FDA to discuss possible changes to the Phase 3 CHAPERONE clinical trial protocol to expedite development, including a possible interim analysis of data from ~300 patients in late 2024. If positive and statistically significant, Eyenovia plans to meet with FDA again with the goal of submitting an NDA in 2H 2026. If positive but not statistically significant, Eyenovia will continue the trial until the original enrollment target of 420 patients reaches the study endpoint. Under that scenario, the Company would plan to file an NDA in 2H 2027.

Longer term, the Company sees potential applications for the Optejet in glaucoma (annual U.S. market opportunity of $2.7 billion), acute dry eye ($236 million), chronic dry eye ($2.1 billion) and eye hydration.

4 Today’s Eyedropper Bottle Designed for manufacturing ease, not patient use Over the past 125 years, changes in eyedropper design have done little to improve the usability of topical ophthalmic medications 1800’s Glass Pipette 1900’s Glass Pipette with Bulb and Separate Vial Today Integrated Bottle with Dropper Tip 1. S urvey conducted in January 2023 with 100 people (19 - 65+ Age Range, Mean Age = 51YO) who regularly take eye drop medications. Respondents were asked to rank common drug forms from easiest to most difficult to administer on a 0 - 10 scale (0 meaning no difficulty, 10 meaning extremely difficult). Of the 11 medication types ra nked, eye drops were the third most difficult behind suppositories and eye ointments. The topical ointments were ranked the easiest to administer with an average score of 1.1, and suppositories ranked the most d iff icult with a score of 6.48. Eye drops received an average score of 4.6. In a recent survey conducted by J. Reckner and Associates, consumers reported that taking eye drops was among the most difficult ways to self - administer medication 1
