29, 2018, the Company raised aggregate net proceeds of approximately $24.5 million in connection with its initial public offering
(&ldquo;IPO&rdquo;). See Note 7 &ndash; Stockholders&rsquo; Equity &ndash; Initial Public Offering for additional details.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Company believes its current cash on
hand is sufficient to meet its operating and capital requirements for at least the next twelve months from the date these financial
statements are issued. Thereafter, the Company may need to raise further capital, through the sale of additional equity or debt
securities, to support its future operations. The Company&rsquo;s operating needs include the planned costs to operate its business,
including amounts required to fund working capital and capital expenditures. The Company&rsquo;s future capital requirements and
the adequacy of its available funds will depend on many factors, including the Company&rsquo;s ability to successfully commercialize
its products and services, competing technological and market developments, and the need to enter into collaborations with other
companies or acquire other companies or technologies to enhance or complement our product and service offerings. If the Company
is unable to secure additional capital, it may be required to curtail its research and development initiatives and take additional
measures to reduce costs in order to conserve its cash.</P>

ASU 2017-09 provides clarity on the accounting for modifications of stock-based awards. ASU 2017-09 requires adoption on a prospective

biopharmaceutical company developing a pipeline of ophthalmology products utilizing our patented piezo-print technology to deliver
micro-doses (6&ndash;8 &micro;L) of active pharmaceutical ingredients, or micro-therapeutics, topically to the eye. This micro-dosing
technology has the potential to replace traditional macro-dosing applications (e.g. conventional eye droppers) that routinely overdose
or under-dose when used in the topical administration of ophthalmic therapeutics. We believe our micro-therapeutic product candidates
may be able to achieve similar pharmacologic effects as traditional macro-dosing applications while reducing the adverse effects
associated with these techniques. We have received written FDA feedback indicating that we can proceed to Phase&nbsp;III clinical
trials for two of our lead&nbsp;programs: MicroProst, a novel micro-therapeutic latanoprost formulation for CACG, an indication
with no FDA-approved drug treatments; and MicroStat, a fixed combination of micro-therapeutic phenylephrine-tropicamide formulation
for mydriasis, also known as pupil dilation for use in eye exams. MicroTears, our OTC product candidate for dry eye, will not require

Phase&nbsp;II clinical trials, treating more than 110 subjects, with results published in peer-reviewed literature. Applying multiple
front-of-the-eye (the area in front of the lens) formulations in subjects for mydriasis, our piezo-print technology delivered microliter
precision at the volume of the eye&rsquo;s natural tear film capacity of 6&ndash;8 &micro;L, which reduced ocular and systemic
drug and preservative exposure when compared to eye drops, resulting in comparable efficacy with fewer side effects. We believe
that these clinical trials support our advancement into late stage clinical trials utilizing the 505(b)(2) pathway. We intend to
use this pathway for future clinical trials in new indications with significant unmet needs. We plan to commence clinical trials
for MicroProst and MicroStat in the second half of 2018, pending IND submission and FDA feedback.</P>

the Company will need to raise further capital, through the sale of additional equity or debt securities, to support its future

of the design and operation of our disclosure controls and procedures (as defined in the Exchange Act Rules 13a-15(e) and 15d-15(e))
(the &ldquo;Exchange Act&rdquo;). Based on the foregoing evaluation, our principal executive officer and principal financial and
accounting officer concluded that, as of March 31, 2018, our disclosure controls and procedures were not effective to provide reasonable
assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded,
processed, summarized, and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated
to our management, including our principal executive officer, as appropriate, to allow timely decisions regarding required disclosure.</P>

(&amp;#8220;Corinthian&amp;#8221;). A shareholder of Corinthian, alleging a fraudulent transfer, is seeking to recover the purchase price of its Corinthian shares and other damages in aggregate amount of approximately $&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;1.1&lt;/font&gt; million. The parties are not close to agreement on a settlement, and although further discussions may occur, the parties are prepared to proceed to trial. The court conducted a pretrial conference on January 22, 2018 and entered a final pretrial order on January 23, 2018. The order provided, among other things, for a final pretrial conference to be conducted on August 15, 2018 to address objections to expert witnesses&amp;#8217; opinions and testimony, with objections to be submitted by July 18, 2018 and responses by August 1, 2018. Trial briefs, requests for jury instructions, and proposed voir dire questions are due on August 30, 2018. The trial is scheduled for September 10, 2018. The Company is indemnified by Corinthian and Corinthian&amp;#8217;s applicable insurance policy provides coverage of $&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;10&lt;/font&gt; million, such that the Company does not expect to incur a material loss as a result of this litigation and, as a result, did not record a loss contingency as of March 31, 2018 or December 31, 2017, respectively.&lt;/div&gt; &lt;/div&gt;&lt;table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

At March 31, 2018, the Company&amp;#8217;s working capital and accumulated deficit were $&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;26,836,810&lt;/font&gt; and $&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;22,690,793&lt;/font&gt;, respectively. The Company has not yet generated revenues or achieved profitability and it is expected that its research and development and general and administrative expenses will continue to increase and, as a result, the Company will eventually need to generate significant product revenues to achieve profitability. On January 29, 2018, the Company raised aggregate net proceeds of approximately $&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;24.5&lt;/font&gt; million in connection with its initial public offering (&amp;#8220;IPO&amp;#8221;).

Thereafter, the Company may need to raise further capital, through the sale of additional equity or debt securities, to support its future operations. The Company&amp;#8217;s operating needs include the planned costs to operate its business, including amounts required to fund working capital and capital expenditures. The Company&amp;#8217;s future capital requirements and the adequacy of its available funds will depend on many factors, including the Company&amp;#8217;s ability to successfully commercialize its products and services, competing technological and market developments, and the need to enter into collaborations with other companies or acquire other companies or technologies to enhance or complement our product and service offerings. If the Company is unable to secure additional capital, it may be required to curtail its research and development initiatives and take additional measures to reduce costs in order to conserve its cash.&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;&lt;/font&gt;&lt;/div&gt; &lt;div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0px; FONT: 10pt Times New Roman, Times, Serif; font-size-adjust: none; font-stretch: normal" align="justify"&gt;&amp;#160;&lt;/div&gt; &lt;div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0px; FONT: 10pt Times New Roman, Times, Serif; font-size-adjust: none; font-stretch: normal" align="justify"&gt;&lt;u&gt;&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt; &lt;/font&gt;Cash&lt;/u&gt;&lt;/div&gt; &lt;div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0px; FONT: 10pt Times New Roman, Times, Serif; font-size-adjust: none; font-stretch: normal" align="justify"&gt;&amp;#160;&lt;/div&gt; &lt;div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0px; FONT: 10pt Times New Roman, Times, Serif; font-size-adjust: none; font-stretch: normal" align="justify"&gt;The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents in the financial statements.

For the three months ended March 31, 2018 and December 31, 2017, the Company had cash balances in excess of FDIC insurance limits of $&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;27,352,069&lt;/font&gt; and $&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;4,999,511&lt;/font&gt;, respectively.&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;&lt;/font&gt;&lt;/div&gt; &lt;div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0px; FONT: 10pt Times New Roman, Times, Serif; font-size-adjust: none; font-stretch: normal" align="justify"&gt;&amp;#160;&lt;/div&gt; &lt;u&gt;&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;&lt;/font&gt;Net Loss Per Common Share&lt;/u&gt;&lt;/div&gt; &lt;div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0px; FONT: 10pt Times New Roman, Times, Serif; font-size-adjust: none; font-stretch: normal" align="justify"&gt;&amp;#160;&lt;/div&gt; &lt;div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0px; FONT: 10pt Times New Roman, Times, Serif; font-size-adjust: none; font-stretch: normal" align="justify"&gt;Basic net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period.

At March 31, 2018, the Company&amp;#8217;s working capital and accumulated deficit were $&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;26,836,810&lt;/font&gt; and $&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;22,690,793&lt;/font&gt;, respectively. The Company has not yet generated revenues or achieved profitability and it is expected that its research and development and general and administrative expenses will continue to increase and, as a result, the Company will eventually need to generate significant product revenues to achieve profitability. On January 29, 2018, the Company raised aggregate net proceeds of approximately $&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;24.5&lt;/font&gt; million in connection with its initial public offering (&amp;#8220;IPO&amp;#8221;).

Thereafter, the Company may need to raise further capital, through the sale of additional equity or debt securities, to support its future operations. The Company&amp;#8217;s operating needs include the planned costs to operate its business, including amounts required to fund working capital and capital expenditures. The Company&amp;#8217;s future capital requirements and the adequacy of its available funds will depend on many factors, including the Company&amp;#8217;s ability to successfully commercialize its products and services, competing technological and market developments, and the need to enter into collaborations with other companies or acquire other companies or technologies to enhance or complement our product and service offerings. If the Company is unable to secure additional capital, it may be required to curtail its research and development initiatives and take additional measures to reduce costs in order to conserve its cash.&lt;font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"&gt;&lt;/font&gt;&lt;/div&gt; &lt;/div&gt;&lt;table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;</eyen:LiquidityAndFinancialConditionPolicyTextBlock>

(&#8220;ASU 2017-09&#8221;). ASU 2017-09 provides clarity on the accounting for modifications of stock-based awards. ASU 2017-09 requires adoption on a prospective basis in the annual and interim periods for our fiscal year ending after December 15, 2017 for share-based payment awards modified on or after the adoption date. This standard was adopted on January 1, 2018 and did not have a material impact on the Company&#8217;s financial position, results of operations or cash flows.</div> </div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table><span></span>

The agreement shall continue in full force and effect, on a country-by-country basis, until the latest to occur of: (i) the tenth (10th) anniversary of the first commercial sale of a micro-dose product candidate in Asia; or (ii) the expiration of the licensed patents. As of the date                         of this filing                    , there had been no commercial sales of a micro-dose product candidate in Asia, such that no royalties had been earned. Senju is owned by the family of a member of the Company&#8217;s Board of Directors and both beneficially own greater than 5% of the Company&#8217;s common stock.            </div>        </div>        <table >            <tr>                <td>                </td>            </tr>        </table><span></span>

The Company has not yet generated revenues or achieved profitability and it is expected that its research and development and general and administrative expenses will continue to increase and, as a result, the Company will eventually need to generate significant product revenues to achieve profitability. On January 29, 2018, the Company raised aggregate net proceeds of approximately $<font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt">24.5</font> million in connection with its initial public offering (&#8220;IPO&#8221;).

Thereafter, the Company may need to raise further capital, through the sale of additional equity or debt securities, to support its future operations. The Company&#8217;s operating needs include the planned costs to operate its business, including amounts required to fund working capital and capital expenditures. The Company&#8217;s future capital requirements and the adequacy of its available funds will depend on many factors, including the Company&#8217;s ability to successfully commercialize its products and services, competing technological and market developments, and the need to enter into collaborations with other companies or acquire other companies or technologies to enhance or complement our product and service offerings. If the Company is unable to secure additional capital, it may be required to curtail its research and development initiatives and take additional measures to reduce costs in order to conserve its cash.<font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt"></font></div> </div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table><span></span>

ASU 2017-09 provides clarity on the accounting for modifications of stock-based awards.
