Ladies and Gentlemen:

We have acted as counsel to Kiora Pharmaceuticals, Inc., a Delaware corporation (the “Company”), in connection with the preparation of a Registration Statement on Form S-1 (Registration No. 333-264641) (the “Registration Statement”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), on May 3, 2022, as amended on July 12, 2022, July 19, 2022 and July 20, 2022, with respect to the offer and sale of (a) 20,707,832 shares (the “Common Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”), (b) 5,500 shares (the “Preferred Shares”) of the Company’s Series E Convertible Preferred Stock, par value $0.01 per share (the “Series E Preferred Stock”), which are convertible into an aggregate of 20,707,832 shares of the Company’s Common Stock (the “Conversion Shares”), (c) Class A Warrants (the “Class A Warrants”) to purchase an aggregate of 20,707,832 shares of Common Stock (the “Class A Warrant Shares”), and (d) Class B Warrants (the “Class B Warrants” and, collectively with the Class A Warrants, the “Warrants”) to purchase an aggregate of 20,707,832 shares of Common Stock (the “Class B Warrant Shares” and, collectively with the Class A Warrant Shares, the “Warrant Shares”). The Common Shares, Preferred Shares, Conversion Shares, Warrants and Warrant Shares are referred to herein collectively as the “Securities.”

The Securities are to be sold to the underwriter for resale to the public as described in the Registration Statement and pursuant to the underwriting agreement referred to in the Registration Statement (the “Underwriting Agreement”). We have assumed that the sale of the Securities by the Company and the exercise price of the Warrants will be at a price established by the Board of Directors of the Company or a duly-formed Pricing Committee thereof in accordance with the Delaware General Corporation Law that is at least the par value for each share of Common Stock being sold as part of the Securities and upon conversion of the Preferred Shares and exercise of the Warrants. We have also assumed that: (i) the Conversion Shares will be properly delivered to the persons electing to convert the Preferred Shares; (ii) the Warrant Shares will be properly delivered to the persons exercising the Warrants, and (iii) at the time of exercise of the Warrants, the consideration for the issuance and sale of the Common Stock in connection with such exercise is an amount that is not less than the par value of the Common Stock. With respect to the Conversion Shares and the Warrant Shares, we express no opinion to the extent that future issuances of securities of the Company, including the Conversion Shares and the Warrant Shares, may cause the Warrants to be exercisable for more shares of Common Stock than the number that then remain authorized but unissued and available for issuance.

In connection with this opinion, we have examined and relied upon the Registration Statement and the related prospectus, the Company’s Restated Certificate of Incorporation, as amended, the Company’s Second Amended and Restated By-Laws, the Underwriting Agreement, the Warrants, the form of Certificate of Designation designating the Series E Preferred Stock (the “Certificate of Designation”), and such instruments, documents, certificates and records that we have deemed relevant and necessary for the basis of our opinion hereinafter expressed. In such examination, we have assumed: (i) the authenticity of original documents and the genuineness of all signatures; (ii) the conformity to the originals of all documents submitted to us as copies; (iii) the truth, accuracy and completeness of the information, representations and warranties contained in the records, documents, instruments and certificates we have reviewed; and (iv) the due execution and delivery of all documents where due execution and delivery are a prerequisite to the effectiveness thereof.
