3.       Revise your disclosure to show the potential impact of redemptions on
the per share value
         of the shares owned by non-redeeming shareholders by including a
sensitivity analysis
         showing a range of redemption scenarios, including minimum, maximum
and interim
         redemption levels.

that shareholders who
         elect not to redeem their shares may experience in connection with the
business
         combination. Provide disclosure of the impact of each significant
source of dilution,
         including the amount of equity held by founders, convertible
securities, including warrants
         retained by redeeming shareholders, at each of the redemption levels

         sensitivity analysis, including any needed assumptions.

underwriting fee on a
         percentage basis for shares at each redemption level presented in your
sensitivity analysis
         related to dilution.

8.       We note several statements that if your product candidates were
approved today, they
         would be the first and only such treatment for certain indications.
These statements
         are speculative and are inappropriate given the length of time and
uncertainty with respect
         to securing marketing approval. If your intention is to convey your
belief that your
         product candidates utilize a novel technology or approach, you may
discuss how your
         technology differs from technology used by competitors or that you are
not aware of
         competing products that are further along in the development process.
Statements such as
         these should be accompanied by cautionary language that the statements
are not intended

         to give any indication that your product candidates have been proven
effective or will
         receive regulatory approval.

9.       Please revise where appropriate to provide the data and assumptions
relied on for your
         estimated indication populations and estimated addressable market of
your product
         candidates for each indication.
10.      We note the inclusion of the glaucoma, geographic atrophy, diabetic
retinopathy, and
         neurotrophic keratitis indications for OCS-05, and the OCS-03 and
OCS-04 programs in
         your pipeline table on page 193. Please explain why each program is
sufficiently material
         to your business to warrant inclusion in your pipeline table and
revise to provide
         additional disclosure about these programs in your Business of Oculis
and Certain
         Information about Oculis section including, without limitation, the
current status of
         program development and future development plans. Alternatively,
remove the programs
         from your pipeline table.
11.      Given the early stage and lack of disclosure regarding the undisclosed
product candidate,
         please remove the undisclosed product candidate row from the pipeline
table.
12.      Please revise your statements on pages 194 and 204 that topical ocular
administration of
         OCS-02 showed efficacy as efficacy determinations are solely within
the authority of the
         FDA or similar regulatory body. You may provide a summary of the
objective data from
         your trials without including conclusions related to efficacy.
Similarly, please revise the
         statement on page 196 that you are conducting a Phase 3 clinical trial
of OCS-01 to
         "confirm its efficacy" in treating inflammation and pain following
ocular surgery
         and remove the reference to "positive" Phase 2 clinical trial results
achieved with OCS-
         01 in treating DME on page 201.
13.      We note your disclosure on page 82 that OCS-05 has been subject to a
clinical hold by the
         FDA since 2016. Please revise your discussion of OCS-05 on pages 193,
195 and 208, and
         your pipeline table to discuss the clinical hold and the steps that
you must take to clear the
         hold. Please also include in your discussion the fact that if you are
unable to clear the
         clinical hold, OCS-05 may not receive clearance from the FDA to
proceed with human
         clinical trials, may never receive regulatory approval from the FDA,
and you may be
         unable to market and commercialize OCS-05 in the United States.

General

23.      We note your disclosure that a number of financial institutions have
acted as advisors in
         connection with the Business Combination and PIPE Financing or as
underwriters for the
         EBAC SPAC IPO. We also note press reports that certain financial
advisors are ending
         their involvement in SPAC business combination transactions. Please
tell us, with a view
         to disclosure, whether you have received notice from any of the firms
advising on the
         business combination transaction about them ceasing involvement in
your transaction and
         how that may impact your deal or the deferred underwriting
compensation owed to such
         firms for the SPAC   s initial public offering.
24.      With a view toward disclosure, please tell us whether your sponsor is,
is controlled by, has
         any members who are, or has substantial ties with, a non-U.S. person.
Please also tell us
         whether anyone or any entity associated with or otherwise involved in
the transaction, is,
         is controlled by, or has substantial ties with a non-U.S. person. If
so, please revise your
         filing to include risk factor disclosure that addresses how this fact
could impact your
         ability to complete your initial business combination. For instance,
discuss the risk to
         investors that you may not be able to complete an initial business
combination with a
         target company should the transaction be subject to review by a U.S.
government entity,
         such as the Committee on Foreign Investment in the United States
(CFIUS), or ultimately
         prohibited. Further, disclose that the time necessary for government
review of the
         transaction or a decision to prohibit the transaction could prevent
you from completing an
         initial business combination and require you to liquidate. Disclose
the consequences of
         liquidation to investors, such as the losses of the investment
opportunity in a target
         company, any price appreciation in the combined company, and the
warrants, which
         would expire worthless.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

       Refer to Rules 460 and 461 regarding requests for acceleration. Please
allow adequate
time for us to review any amendment prior to the requested effective date of
the registration
statement.
