Summary:

      SURF-201 is being studied for the treatment of eye inflammation and pain in people who are
      undergoing cataract surgery. SURF-201 is an investigational drug (which means the study drug
      is currently being tested) in the form of a sterile eye drop.

      The purpose of this research study is to see how well SURF-201 works and what side effects
      there are, and to compare it with Vehicle (placebo). This study will involve about 80 study
      participants at several different research sites in the United States.
    

Eligibility criteria:

        Inclusion Criteria:

          1. Adult subjects age 18 years or older scheduled for uncomplicated unilateral cataract
             surgery with posterior chamber intraocular lens (IOL) implantation.

          2. Subjects must be able to understand and sign the Informed Consent Form (ICF).

          3. Female subjects of childbearing potential must agree to and submit a negative urine
             pregnancy test before any study-specific procedures are performed. The subjects must
             be using and continue to use a suitable method of contraception for the duration of

             injectable or implantable contraceptive, intrauterine device (IUD), abstinence or
             surgical sterilization of a partner. If a subject is not of childbearing potential
             (e.g., has been postmenopausal for at least 12 months or is premenarchal, or has
             undergone a hysterectomy, bilateral oophorectomy or a bilateral tubal ligation), a
             urine pregnancy test and use of a suitable method of contraception for the duration of
             the study will not be required.

          4. Subjects must have a best-corrected visual acuity (BCVA) of at least +1.0 log of the
             minimum angle of resolution (logMAR) (Snellen equivalent of 20/200) in the non-study
             eye (fellow eye).

          5. Subjects must have an intraocular pressure (IOP) of >8 mmHg and ≤22 mmHg in the study
             eye (surgery eye).

             instructions.

          8. Subjects must be able to self-instill the study drug (if unable, a caregiver must be
             available to instill all doses of the study drug).

             protocol).

        Exclusion Criteria:

             eye within the last 2 years prior to Screening which, in the investigator's opinion,
