A Randomized, Double-Masked, Parallel-Group, Phenylephrine-Controlled Study of the Effect of OMS302 Added to Standard Irrigation Solution on Intraoperative Pupil Diameter and Acute Postoperative Pain in Children Ages Birth Through Three Years Undergoing Unilateral Cataract Extraction With or Without Lens Replacement

The purpose of this study is to evaluate the effect of OMS302 compared to phenylephrine when
administered in irrigation solution during cataract extraction on intraoperative pupil
diameter, acute postoperative pain, and safety in children birth through 3 years.

This study is a randomized, parallel-group, double-masked, phenylephrine-controlled study of
OMS302 in young children ages birth through three years undergoing unilateral cataract
extraction. Administration of test irrigation solutions will take place in a double-masked
fashion.

Intraoperative pupil size will be determined by measurement of pupil diameter from still
photos captured from video recordings of the procedure. Pupil diameter measurements will be
performed immediately prior to the initial incision and at one-minute intervals until the end
of the procedure (wound closure). Pain will be assessed by the Alder Hey Triage Pain Score.

Inclusion Criteria:

1. Are 0 through three years of age at the time of surgery.

2. Are to undergo unilateral primary cataract extraction with or without lens
replacement.

3. Have informed consent and Health Insurance Portability and Accountability Act (HIPAA)
Authorization provided by a parent or legal guardian in accordance with local
regulations and governing IRB/IEC requirements prior to any procedures or evaluations
performed specifically for the sole purpose of this study.

4. A parent or legal guardian has indicated that they understand and are able, willing,
and likely to fully comply with study procedures and restrictions.

Exclusion Criteria:

1. Corneal diameter less than nine millimeters in the study eye.

2. Hypersensitivity to phenylephrine, ketorolac, or other NSAIDs, including aspirin, or
latex.

3. Surgeon's expectation that the protocol-specified mydriatic regimen will not be
adequate to perform the procedure and that additional mydriatic treatment
(pharmacological or mechanical) will be required.

4. Presence of clinically significant gastrointestinal, cardiovascular, hepatic, renal,
hematological, endocrine, neurological, psychiatric, respiratory, or other medical
condition that could increase the risk to the subject as determined by the
Investigator.

5. Presence of active or suspected viral, bacterial, or fungal disease in the study eye.

6. Use of any topical medication in the study eye within seven days prior to surgery,
except for medications needed to examine the eye or prepare for surgery.

7. Have a post-traumatic cataract.

8. History of uveitis or evidence of past uveitis such as synechiae or keratic
precipitates in the study eye.

9. Have an ocular neoplasm in the study eye.

10. Have a clinically significant infection.

11. Have suspected permanent or low vision in the fellow non-study eye, unless caused by a
cataract. The study eye must not be the subject's only good eye.

12. Use of systemic corticosteroids or NSAIDs in the seven days prior to surgery.

13. Have a history of clinically significant corticosteroid-induced intraocular pressure
increase.

14. Use of any medication for ocular hypertension or glaucoma in the study eye.

15. Use of monoamine oxidase inhibitors for 21 days preoperatively.

16. Prior participation in a clinical study of OMS302.

17. Participating in any investigational drug or device trial within the 30 days prior to
the day of surgery.

18. History of intraocular non-laser surgery in the study eye within the three months
prior to the day of surgery, or intraocular laser surgery in the study eye within 30
days prior to the day of surgery.

19. Presence of any condition that the Investigator believes would put the subject at risk
or confound the interpretation of the study data.

20. Be a member of the immediate family of the Investigator or employees of the
investigative site. Immediate family is defined as the Investigator's or employees'
natural or legally adopted child (including a stepchild living in the Investigator's
household), or grandchild.
