Outcome Measures
Primary Outcomes (1)
Patient Preference

Secondary Outcomes (6)
Percentage of Eyes Epithelialized at Day 3
Post-Operative Day 3
Percentage of Eyes Fully Epithelialized at Day 4 Postoperative
Postoperative Day 4
Mean Pain Score Per Eye (Group A: Dextenza vs. Group B: Topical Steroid)
Day 3
SPEED Questionnaire Results at Baseline and Postoperative Day 28
Pre-op Visit and Month 1 (Day 28)
Uncorrected Distance Visual Acuity
Month 1 and Month 3.
- +1 more secondary outcomes
Study Arms (2)
Group A Dextenza
EXPERIMENTALWill receive Dextenza post-operative
Group B Topical Prednisolone
ACTIVE COMPARATORWill receive standard of care prednisolone acetate 1% QID for 1 week, BID for 1 week
Interventions
The insert, containing 0.4 mg of active pharmaceutical product, is placed within the canaliculus to provide a sustained and tapered delivery of drug to the ocular surface over 30 days after a one-time insertion. The attributes of the insert reduce the risks for improper corticosteroid tapering and unwanted peaks and troughs in drug concentration.
Eligibility Criteria
You may qualify if:
- Any adult patient who is planned to undergo bilateral PRK surgery.
- Willing and able to comply with clinic visits and study related procedures
- Willing and able to sign the informed consent form
You may not qualify if:
- Patients under the age of 18.
- Patients who are pregnant (must be ruled out in women of child-bearing age with pregnancy test).
- Active infectious ocular or systemic disease.
- Patients with active infectious ocular or extraocular disease.
- Patients actively treated with local or systemic immunosuppression including systemic corticosteroids.
- Patients with known hypersensitivity to Dexamethasone.
- Patients with severe disease that warrants critical attention, deemed unsafe for the study by the investigator.
- Patients with a history of ocular inflammation or macular edema.
- Patients with allergy or inability to receive intracameral antibiotic.
- Patients on systemic non-steroidal anti-inflammatory drugs (NSAID) greater than 1,200 mg/day
- Patients with a corticosteroid implant (i.e. Ozurdex).
- Patient with corneal pathology which pre-disposes them to unsatisfactory outcomes.
- Patients who do not have 20/20 snellen visual acuity potential pre-operatively.
- MRSE greater than 6 diopters.
- Greater than 2 diopters anisometropia.
