Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Prospective Open-label Interventional Study Randomized, self-controlled design in which one eye (Group A) receives Dextenza and the second eye (Group B) receives prednisolone acetate 1% QID 1 week, BID 1 week following bilateral PRK surgery. All eyes will receive topical moxifloxacin QID for one week. Moxifloxacin in used post-op regardless of the research. Post-operative evaluations to be performed on Day 3 and Day 4, Month 1, and Month 3. Phone call survey to be performed on Week 2.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Study Population

All patients enrolled had elected to undergo same-day bilateral PRK procedure at a single-site.

Description

Inclusion Criteria:

  • 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

Exclusion Criteria:

  • 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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Group A Dextenza
Will receive Dextenza post-operative
Drug: Dextenza 0.4Mg Ophthalmic Insert
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.
Active Comparator: Group B Topical Prednisolone
Will receive standard of care prednisolone acetate 1% QID for 1 week, BID for 1 week
Drug: Topical Prednisolone
Standard of care topical drop treatment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Patient Preference
Time Frame: Through Month 1 (Day 28 +/- 3 days)
Primary outcome of patient reference of dexamethasone insert versus topical steroid as measured by adapted Comparison of Ophthalmic Medications for Tolerability (COMToL) questionnaire.
Through Month 1 (Day 28 +/- 3 days)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Eyes Epithelialized at Day 3
Time Frame: Post-Operative Day 3
The percentage of eyes with fully healed epithelium at post-op day 3
Post-Operative Day 3

Postoperative Day 4
Mean Pain Score Per Eye (Group A: Dextenza vs. Group B: Topical Steroid)
Time Frame: Day 3
Pain score as measured by the Numerical Rating Scale (NRS) at day 3 post-operative. The rating scale is from 0-10 with 0 being no pain and 10 being severe pain.
