Objective
Photorefractive Keratectomy (PRK) is a commonly performed corneal refractive surgery but has significant post-operative pain. Pain medications after PRK are typically opioid-acetaminophen combinations. Alternatives to opioid medication are worth consideration. Patients will receive PRK in each eye sequentially, using the cannabinoid or codeine/acetaminophen for one eye and the other treatment for the fellow eye two weeks later.
Details
Full study title | Randomized, Controlled Cross-over Comparison of Cannabidiol to Oral Opioid for Postoperative Photorefractive Keratectomy Pain Control |
Protocol number | OCR42790 |
ClinicalTrials.gov ID | NCT05477875 |
Phase | Phase 2 |
Eligibility
Inclusion Criteria:
Adults older than 18 years with refractive stability for 1 year electing to have PRK surgery
Consenting to participate
Not meeting exclusion criteria will be included in the study population.
Exclusion Criteria:
Patients not candidates for PRK will be excluded from the study.
Patients taking other pain medications for concomitant medical conditions including, but not limited to tricyclic antidepressants, gabapentin and tramadol will be excluded from the study.
Additional exclusion criteria will be known or suspected allergy or hypersensitivity to any of the routine or study medications.
Patients completing follow up appointments at anywhere other than UF Health Ophthalmology clinic at the Oaks will not be enrolled in the study.
Patients who are pregnant or nursing are not eligible for PRK, and such patients are not eligible to enroll in this study. Female patients of child-bearing age will be pregnancy tested before surgery and study enrollment.
Patients will be specifically counseled, and it will be noted in the written informed consent that use of the cannabinoid product may result in a positive THC urinalysis screening test so they may self-exclude if such a situation could cause social and/or employment conflict.
