Epithelial Healing and Visual Outcomes of Patients Using Omega-3 Supplements as an Adjunct Therapy Before and After Photorefractive Keratectomy (PRK) Surgery
Abstract
The purpose of this study is to demonstrate that omega-3 supplement can be use as an adjunct therapy for PRK patients. The investigators believe that omega-3 supplement will reduce the size of persistent epithelial defects (PEDS) and eventually hasten the corneal reepithelialization after PRK surgery. If the outcome of this study proves to be effective, then PRK would be a more attractive option to those seeking refractive treatment.
Conditions: Refractive Error.
Primary outcome: Visual acuity, tear break up time, and corneal uptake will be assessed. Photographs will be taken. Calculation of the area in diameter will be assessed using Adobe Photoshop. Comparisons between each group will be made..
Enrollment: 17 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 17 participants or records.
