Effect of Topical Fluoroquinolones on Epithelial Wound Healing After PRK
22 participantsStarted 2007-01
Plain-language summary
The prescribed antibiotic for prophylaxis of infection following PRK should be effective at eradicating a potential infection. In addition, the antibiotic should have a rapid onset of action, effectively penetrate the target tissue, and be safe and not toxic to any layer of the healing cornea, especially the epithelium. Several studies have investigated the toxicity of the fourth generation fluoroquinolones on the corneal epithelium and studies have demonstrated that gatifloxacin is less deleterious to the healing cornea than moxifloxacin. Most of these studies, however, have been conducted in animals. This was a retrospective chart review.

Inclusion Criteria:
* Patients were eligible for inclusion if they were a healthy male or female 18 years of age or older and were candidates for bilateral PRK.
* Eligible patients had a best-corrected Early Treatment of Diabetic Retinopathy Study (ETDRS) visual acuity score equivalent to a Snellen score of 20/30 or better in each eye, had a stable prescription for 1 year, were willing to participate in the study, and were able to comprehend and sign the informed consent form.
* All subjects were instructed that if they decide not to participate they could withdraw from the study at any time.
Exclusion Criteria:
* Patients were excluded from the study if they had a history of refractive or other ocular surgery in either eye.
* Patients with any condition which could delay wound healing were not eligible to participate.
* They were excluded if they had poor tolerance to any component of the masked study fluoroquinolones, Acular® LS (Allergan) or Pred Forte® (Allergan).
* Patients were also excluded if they required the use of a systemic antibiotic during the study period, were involved in another investigational study or had participated in a study within 30 days prior to the start of this study.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
