Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a randomized, double-masked, placebo-controlled study to determine the safety of pAF in patients who undergo PRK.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Photorefractive Keratectomy (PRK) is a common elective surgery used to correct refractive errors. We propose that amniotic fluid drops may be beneficial in promoting ocular surface healing following PRK. Purified amniotic fluid (pAF) contains anti-inflammatory, anti-microbial and regenerative factors similar to solid amniotic membrane. Individual patients will be randomized to one of two post-operative drop regimens, control eyes that will receive placebo saline solution (NaCl 0.9%, Baxter Medical), and study eyes that will receive pAF four times daily for seven days.

This is a randomized, double-masked, placebo-controlled study to determine

* the safety of pAF in patients who undergo PRK
* if pAF hastens re-epithelialization following PRK compared to placebo
* if pAF reduces post-operative pain following PRK compared to placebo
* if pAF affects visual outcome following PRK compared to placebo
* if pAF affects ocular surface staining and corneal regularity following PRK compared to placebo
