Post Photorefractive Keratectomy (PRK) Use of an Eye Shield for Maintaining Vision and Mitigating Pain (Nexis-CS0032)
The purpose of this research is to determine if an investigational thin shield over the cornea can safely and effectively reduce or eliminate pain following Post Photorefractive Keratectomy (PRK).
The thin shield is made of silicone. The materials used to make the corneal shield all have a history of use in medical devices, contact lenses, and/or corneal shields and have been used safely in the eye.
