PRK (photorefractive keratectomy) is a first-generation laser eye surgery that consists of using an excimer laser to treat any refractive eye condition.
Refractive eye surgery aims to correct ametropia with a medical device such as a laser or ocular implants (intraocular lenses).
This surgical procedure implies the removal of the corneal epithelium in order to reshape the corneal curvature and correct eye conditions.
Photorefractive keratectomy (PRK) is a laser technique that is used to treat low to mild myopia (-5D). This cost-effective method has been approved for decades now. However, there are several drawbacks to this technique: some post-surgery discomfort (sometimes even some pain) as well as a longer recovery time.
