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.

PRK can also be used to treat astigmatism.

Photorefractive keratectomy (PRK)

 Eligibility to a laser eye surgery treatment:

  • Have a stable refractive error for at least a year before the surgery
  • Cornea should be thick enough (determined by the pre-operative examination)
  • Be at least 18 years ago

When is a refractive laser eye surgery is contraindicated?

  • Cataract
  • Advanced glaucoma
  • Corneal condition
  • Pregnancy or breastfeeding
  • If your cornea is thin or your eye disorder is too serious, a laser eye surgery won’t be enough. You may be redirected to another type of treatment: Lens replacement surgery, for example. This method aims to replace your crystalline lens with an artificial intraocular lens or to implant a second lens (phakic IOL (+63 D)).
