PRK Laser Eye Surgery

PRK (Photo-Reactive Keratectomy) is our third-most-common laser technique which involves removing surface layers of the cornea before reshaping the stroma. Because it’s slightly more invasive, it can have a longer recovery time – and it’s not as common as less-invasive forms of laser treatment.  

PRK, also called Surface Laser Ablation, is a laser procedure using only an excimer laser to reshape the cornea. Unlike LASIK where a flap is created, in PRK the surface cells are first gently removed, exposing the layer underneath which is then re-shaped. The surface cells then regenerate but because this takes time the recovery is slower. Due to some discomfort and the longer healing period, PRK is used less now than when first introduced. It is still a proven and effective technique for correcting vision and a valid option for people with very thin corneas who are not eligible for our SMILE or LASIK options.

PRK is a good treatment to consider if you have:

  • Low to Moderate Myopia

  • A thin cornea

  • Low astigmatism

  • Previous laser eye/refractive surgery

Recovery

Because surface-level cells are removed and need to regenerate, recovery from PRK can take a few days. Following treatment, you will need someone to drive you home. You will probably be able to return to work and normal activities within five days, but it may take weeks to notice a change in your vision.
