Similar to LASIK procedures, PRK corrects vision by reshaping the cornea using an Excimer laser, which focuses light onto the retina to sculpt the stromal layer of the cornea and correct refractions. The primary difference between PRK and LASIK is that there is no flap created to access the cornea – the entire outer epithelial layer is removed to expose the area to the laser.

Although recovery for this process takes longer than usual, the lack of a requirement to cut and create a flap has led convinced several patients that PRK vision correction is often the safest option. Additionally, due to differences in the structure of the eye, some patients are better suited for a PRK procedure, particularly those who have thin corneas, high prescriptions, or topographic abnormalities.

Immediately after the PRK procedure, patients should plan a rest period of 3-4 hours with the eyes completely closed. There can be some minor sensitivity encountered after the surgery, but this discomfort is often mild and lasts for a short period of time. With proper care, regular administration of prescribed eye drops, and routine follow-up appointments, patients can recover smoothly and enjoy sharp and clear vision in a relatively short amount of time.
