PRK

PRK (Photorefractive Keratectomy) is a type of refractive eye surgery used to correct refractive errors like nearsightedness (myopia), and farsightedness (hyperopia), with or without astigmatism. It was the first type of laser refractive surgery developed and is still widely used today. Especially for patients who aren't good candidates for LASIK.

How PRK Works: 

• In PRK, the outer layer of the cornea (epithelium) is gently removed.
• A laser is then used to reshape the underlying corneal tissue to correct the refractive error.
• A Bandage contact lens is placed on the eye allowing for the epithelium to naturally regenerates over a few days after surgery. 

PRK is a great option for patients who:

• Have thin or irregular corneas (not suitable for LASIK)
• Have dry eyes or are at higher risk for flap complications
• Are in professions or sports where eye trauma is a concern (no flap = less risk) 

Recovery: 

• Initial healing: 3–5 days
• Vision clarity: Improves gradually over several weeks
• Eye drops and bandage contact lens: Used for healing and comfort

Risks/ Side effects: 

• Temporary haze, vision fluctuation, light sensitivity, glare/halos at night
• Longer visual recovery time than LASIK
• Rare but possible: infection, under- or over-correction
