**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

 

| Feature | **PRK** | **LASIK** |
| --- | --- | --- |
| **Tissue Removal** | Surface only (no flap) | Creates a corneal flap |
| **Healing Time** | Longer (3–5 days of discomfort; full vision in weeks) | Faster (1–2 days) |
| **Post-Op Pain** | More discomfort during early healing | Minimal discomfort |
| **Risk of Flap Issues** | None (no flap created) | Flap-related risks (dislocation, wrinkles) |
| **Ideal For** | Thin corneas, active lifestyles | Thicker corneas, quick recovery needed |
