PRK (Photorefractive Keratectomy) is often misunderstood. Many believe it’s outdated, painful, or less effective than LASIK. But is that true? Let’s separate PRK myths vs facts and uncover what PRK really offers.
If you’ve been considering vision correction surgery, you might have come across PRK. While LASIK is more commonly discussed, PRK is a tried-and-true procedure that has helped countless people achieve better vision. Unfortunately, misinformation about PRK is widespread, leading many to dismiss it prematurely. In this article, we will explore some of the most common myths about PRK and compare them to the facts.
What Is PRK?
PRK is a type of laser eye surgery designed to correct vision issues like nearsightedness, farsightedness, and astigmatism. Unlike LASIK, PRK does not involve creating a corneal flap. Instead, the outer layer of the cornea (epithelium) is removed to allow for laser reshaping. This makes PRK a preferred option for individuals with thin corneas or those at higher risk of flap complications.
Common PRK Myths vs Facts
| Myth | Fact |
| PRK is outdated compared to LASIK. | PRK is still widely used and recommended for certain patients, particularly those with thin corneas or active lifestyles. |
| PRK is extremely painful. | While discomfort is common in the first few days, proper medication and care help manage it effectively. |
| PRK has a longer recovery time than LASIK. | While PRK takes longer to heal, the final vision outcome is often just as good as LASIK. |
| PRK results don’t last as long. | PRK provides permanent vision correction, similar to LASIK. |
| PRK isn’t as safe as LASIK. | PRK eliminates the risk of flap complications, making it a safer choice for some patients. |
Additional Misconceptions
- PRK is only for people who can’t get LASIK. While PRK is often recommended for those with thinner corneas, some patients choose it because of its long-term stability and safety.
- Vision takes months to improve. Most patients notice significant improvement within the first few weeks, though full recovery may take a few months.
