Are you tired of the daily hassles that come with wearing glasses or contact lenses? Have you been considering laser eye surgery but were told that your thin corneas might make the procedure risky? You’re not alone. This is a common concern for many people in your situation. But there’s good news – PRK (Photorefractive Keratectomy) could be the answer you’ve been searching for. This comprehensive guide is designed to help you understand is PRK and why it could be the perfect solution for those with thin cornea. So let’s get started!

What Causes Thin Corneas?

What Causes Thin CorneasWhile some individuals are born with naturally thin corneas, others might experience thinning over time due to various factors.

A common cause of thin corneas is keratoconus, a progressive eye disease that causes the cornea to thin and bulge into a cone-like shape. This condition distorts vision and can complicate corrective eye surgery.

Another cause can be improper contact lens usage. Wearing hard or poorly fitted contact lenses over a long period can stress the cornea, leading to thinning.

Eye injuries or surgeries can also result in thinner corneas. Certain surgical procedures, especially repeated ones, may remove or alter corneal tissues, leading to a thin cornea.

Last but not least, some systemic diseases like Ehlers-Danlos syndrome or osteogenesis imperfecta are associated with thin corneas. However, these cases are rare.

Is There A Treatment For Thin Cornea?

When it comes to treating thin corneas, it’s crucial to remember that thin corneas aren’t usually a problem unless they cause discomfort, interfere with vision, or complicate surgical procedures. As a result, the treatment strategy is heavily influenced by the root cause and the individual’s unique circumstances.

PRK offers an excellent alternative to traditional LASIK surgery for individuals with thin corneas. As mentioned earlier, PRK does not involve creating a flap in the cornea, thus preserving more corneal tissue. This means even those with thin corneas can safely undergo this procedure.

Why is PRK Suitable for Thin Corneas?

Benefits of PRK for Thin CorneaPRK is particularly suitable for those with thin corneas due to its unique process that distinguishes it from other forms of laser eye surgery, such as LASIK.

In LASIK, a thin flap is created on the cornea’s surface, and the laser treatment is applied to the tissue underneath. This means a certain amount of corneal tissue needs to be left untouched to maintain the cornea’s structural integrity. In cases of thin corneas, creating this flap and leaving sufficient untouched tissue can be challenging.

This is where PRK comes in. PRK does not involve the creation of a flap. Instead, the outer layer of the cornea (the epithelium) is gently removed, and the laser treatment is applied directly to the cornea’s surface. This approach conserves more corneal tissue, allowing PRK to be safely performed even on thin corneas.

In addition, not having of a flap reduces the risk of flap-related complications, which, while not common, can be difficult in LASIK procedures. This is another reason why PRK is often recommended for individuals with thin corneas.

Lastly, PRK has a long track record of successful outcomes, with many patients achieving 20/20 vision or better. So, while the recovery period might be slightly longer compared to LASIK, the potential for excellent long-term vision results makes PRK an attractive option for those with thin corneas.

Potential Risks of PRK for Thin Cornea

Despite its many benefits, it’s important to consider some potential risks and drawbacks associated with PRK:

  • Longer Recovery Period: The recovery period for PRK is usually longer compared to LASIK. This is because the cornea’s outer layer needs time to heal and regenerate after the surgery.
  • Temporary Discomfort: Some patients may experience discomfort or mild pain in the first few days following PRK. This is temporary and usually resolves as the eye heals.
  • Risk of Haze: There is a small risk of corneal haze with PRK, particularly for higher corrections. However, with the use of modern laser systems and preventative measures such as the use of mitomycin-C during surgery, this risk has been significantly minimized.

Remember, the suitability of PRK and the balance of its benefits and risks will vary depending on your individual circumstances.

Is PRK Better Than LASIK for Thin Cornea?

Is PRK Better Than LASIK for Thin CorneaIf you have thin corneas and are contemplating refractive surgery, you might find yourself asking: Is PRK a better choice than LASIK for me? The answer largely depends on your individual circumstances, but in many cases, PRK does hold an advantage for those with thin cornea.

To ensure the cornea retains its strength and stability after surgery, a certain thickness of corneal tissue must be preserved. This requirement can make LASIK less suitable, or even unsuitable, for those with thin corneas.

Secondly, the laser treatment is applied directly to the cornea’s surface, preserving more of the underlying corneal tissue. This feature makes PRK a more feasible option for individuals with thin corneas, even when a significant degree of refractive correction is needed.

Moreover, PRK eliminates the risk of flap-related complications, a concern in LASIK procedures. So, if you have thin corneas, PRK often proves to be a better choice than LASIK. However, it’s crucial to have a thorough consultation with an experienced eye surgeon to understand the best surgical option for your specific condition and vision correction needs.


In summary, PRK is a fantastic choice if you have thin corneas and are considering refractive eye surgery. By preserving more corneal tissue and eliminating flap-related complications, PRK often becomes a better alternative than LASIK for individuals with thin corneas.

But remember, an experienced eye surgeon should make the final call after a thorough consultation. They will consider your specific condition and vision correction requirements.
