Why LASIK May Not Be Ideal for Contact Lens Wearers and Why TransPRK is a Better Option
For contact lens wearers considering permanent vision correction, LASIK might not be the best choice. While LASIK is a popular procedure, it has certain drawbacks that can be especially problematic for those who have relied on contact lenses. TransPRK (Transepithelial Photorefractive Keratectomy) offers a compelling alternative, addressing many of these concerns. Here’s why TransPRK might be a better option for contact lens wearers.
Drawbacks of LASIK for Contact Lens Wearers
Corneal Thickness Requirements
Contact lens wear can sometimes lead to changes in corneal thickness and shape, potentially disqualifying some patients from LASIK. LASIK involves creating a flap in the cornea, which requires a certain corneal thickness to be safe and effective. If the cornea is too thin or irregular due to prolonged contact lens use, LASIK might not be advisable.
Dry Eye Syndrome
Extended contact lens wear is a known risk factor for developing dry eye syndrome. LASIK surgery, which involves creating a corneal flap, can exacerbate dry eye symptoms. The procedure can disrupt the corneal nerves responsible for tear production, leading to increased dryness and discomfort post-surgery. For contact lens wearers already experiencing dry eyes, this can be particularly problematic.
Flap Complications
The creation of a corneal flap in LASIK surgery introduces the risk of flap-related complications, such as flap dislocation or wrinkling. For individuals who have worn contact lenses for many years, the corneal surface might already be compromised, increasing the likelihood of these issues.
Advantages of TransPRK for Contact Lens Wearers
TransPRK, a surface-based laser vision correction technique, avoids many of the issues associated with LASIK. Here’s why it’s often a better choice for contact lens wearers:
No Flap, No Complications
TransPRK does not involve the creation of a corneal flap. Instead, it removes the outermost layer of the cornea (the epithelium) before reshaping the underlying tissue. This eliminates the risk of flap-related complications entirely, making it a safer option for those with compromised corneal surfaces due to long-term contact lens wear.
Preservation of Corneal Thickness
Since TransPRK is a surface procedure, it preserves more of the corneal tissue compared to LASIK. This is particularly beneficial for contact lens wearers who may have thinner corneas. The preservation of corneal thickness can lead to more stable and safer outcomes.
Reduced Dry Eye Risk
TransPRK has a lower incidence of dry eye syndrome compared to LASIK. Because it is a surface procedure and does not disrupt the deeper corneal nerves, the risk of exacerbating dry eye symptoms is minimized. For contact lens wearers already prone to dry eyes, this can result in a more comfortable post-operative experience.
Better Suitability for Irregular Corneas
Contact lens wear can sometimes cause changes in the cornea’s shape, leading to irregularities. TransPRK can be a better option for these cases because it does not rely on creating a uniform flap. The advanced laser technology used in TransPRK allows for precise reshaping of the cornea, addressing irregularities more effectively.
Faster Visual Recovery for Some
While the initial recovery from TransPRK may involve more discomfort than LASIK, some patients experience faster and more stable visual recovery over time. This can be especially beneficial for contact lens wearers who may have had fluctuating vision due to lens wear and irregular corneal surfaces.
