PRK or LASIK? What’s the Difference?   

If you’re told you aren’t a good candidate for LASIK vision correction but your doctor recommends PRK, you may have qualms about moving forward with this often-unknown procedure. However, the truth is that PRK existed well before LASIK came along – and it’s still routinely used today to correct refractive errors. In fact, you can get the same overall vision results with LASIK and PRK.  

The main difference between PRK and LASIK is that there is no corneal incision needed in PRK. Instead of creating a corneal flap (the first step in LASIK), a thin layer on your cornea (the epithelium) is removed to provide access to the underlying corneal tissue. This surgical difference also creates slightly longer and more uncomfortable recovery times for PRK. Therefore, final vision results may take longer to achieve.  

Here’s an overview of the difference between PRK and LASIK:
