It is indeed true that the two are similar in some respects, but they vary widely.

The most important difference is the two surgeries are appropriate for patients in different categories.

What are the cuts used, the first is suitable for the eyes, needing only a little 'or a small correction, while the second is a repair. And another difference is how to manage the corneas. The first is intended for patients whose corneal tissue is thick. While the latter is thin.

Another difference is that the former is suitable for surgery in patients with corneal tissue is cut much more, while the second only slightly.

Yet another difference is the thickness of the corneal flap in which the cornea is located. In the previous surgery, stromal tissue treated, while the epithelial tissue is treated in the surgery later.
