In our daily lives, we often receive LASIK or LASEK surgery if we are suffering from some very common eye problems, as nearsightedness, farsightedness, astigmatism, etc.
But most of us can not tell whether there is any difference between the two.
In fact, they are of totally different categories, though the same laser and time are employed in the surgery.
In fact, it is true that the two are similar in some ways, but they vary very much.
Let's take a look at the names of the two abbreviated names-LASIK is abbreviated from Laser-Assisted in Situ Keratomileusis and LASEK from Laser Assisted Sub-Epithelial Keratomileusis.
The foremost difference is the two surgeries are suitable for patients of different categories.
As for how the surgeries are operated, the former is suitable for eyes that are in need of little or minor correction, whereas the latter is for great correction.
And another difference between the two is how to deal with the corneas.
The former is for patients whose corneal tissues are thick.
While the latter is thin.
Another difference is that the former surgery is suitable for patients whose corneal tissues are to be cut a lot, while the latter only a little.
Still, another difference is the thickness of corneal tissue flap, under which corneas are located.
In the former surgery, the stroma tissue is treated, while the epithelial tissue is treated in the later surgery.
Some investigations have revealed that LASIK surgery can make patients felt much better than LASEK, less pain and less discomfort.
On the contrary, the LASEK surgery will lead to no complications in stromal flaps.
If you are not sure about the two surgeries and you do not know which one fits you most, you can visit your eye doctors and consult some related matters with them.
They can provide you the best solution for your eyes.
