There's LASIK and LASEK as a way to correct your eyesight.

How are they different?

LASIK is, as you know, the most widely known surgical method of vision correction.
Proceed in the following order:
1. Cut the top of the cornea horizontally with a knife or laser to make a lid (corneal fragment).
2. Open the lid and peel the corneal substance underneath with a laser.
3. Cover the lid.
LASEK proceeds in the following order:
1. Peel off corneal epithelium with alcohol or a brush. Corneal epithelium grows back a few days after surgery.
2. Peel the cornea with a laser.
3. Cover the temporary protective contact lenses. It also covers hard lenses and takes them off when the corneal epithelium grows again.

LASEK hurts more than LASEK.
To compare it to a pain, toothache hurts to the point of going away.
There is painless lasek, but it is not 100% painless.

The stability of vision correction has not yet been verified.
Consider that Dr. Lee Tae-won, chairman of the LASIK and LASEK deliberation committee of the Korean Ophthalmology Association, is also wearing glasses.

LASEK's vision recovery is slower than LASIK's.
It usually takes three to four weeks and several months for vision to recover.

LASIK recovers faster than LASEK surgery, but it usually takes about two to three days to recover.
The price is also cheaper than LASEK.

The advantages of LASIK are as follows.
1. It is less painful than LASEK surgery because it cuts the deep part of the cornea.
2. Recovery is faster than LASEK surgery. You can recover in two to three days.
3. It's cheaper than other eye correction techniques.
The advantages of LASEK are as follows.
1. Because corneal fragments are not made, corneal fragments do not break off. Therefore, it is safe for strenuous exercise.
2. Less dry eyes.
3. The required corneal thickness is thinner than LASIK. The remaining cornea is thicker, making it less likely to develop conical cornea.
4. Treatment is possible even if the eyes are small.

The disadvantages of LASIK are as follows.
1. Corneal fragments may be pushed due to intense exercise. You should go to the ophthalmologist and cover it back in place with pain as if you put sand in your eyes.
2. The sensory nerves distributed in the cornea are not reconnected or recovered after being cut in the process of making corneal segments, so dry eyes are likely to become severe.
3. Both the thickness corresponding to the corneal fragment and the thickness to be peeled with a laser are required, so surgery cannot be performed if the corneal thickness is thin.
4. There is a limit to the calibration vision.
5. If your eyes are small, surgery is impossible.
The disadvantages of LASEK are as follows.
1. The pain is very severe because the treatment is performed on the corneal epithelium where the pain cells are concentrated. This is related to temperature, and a painless lasek has been developed to cool the treatment in between. However, no pain does not mean that it is 100% painless, and the degree of pain varies greatly from person to person.
2. Compared to other vision correction procedures, vision recovery is very late. Usually, it takes three to four weeks and months for vision to recover. Therefore, it is inconvenient to wear glasses or sunglasses for a long time after the procedure.
3. If there is a large amount of cutting, corneal opacity may occur during the recovery process. The corneal epithelium is a part that recovers by cell proliferation, which is generally fortunate when it is regenerated, but when the cut area is not generally regenerated and abnormally regenerated, it leads to corneal opacity and is blind. Normal regeneration is not at the discretion of the doctor, but the self-sustaining power of the cell, so the surgeon cannot expect it. If corneal opacity occurs, there is no other way to recover than corneal transplantation. However, corneal opacity can be treated by injecting drugs at the beginning of the outbreak. To prevent this, M-Lasek, which uses mitomycin (a type of anticancer drug used for cancer), has been developed to suppress cell proliferation during surgery.
4. In the case of astigmatism, the recovery period takes longer. In addition, correction is difficult unless you have early astigmatism.
