LASIK vs LASEK Which one is better
February 4, 2009
LASIK means Laser-Assisted in situ keratomileusis. A microkeraome is used to cut a small layer of cornea. A laser is then used in order to reshape the cornea that is behind that cut layer.
LASEK means laser epithelial keratomileusis. It is a combined form of PRK or photorefractive keratectomy and LASIK. Instead of cutting through the cornea, LASEK loosens the epithelium with the help of alcohol so that it disconnects from the stroma. Now you can simply roll it back.
The difference between the two techniques is that in LASIK, both the cornea and stroma are cut, whereas in LASEK, only the epithelial is cut.
If your cornea is not thick enough to undergo LASIK, then LASEK is for you. In addition, it takes less time to heal compared to LASIK.
Pros of the LASEK eye surgery
This surgery has many benefits of its own.
The process of first cutting a flap and then the job of attaching it back in the cornea is complicated. This complication can be totally avoided with LASEK.
LASIK causes eye dryness more frequently compared to LASEK.
Cons of LASEK eye surgery
There are two sides to every coin, so here are the disadvantages of this surgery.
It takes longer for LASEK surgery patients to obtain visual recovery. Usually, they have to wait for one or two weeks before they can fully gain functional vision when their eyes are recovering. However, LASIK surgery offers the advantage of vision recovery as fast as a day after surgery.
LASEK surgery involves more discomfort and even more pain than LASIK surgery. However, the breather is that it does not cause as much pain as PRK eye surgery does. The discomfort can linger for about two days.
LASIK requires you to wear no protective bandage post-surgery. However, LASEK requires the patients to have a bandage contact lens. They have to wear it for at least 3 days post surgery. This helps to protect the eye from the blinking of your eyelids.
If you have had LASEK eye surgery, you will be required to continue using topical steroid eye drops much longer than if you had LASIK surgery.
