Is LASEK Dangerous Because of Corneal Epithelium Removal?

How is the Corneal Epithelium Removed?



LASEK surgery involves removing the corneal epithelium. The most basic method is to use alcohol to loosen the corneal epithelium, making it easier to remove. Then, LASEK brush is used to gently rub and remove the epithelium. This process removes only the epithelium without causing abrasion on cornea.



LASEK brush has a design similar to an electric toothbrush. When the rotating brush is applied to the eye, it gently removes the epithelium.


Does LASEK brush necessary for surgery?



There is a type of LASEK surgery that can be performed entirely with laser. The official name for this procedure is All-Laser LASEK


With All-Laser LASEK, the surgery i


s performed solely by the laser without the need for manual instruments. 

Once the laser completes its process, the protective lens is applied to the eyes, and then the surgery is finished. 

All-Laser LASEK is not only simple but also fast and precise.


Is All-Laser LASEK the best option?



Using a LASEK brush or surgical solution to remove the epithelium ensure that only the necessary epithelium is removed, leaving 100% of the corneal storm intact. However, ALL-Laser LASEK is performed using average preset values for laser rather than being customized for each individuals. For this reason, it results in a slightly higher rate of corneal tissue loss.


Although I might seem that the cornea would be in pain, in fact, there is no pain. However, because the corneal epithelium has been removed during surgery, you may experience some discomfort in the eyes for 2 to 3 days.
