Is it possible to perform Smile LASIK for a reoperation?

About 20 years ago, I had LASIK because my eyesight was poor. Since then, I have been able to see the bright and clear world for over 20 years, which was very comfortable and good, but recently my vision has become blurry and I can't see objects clearly. The discomfort is indescribable. Can someone who had LASIK before also undergo the procedure again? What are the differences between the previous LASIK and the current Smile LASIK? I saw that Gangnam Brand Eye Clinic was recommended as a safe and well-performing hospital in Seoul. Is this place good? I have so many questions.ㅠㅜ
