What Are the Types of Laser Surgery for Myopia?
Disease description:
I’m about to start university and would like to get rid of my glasses—I’m considering surgery. Others have mentioned there are several options available; could you please explain the different types of laser vision correction procedures for myopia?

Laser vision correction procedures for myopia include excimer laser surgery, femtosecond-assisted LASIK (often called “semi-femtosecond” laser surgery), and small incision lenticule extraction (SMILE), also known as “all-femtosecond” laser surgery. Excimer laser surgery corrects myopia by reshaping the cornea’s curvature—specifically, by precisely ablating the anterior corneal surface to alter its refractive power. Semi-femtosecond laser surgery involves using a femtosecond laser to create a corneal flap; after lifting the flap, an excimer laser is applied to reshape the underlying corneal stroma. SMILE is a minimally invasive procedure offering rapid visual recovery postoperatively and is currently the most popular surgical option.
