What about 500 degrees?

Thin lenses and light frames The preferred method of correcting myopia 500 degrees is to wear glasses. You can choose thinner lenses and lighter frames, which can reduce the overall weight of the glasses. Contact lenses can also be used. When the patient is over 18 years old, excimer laser surgery can also be performed to correct myopia. At this stage, the commonly used surgical methods are half-femtosecond laser, femtosecond laser, LASIK laser, etc. Among them, all-femtosecond laser is an excimer laser method with high safety at this stage. There is no need to make corneal flap during surgery, and there is no need to worry about corneal flap displacement after surgery.
