What are the advantages of laser vision?

Laser surgery for myopia may cause dry eye, refractive regression, overcorrection or undercorrection.

1. Laser surgery for dry eye

may cut off the sensory plexus in the anterior stromal layer of the cornea, resulting in decreased corneal perception in the early postoperative period, which may lead to dry eye in the early postoperative period, but most people can recover with time.

2. Refractive

regression refers to the decline of refractive power over time after surgery, generally more than 6 months. Most patients can maintain good refractive state after laser surgery, but some patients may cause refractive regression due to their own reasons or improper use of the eye.

3.

The result of laser surgery for myopia correction may be higher or lower than one hundred degrees, that is, overcorrection or undercorrection.
