Full femtosecond advantage:
Full femtosecond surgery does not need to cut the cornea to make a typical corneal flap, so the incision on the corneal surface after surgery is very small, there is no annular wound, and there will be no serious dry eye after surgery, which is suitable for patients with severe dry eye before surgery.
Full femtosecond disadvantages:
Not suitable for patients with thin corneal thickness and high degree. Patients with thin cornea and high myopia may be more prone to postoperative complications if they undergo full femtosecond surgery, resulting in worse postoperative results than half femtosecond surgery.
Semi-femtosecond advantage:
The visual acuity recovered quickly after semi-femtosecond surgery, and most patients' visual acuity may improve to 1.0 after 1-2 days. Semi-femtosecond surgery is more suitable for patients with higher degrees.
Semi-femtosecond disadvantages:
Semi-femtosecond surgery needs to remove a corneal flap, so it will leave a circular minimally invasive incision on the cornea, so the symptoms of dry eye will be more obvious after semi-femtosecond surgery.
Therefore, both surgical methods have their own advantages and disadvantages, and the choice of specific surgical methods needs to be targeted according to the design. Click to test whether I am suitable for myopia surgery.
