Will the corneal flap heal more tightly than the traditional one by choosing femtosecond laser? Can you do strenuous exercise after half a year? Can you withstand a normal collision?

First of all, whether eye surgery is performed or not, the eye, as an organ that is not particularly strong, should not be collided. As a patient with high myopia, it is not recommended to carry out very strenuous exercise regardless of surgery. Femtosecond laser is not closer to corneal healing than traditional myopia surgery, but it makes the corneal flap and eyeball matrix bite in the form of "underground manhole cover", which is easy to reset and the bite is tight and not in position. Generally speaking, femtosecond laser, as the most advanced laser myopia surgery, has the advantages of better postoperative visual quality and wider correction range, especially the femtosecond laser with very high frequency by Leonardo da Vinci of Switzerland, which has very high accuracy in flap making.
