Compared with traditional surgery using frontal muscle strength, CFS has the following advantages:

Advantages of CFS as a repair organization

1. Mechanical properties of levator palpebrae superioris muscle closest to normal open eyes;

2. Without changing the innervation when opening eyes, it is most conducive to the coordinated opening movement of eyes and the coordinated movement of eyelids and eyeballs.

3. when 3. CFS is suspended, it is not a traumatic tissue flap that is cut and separated, but a basically independent and complete structure, which will not adhere to the orbicularis oculi muscle and skin, and will not hinder the eye-closing function of the orbicularis oculi muscle.

4. It is composed of collagen fiber, elastic fiber and smooth muscle fiber, and its elastic fiber content is close to levator palpebrae superioris and rectus superioris.

5. Your own organization will not exclude others.

6. Basically, it is used in situ, with no trauma and no absorption, fibrosis or degeneration.
