Abstract: in order to reduce the operation cost, many small laser ophthalmic institutions do not strictly implement the principle of “one person, one blade” and reuse the disposable surgical blade, which greatly increases the medical hidden dangers such as cross infection. “Femtosecond laser” makes human leave the lamellar knife in corneal surgery for the first time, so as to avoid cross infection during the operation.
femtosecond laser myopia surgery is a common and mainstream surgical method to correct myopia. More and more myopia patients accept and choose femtosecond laser for vision correction! It has incomparable advantages –
1. It is safer without knife and greatly reduces the operation risk. When making corneal flap, the
femtosecond laser only produces some water and bubbles to push away the corneal tissue without damage to the tissue. It can perform multiple operations on the same affected area, and the safety is greatly improved.
2. Avoid iatrogenic infection
when many small laser ophthalmic institutions implement LASIK surgery, in order to reduce the operation cost, they do not strictly implement the principle of “one person, one blade”, and reuse the disposable surgical blade, which greatly increases the medical hidden dangers such as cross infection, “Femtosecond laser” makes human beings leave the lamellar knife in corneal surgery for the first time, so as to avoid cross infection during the operation.
3. The embedded corneal flap is more accurate. The
lamellar knife cuts horizontally, and the eyeball surface is a sphere, so the profile of the corneal flap is “cup cover” type, and the fixation with the eyeball matrix is not good enough; The corneal flap made by femtosecond laser is embedded with the eyeball matrix in the form of “underground well cover”, which can be easily reset and tightly occluded without dislocation, and there will be no complications such as broken flap and button flap.
4. The postoperative visual quality is more perfect.
“femtosecond laser” can accurately open the molecular chain of eye tissue and produce a more uniform and perfect corneal flap, avoiding glare and blur under visual conditions such as fog, rain and driving at night, so that myopia can obtain perfect visual quality.
5. The accuracy of
“all laser” surgery is increased by a hundred times. The accuracy of “femtosecond laser” is more than 100 times that of lamellar knife, which is beyond the reach of lamellar knife and is a safer choice for any patient.
6. The scope of correction is wider.
in the past, affected by technology, nearly 10% of patients were unable to accept traditional LASIK and other laser operations due to thin cornea and other reasons. Femtosecond laser surgery is not affected by corneal curvature, which is a great blessing for myopia patients with thin cornea and large variation of corneal curvature. The central thickness of cornea of
people is about 0.5mm. Surgery on such a transparent, delicate and thin cornea has high requirements for doctors’ psychological quality, professional ability, surgical experience and surgical equipment.
