Semi-femtosecond, full femtosecond, PRK surgery and lcl crystal implantation surgery are introduced as follows:
1, using femtosecond laser device can complete all femtosecond surgery. All-femtosecond laser is to separate a lens from corneal stroma by femtosecond laser, and then make a 2mm incision on the cornea with laser to take out the cut lens. Suitable for myopia below 1000 degrees and astigmatism below 500 degrees.
2. Semi-femtosecond femtosecond laser only completes the manufacture of corneal flap, and excimer laser equipment is also needed to "cut" corneal tissue into "glasses". Suitable for myopia below 1200 degrees, astigmatism below 600 degrees and hyperopia below 600 degrees.
3. ICL lens implantation is to place an intraocular lens in front of the lens to correct vision, which is similar to implanting contact lenses in the eyes. The operation is safe and reversible. There are basically no crystals in the eyeball after operation.
4.PRK surgery is laser optical keratectomy. After the epithelium on the corneal surface is removed, the desired corneal tissue is vaporized by laser. The surgical equipment and operation are relatively simple, and the postoperative complications are relatively few.
