The approximate cost of laser surgery for myopia

As of December 6, 2019,Laser surgery for myopia costs about $8,000 to $18,000, and the safety features are excellent.

Laser surgery for myopia includes Laser Optical Keratectomy (Photo Refractive Keratectomy, or PRK), and Excimer Laser In Situ Keratomileusis (Lasik, or IK).

There are six stages in the development of excimer laser subepithelial keratomileusis (LASEK), wavefront aberration-guided excimer laser surgery (Torsion Lasik (TK)), femtosecond, and full-femtosecond lasers.

Before the surgery, the doctor inputs the patient's basic information and surgical data into the computer (including the depth of laser focus, that is, the distance from the bottom of the cone lens to the laser focus point; the diameter of the corneal flap, the size and width of the tip; and the energy of the laser cutting, etc.). The surgeon operates the femtosecond laser machine during the procedure, holding the cornea in place with the conical lens, thus maintaining a precise distance from the laser head to the laser's focusing point in the corneal tissue.

The depth of laser focus, which is the distance from the bottom of the conical lens to the laser's focusing point, allows the femtosecond laser machine to deliver laser pulses in a pattern set by the surgeon to make various targeted cuts in the cornea. Briefly, what impresses us most about the femtosecond laser's light delivery principle is the precise directionality and exact positioning of the light delivery.

Surgical attention to the following:

1, the patient pre-operation You should clearly explain to the doctor the purpose and requirements of your surgery, and understand whether you are suitable for the surgery and the results you may achieve after the surgery.

2. Understand the general process of the surgery, and what may happen during and after the surgery.

3. Sign the consent form after you have decided to undergo surgery with full understanding of the risks involved.

4. You should generally stop wearing soft corneal contact lenses (contact lenses) for 1-2 weeks and hard corneal contact lenses for 3 weeks before surgery.

5, 3 days before the operation should generally be topical antibiotic eye drops.

6, preoperative gaze training should be done in order to cooperate well with the doctor during the operation.

7, myopia surgery should have enough sleep the night before.

8, wash your face on the day of surgery, do not wear make-up on your eyes, so as not to make it difficult to clean and disinfect your eyes before the surgery, and if you do not clean them thoroughly, you can make some fine particles enter the surgical area: do not use perfume and irritating-smelling cosmetics, so as not to interfere with the working state of the laser machine and affect the effect of the surgery.
