Nowadays, more and more people choose to correct myopia through myopia surgery.
As the "leader" of femtosecond laser myopia surgery, ReLEx has undoubtedly become one of the ideal surgeries for many patients.
Today, for the reLEx myopia surgery, the matters that patients should pay attention to are sorted out together from the before, during and after the operation.
The whole process uses only one ZEISS ReLEx device, which uses a femtosecond laser to penetrate the corneal epithelial layer, make a microlens inside the stromal layer, and then remove the lens through a 2-4 mm incision.
It is equivalent to "making a pair of lenses" on the cornea to achieve the purpose of correcting myopia.
ReLEx surgery is one of the most advanced types of refractive surgery in China, and it is also almost the most popular myopia surgery in China.
First of all, the following conditions need to be met before the full femtosecond surgery is suitable.
1. Be between 18 and 45 years old, and have a stable degree in the past two years. (Because the eyeballs of this group have matured and the myopia is stable, the surgical effect is more guaranteed.) )
2. Myopia within 1000 degrees and astigmatism within 500 degrees. (Because the higher the power, the more corneal tissue needs to be cut, and there is a risk of overcutting.) )
ReLEx myopia surgery often has a safe, convenient, and almost painless label, although the operation time is short, but it is a long story, and today we will introduce it in detail from the three processes of preoperative, intraoperative and postoperative.
Three processes before, during, and after the whole femtosecond operation!
1. Preoperative - more than 20 strict examinations
In order to be safe, myopia surgery has a series of requirements, including more than 20 data tests, including: corneal thickness, corneal diameter, uncorrected visual acuity, optimal corrected visual acuity, fundus photography, tear secretion, etc.
These tests are not only done to obtain the data needed for surgery, but also to check for the risk of lesions in the eye.
Of course, the preoperative examination is not done casually, and it is necessary to prepare the eyes in advance.
2. During the operation - there is almost no pain in the whole process
Step 1: Enter the operating room.
Enter the operating room, wash your eyes and disinfect them, and the doctor will put a few drops of anesthetic on your eyes. The patient then closes his or her eyes and waits patiently for the surgery.
Step 2: Prepare for surgery.
Lie on your back on the operating table and slowly move to the appropriate position according to the instructions of ** to prepare for surgery.
Step 3: The specific process of surgery.
ReLEx surgery is done one eye after another.
The femtosecond laser scans the deep and superficial layers of the corneal stromal layer, and after scanning, it makes a convex lens, which the doctor removes through a small incision.
3. Postoperative - punctual dropping of potions, waterproof and foreign bodies
Just after the surgery, you need to avoid light, close your eyes, and drop eye drops, and you can rest and observe for about 1 hour, and then you can leave the hospital with sunglasses in a cool way.
There may be photophobia, tearing, and foreign body sensation within 3 hours after surgery, and clear vision can be restored to the naked eye after 4 hours, but there may be a slight fog and glare, which does not affect normal life. (There are individual differences, so recovery time varies from person to person.)
For other post-operative precautions, please keep it as well:
1. Do not use tissues or towels to contact your eyes directly.
2. Don't worry about postoperative subconjunctival hemorrhage.
3. After surgery, it is necessary to take medication according to the doctor's instructions. Avoid eye trauma and prevent foreign bodies from entering the eye. When washing your face and hair, try not to splash water in your eyes. Do not apply eye makeup for 1 week after surgery.
4. Wear sunglasses after surgery.
5. After surgery, you still need to pay attention to eye hygiene and don't overly fatigue your eyes.
6.After surgery, it is advisable to eat a light diet and avoid spicy foods as much as possible.
The specific type of surgery depends on your own eye condition. When it comes to the choice of myopia surgery, what matters is the eye condition, followed by the eye needs and cost.
