First, use femtosecond laser to open the cornea, then use laser to "cut" the things inside the cornea into "glasses", and then cover the cornea back.
Advantages: rapid vision improvement.
The visual acuity can reach 1.0 immediately after operation, and the problems such as astigmatism can be solved at the same time.
Disadvantages: pain, dry eyes
The operation is slightly painful, afraid of pain, and older people should consider it more.
I will feel dry eyes after the operation, and it will take about half a year to recover slowly.
Because the cornea needs to be opened, there is a hidden danger of displacement, but it will hardly fall off, but boxers and astronauts still can't do this operation.
Surgery cost: The cost of binocular surgery is about 15000 yuan.
2. Full femtosecond surgery (smile)
This kind of surgery does not need to open the cornea, directly "cut" the "glasses" on the cornea with a laser, and then cut a small mouth to take out the "cut" things.
Advantages: the cornea is not prone to problems.
Because the cornea is not opened, only a small incision is made at the edge of the cornea, so the possibility of corneal problems is less and the postoperative recovery is faster. Anyone who likes sports and boxing can do it. In addition, the symptoms of dry eye after surgery are lighter than those of semi-femtosecond surgery, and people who are prone to dry eye can also do it.
Disadvantages: it is difficult to operate.
The disadvantage is that there is an incision. Although the incision is small, there is still an incision, which will leave corneal scars after surgery. In addition, due to technical difficulties and many surgical steps, complications such as corneal stroma lens tearing or tissue residue, lens removal difficulties may occur. Therefore, it is very important to choose a doctor with good skills.
Surgery cost: The cost of binocular surgery is about 20,000 yuan.
3. Trans-PRK surgery
Directly cut the surface layer of cornea into "glasses".
Advantages: safety
TPRK is a direct operation on the surface layer of cornea, and there is no incision, so naturally no scar will be left, and the operation effect is better. In addition, the operation is simple and can be completed in one step, but it is safer. Athletes, soldiers, policemen, firefighters and other occupations with a large amount of exercise are most suitable for this operation ~
Disadvantages: I feel a little uncomfortable, and I can't do it with high education.
After operation, the irritation symptoms such as tears, photophobia and foreign body sensation are slightly severe, lasting 1-2 days, with poor comfort, and it takes about a week for vision to return to normal.
For high myopia, the incidence of corneal opacity is high, and myopia above 700 degrees is not suitable for PRK surgery.
Surgery cost: the cost of binocular surgery is only about 10000 yuan, which is definitely the king of cost performance! If you are an athlete with low myopia and are not too afraid of pain, this operation must be the first choice!
Note:/kloc-myopia above 0/200 degrees is absolutely not allowed to do laser!
4.ICL crystal implantation surgery
ICL is to make glasses smaller and put them in your eyes.
Advantages: people with high myopia can do it and recover quickly, people with myopia below 2000 degrees can do it, and people whose cornea is too thin to do laser surgery can also consider trying ICL.
The postoperative recovery is rapid, and it will be fine in 3-5 days.
Disadvantages: it may be infected.
Because something is added to the eyes, there may be problems such as infection, cataract and glaucoma, but the probability is extremely small. Pay attention to your own care after general surgery. If you don't feel well, just call a doctor in time.
Surgery cost: The binocular surgery cost is about 30,000 yuan.
Although myopia surgery has certain risks, it is still very safe with the current medical technology. Remind you to find a regular eye hospital and a professional eye doctor to minimize the risk of surgery and make your world clear.
