Which is better femtosecond or femtosecond, and which is the best, femtosecond or femtosecond?

The femtosecond laser is removed through the corneal interlaminar lens, with an incision of 2mm, which is minimally invasive and fast, the operation is more accurate and safer, and the biomechanical impact and damage to the cornea are smaller, reducing the incidence of many complications such as dry eye syndrome, corneal flap displacement and infection.

Banfei is a femtosecond laser corneal flap + excimer laser corneal ablation surgery, which requires a 20mm incision on the cornea to form a corneal flap, and then the corneal flap is lifted for laser ablation, and then the corneal flap can be covered.

You can go to a professional eye hospital for examination first to see if you meet the conditions for surgery, what kind of surgery method is suitable for you, and what is suitable for you is the best.

The ** of full femtosecond is about 16,000, and the ** of half femtosecond is about 12,000.

If you have higher requirements for postoperative eye use, it is recommended to choose ReLEx after surgery. Preh Summer ReLEx is 16,000 yuan, and the main knife is Director Zhou Jirong.

The first thing that can be determined is that both surgical methods can achieve a normal corrected vision. Which is better depends on the patient's own situation, and it is best to check and choose the most suitable surgical method.

Full femtosecond. ReLEx laser is one of the most advanced corneal refractive surgery modalities in the world. It brings the safety and accuracy of myopia correction to a new level.

Due to the high development cost and the technical bottleneck that is difficult to break through, only the "full femtosecond" laser system of Zeiss in Germany can be applied to the "full femtosecond" myopia correction hand jujube stuffiness.

The main technical core of the femtosecond laser is to accurately locate the laser in the corneal stroma, make the corneal stromal endolens and remove it, so as to change the refraction of the cornea, which has been used in clinical practice. In the past, most of the femtosecond lasers used in LASIK surgery can only make corneal flaps, and must be combined with excimers to achieve the best purpose.

Full femtosecond laser refers to the full application of femtosecond laser system in the first process, cutting a specific diameter and curvature of the interface at the relatively deep layer of the cornea, and then cutting a slightly larger diameter of the special bench orange curvature interface at the relatively shallow corneal layer after completion, the two interface periphery intersect, in the dissection it forms a convex lens-shaped corneal thin layer tissue, with a special tool to take out the made dissection tissue, which is equivalent to the application of the principle of excimer laser cutting.

The unique corneal surgery system can change various cutting parameters, with extremely high performance and greatly reduced corneal thickness error. Therefore, it can be used in high-risk patients who have not been able to undergo surgery in the past. Become safer.

The unique design of the contact lens is suitable for different eyes with different specifications and sizes, and it can also avoid the discomfort caused by the increase in intraocular pressure during the negative pressure suction process, and the intraoperative cooperation is better. The whole process of the operation is minimally invasive, ensuring the "incision-free" state after the operation.

In terms of the results of the surgery, the results of the two surgeries are the same, and basically the vision will reach the left and right the next day after the surgery. In terms of healing time after surgery, femtosecond is faster than femtosecond.

Instead of making a corneal flap, the corneal stromal lens is made and then removed through a tiny incision of 2-4mm. ReLEx laser can reduce the damage to corneal nerve fibers, reduce the impact on corneal biomechanics, and greatly reduce the incidence of dry eye syndrome and ground state modification, thereby improving the quality of vision.

You can go to Shanghai Purui Eye Hospital for examination to avoid infection: do not touch the environment that may cause infection, prevent dust and stolen objects from entering the eyes, do not splash water into the eyes when washing hair, bathing, and face during the week after surgery, and do not swim for three months. Keep your eyes clean and free of makeup for two weeks.

The rest depends on you.

Generally speaking, these two types of surgery have the following differences:

The incision of ReLEx surgery is small, the recovery of the orange is faster, the corneal nerve is preserved to the greatest extent, and it is less likely to cause discomfort such as dry eyes after surgery. Since there is no need to open the cornea, even those who exercise a lot do not have to worry about the displacement or detachment of the corneal flap due to postoperative mobility or eye trauma.

Half femtosecond surgery has a larger incision than full femtosecond surgery, but it has a wider correction range and is an important complement to full femtosecond surgery. Some patients with thin corneas, high heights, and high astigmatism are not candidates for femtosecond surgery, but they can undergo femtosecond surgery. In addition, the cost of femtosecond surgery is lower than that of femtosecond.

ReLEx laser surgery and femtosecond laser surgery are both more advanced refractive errors and myopia surgeries, and it is impossible to simply explain who is better. No matter what kind of surgery there are certain risks, it is necessary to choose the appropriate surgical plan according to the actual situation, such as both are suitable, and the clinical practice is currently more recommended for full femtosecond laser surgery.

The differences between the two are analyzed as follows:

1. ReLEx laser surgery: This method has less damage to the corneal flap and can achieve the purpose of correcting vision. The advantages are that the surgical risk is low, the accuracy is high, the surgical incision is small, and the operation duration is short, but it is relatively high, and the surgical adaptation population is more limited than the semi-femtosecond laser surgery, such as some people whose corneas are too thin, too high in power or not suitable for full femtosecond laser surgery cannot pass the operation**myopia;

2. Half-femtosecond laser surgery: The advantage of this surgical method is that it is relatively cheap. However, the risk of complications after surgery is higher than that of ReLEx laser surgery, and the risk of surgery is relatively high.

For some people whose corneas are too thin, too high in prescription, or who are not suitable for femtosecond laser surgery, semi-staring femtosecond laser surgery can also be an option**.

The selection of specific surgical methods requires a series of examinations in the hospital, combined with their own examination results and economic level to choose the most suitable plan.
