Swiss Leonardo da Vinci femtosecond laser is developed on the basis of Intraase. Compared with Intraase, whose laser emission frequency is only a few tens of KHZ, 1000KHZ Da Vinci femtosecond laser has many unique and perfect advanced technologies. Now, briefly describe some technical advantages over Intraase.
1, the patient's comfort of Leonardo da Vinci's femtosecond device is obvious: the doctor's operating handle of Leonardo da Vinci's femtosecond device is small and convenient to operate, and the freedom of spatial movement reaches 6 directions. The smaller handle reduces the threat to patients, which is beneficial to the cooperation of patients and has good comfort. IntraLase FS60' s doctor's operating handle is heavy, and the laser head can only move in XYZ three axes. During the operation, the patient's head must be strictly fixed for a long time, so the patient will feel very tired.
2. The thickness and shape of Leonardo da Vinci's femtosecond corneal flap are more ideal: the error of Leonardo da Vinci's femtosecond is less than plus or minus 6%, and the thickness of corneal flap is even and smooth, which obviously improves the postoperative repair speed and visual quality. The error of intrinsic ase fs60 is less than10%, and the edge is inclined.
3. How much laser energy does Leonardo da Vinci need to make corneal flap in femtosecond? Compared with endogenous ase, it has the least influence on surrounding tissues and the largest energy. Objective To maintain the structure of healthy cornea.
4. The operation time of Leonardo da Vinci's femtosecond is shorter: the light spot of Leonardo da Vinci's femtosecond is small and the energy is low, which minimizes the bubbles generated on the cutting surface, and the bubbles disappear immediately after the flap is lifted, so the patient can perform laser treatment without waiting. It is necessary to change the operating table or go to another room for excimer laser, and the operation time is obviously shortened. Because of the low frequency of laser emission, intrinsic ase femtosecond needs too much energy to adjust. After valve implantation, patients have to wait for the bubbles to disappear, and they need to change the operating table or even the operating room for subsequent excimer surgery, which greatly increases the uncertain factors that may affect the surgical effect and is not conducive to the cooperation of patients during the operation.
5. The operation of Leonardo da Vinci femtosecond device is simple, and the corneal flap can be easily lifted without any tissue connection, and the visual effect is better after operation. Intraplate FS60 interosseous connection is very common. Opening corneal flap often requires tweezers, sharp tools and mechanical force, which is easy to cause unpredictable adverse effects on postoperative visual effects.
6. When Leonardo da Vinci made the corneal flap in femtosecond, the laser head position was flexible and the corneal flap capacity was good. Therefore, what are the possible complications than IntraLase? Less.
Swiss Leonardo da Vinci femtosecond laser further expands the advantages of femtosecond laser. By making up for the defects of Intralase femtosecond laser and developing new technology, Leonardo da Vinci femtosecond laser has brought a new trend of all-laser bladeless era. From Intralase to Da Vinci, femtosecond laser has developed to a new height in the world.
