As people’s living standards improve, their demand for visual quality is getting higher and higher. Cataract patients are no longer satisfied with the basic vision restoration of “seeing” after surgery, but also demand “seeing”. The Femtosecond laser automates the three most critical steps of the traditional ultrasound surgery: blade incision, capsule tearing, and nucleus splitting, eliminating the need for a knife in the incision, reducing surgical trauma, and allowing for faster recovery.
It has four major advantages: 1. Minimally invasive: With the continuous innovation of surgical equipment for cataract treatment, the incision of cataract surgery has evolved to 3.2mm, 2.6mm, 2.2mm. However, if the incision is even smaller and has to be operated manually, the accuracy of the incision will be more or less inaccurate due to the experience of the surgeon, emotion, environment, quality of surgical instruments, and even repeated use of instruments, thus affect the final result. The femtosecond laser does not require a knife to make the incision, which completely gets rid of the possible damage to the eyes of people and instruments, and the whole process is completely controlled by the computer digitized femtosecond laser to complete, which is accurate and minimizes the standard deviation of the doctor’s operation.
2, “no” damage: Femtosecond laser instantly splits the cloudy lens (i.e. cataract) by laser, the whole process is monitored in real time by OCT images of the anterior segment, and the process of splitting the cloudy lens can be completed accurately according to the preoperative design with almost no damage to the eye, which reduces the surgical trauma and results in faster recovery after surgery.
In the past, cataracts reached the level of blindness, commonly known as “long ripening” before surgery. The use of femtosecond laser has brought the safety and success rate of surgery to a new level. Patients can choose surgery whenever they feel that their vision is unclear and affects their quality of life. This avoids the long and painful process from blurred vision to blindness of the patient and the possibility of complications such as glaucoma and uveitis caused by overripe cataracts.
4. Perfection of visual quality: In the past, cataract patients’ requirements for post-operative vision were only limited to the improvement of visual acuity. Now, with the improvement of people’s living standard, the requirements for post-operative vision are also gradually improved. Recently, the introduction of several new types of IOLs has brought a boon to cataract patients, but these high-end multifunctional IOLs require every step of the entire operation to be accurate. The error brought by human operation limits the effect of these high-end multifunctional crystalline lenses to a certain extent, while the femtosecond laser cataract treatment system is digitally controlled by computer and can achieve zero error, providing a guarantee for patients who need to obtain more perfect visual quality.
