Femtosecond laser for myopia The Intralase femtosecond laser is a true “full laser” with a 90 degree right angle laser during the flap making process, the flap is tightly embedded and occluded, the degree of occlusion is very tight, the post-operative vision recovery is very fast and good, guaranteeing the safety of the surgery, and the flap diameter and thickness personalization The setting improves the post-operative visual acuity and becomes the highest recognized femtosecond laser in the world. Jingzhou Central Hospital Ophthalmology Wei Fen Intralase femtosecond laser is currently the international brand with the first share of femtosecond devices, which was applied to clinical practice in 2001. It is now certified by the US FDA. The Intralase femtosecond laser is the most mature laser technology used by the most physicians in the world. How Femtosecond Laser Technology works: Before surgery, the surgeon enters the patient’s basic information and surgical data into a computer. During surgery, the surgeon operates the “femtosecond laser” machine, using a flattening cone lens to flatten the cornea and maintain a precise distance between the laser focus points in the corneal tissue of the laser head. The femtosecond laser delivers laser pulses in a pattern set by the surgeon to make various targeted cuts in the cornea. It can be said that the femtosecond laser has quite precise targeting and positioning. The advantages of femtosecond laser technology: 1. Significantly reduce the risk of surgery In traditional laminar knife surgery, if the blade rotation process occurs during the negative pressure ring loosening and other accidents, the production of the corneal flap will completely fail, the surgery can only wait for three months to do again, bringing great psychological pressure to patients and doctors. In the case of similar accidents with the femtosecond laser, the doctor will only need to put the negative pressure ring on again and immediately replenish the laser without interrupting the surgery. 2, more accurate reset The laminar knife is a horizontal cutting, and the surface of the eye is a sphere, so the flap profile is “cup” type, and the stroma of the eye is not good enough; while the femtosecond laser flap and the stroma of the eye is “underground well cover” type The flap is embedded in the eye, so it is easy to reset and bite tightly without misalignment, and there are no complications such as flap fragmentation or button flap. At the same time, its laser light source also avoids the residual metal debris that may be caused by the use of lamellar knife. 3, to avoid the medical source of infection in the use of lamellar knife in the production of corneal flap, some small medical institutions failed to strictly follow the “one person, one blade” principle, the disposable blade repeatedly used, which is easy to cause cross-infection. The “femtosecond laser” makes human beings leave the lamellar knife for the first time in corneal surgery, avoiding the occurrence of cross-infection and other situations. Femtosecond laser is more than 100 times more accurate than laminar knife, which is unmatched by laminar knife, and is safer for any patient. 5, not affected by corneal curvature In the past, the corneal thickness was affected by nearly 10% of the patients because myopia is too deep, the cornea is too thin, basically can not accept the traditional LASIK and other laser surgery. Femtosecond laser surgery is not affected by corneal curvature, which is a boon to myopic patients with thin corneas and large corneal curvature variants.
