The difference between Zeiss Half Femtosecond and Full Femtosecond surgery is as follows:
1. Smaller spot of Zeiss Half Femtosecond surgery results in more stable vision after surgery. The smaller the spot, the more effective the cutting, and the less damage to the corneal tissue. The stromal surface of the cut cornea is smooth, which can effectively reduce the impact of tissue proliferation on corneal curvature due to the roughness of the stromal surface, and the postoperative vision is more stable. ZEISS semi-femtosecond contact eye lens is uniquely designed, the specifications are divided into three kinds of large, medium and small, suitable for different eyes, flattening for curved lens, more in line with the physiological state of the cornea, intraoperative comfort is better. Aerospace femtosecond flattening is conical flattening, there is only one specification, if the eye is small, it is more difficult to place.
2, full femtosecond surgery throughout the use of Zeiss femtosecond laser, in the corneal stroma between the layers of the two different depths of the cutting scan, in the corneal stroma to do a diameter of 6 mm or so the size of the lens piece, do not make a corneal flap, and then do a 2 mm above the cornea of a tiny incision, along with this incision, separation and removal of the femtosecond laser lens-like piece of corneal tissue to correct myopia, and the femtosecond laser to create a lens-like piece of corneal tissue, to correct myopia. There is no need to lift the corneal flap. Full femtosecond surgery retains the integrity of the cornea, reducing the damage to the corneal nerve fibers, postoperative dry eye symptoms; the surgery also retains the continuity of the anterior stroma across the cornea, postoperative corneal dilatation of the risk is low, the operation is not afraid of trauma, impact resistance, the next day you can live a normal life, sports are not restricted, especially for the operation of the long term to participate in high-intensity antagonistic training of military personnel, police officers and athletes, and other people.
