First of all, it is important to understand that any kind of surgery can't guarantee 100% completeness, but full femtosecond, as a kind of mature eye surgery, is still relatively safe. However, it is also important to note that having the surgery does not mean that you will never be nearsighted again in your life, and if you don't pay attention to your eye hygiene, you may still suffer from nearsightedness again.
Full femtosecond laser eye surgery is a tiny incision lens removal procedure. Full femtosecond laser myopia surgery is the use of femtosecond laser can be in the ultra-microscopic space precision focusing characteristics, according to the patient's preoperative examination data, with a femtosecond laser to produce a corresponding thickness of the corneal stromal lens and a small corneal incision, and then through the small corneal incision will be made to remove the good corneal stromal lens, after the removal of the corneal stromal lens, the corneal refractive power has been accurately remodeled, so as to achieve the goal of correcting the The purpose is to correct myopia.
Just as the thickness of a person's skin varies, so does the thickness of each person's cornea. However, all corneal surgeries are performed within safe limits. For patients with thin corneas or abnormal corneal patterns, the surgeon will not recommend full femtosecond surgery during the pre-surgery exam.
At the end of the day, full femtosecond surgery is a physical, optical redesign of the cornea to change the refractive power of the cornea. The principle of the surgery is actually to cut away the portion of the refractive power from the cornea that produces the myopic state and ultimately create a correct refractive state. Therefore, exactly how many diopters and how much astigmatism will be cut. These basic values are critical.
In the evolution of eye surgery, the full femtosecond is a technological development from all previous corneal surgeries and is a more sophisticated form of myopic corneal surgery. The first patients who underwent corneal surgery have experienced more than two decades of time verification, and there are no reports of problems related to sequelae, to some extent, represents the newer technology of full femtosecond should be more safe and reliable.
If there is a need for rapid correction of myopia people can refer to this technology, but the best way to go to a regular hospital to consult a regular doctor's advice, pay attention to eye hygiene in the weekdays, proper rest.
