What is Full Femtosecond Laser Myopia Surgery Full Femtosecond laser surgery is different from the past Femtosecond laser surgery, it not only can make corneal flap with Femtosecond laser, but also can do refractive correction surgery directly to treat myopia farsightedness and astigmatism. It combines both femtosecond laser and excimer laser into one. It is more precise, safer and more predictable. What are the advantages of full femtosecond laser, femtosecond laser Painless, blade-free, safe and accurate, avoiding the risk of corneal flap complications caused by the traditional corneal knife. What is the difference between femtosecond laser and excimer laser, all-femtosecond laser Femtosecond laser is a very short duration infrared laser with blast cutting, which makes corneal flaps by cutting at different levels of corneal tissue under arbitrary control. It is used to replace the automated lamellar knife to create corneal flaps. The excimer laser is a UV-cooled laser that has the ability to precisely “ablate” corneal tissue and change the shape of the cornea, thereby changing the refractive index of the cornea and correcting myopia. Excimer laser surgery requires a laminate or femtosecond laser to create a corneal flap before refractive surgery is performed. The all-femtosecond laser can be used instead of the excimer laser to correct refractive error. The all-femtosecond laser creates a convex lens within the corneal stroma and then removes the thin corneal tissue lens, minimizing the damage to the physiological structure of the cornea. What is personalized refractive surgery treatment? The shape of the human eye is very different, so personalized refractive surgery treatment is to provide patients with a personalized “tailor-made” surgical treatment plan according to each patient’s different corneal surface shape, different refractive error, and different aberrations. For example, excimer treatment with Q-adjustment based on the asphericity of the patient’s cornea is particularly suitable for nighttime drivers, improving night vision and reducing the incidence of glare and halos. There are currently several modalities of personalized refractive surgery treatment Q-value guided personalized refractive surgery, corneal topography guided personalized refractive surgery, and wavefront optimized refractive surgery. How Refractive Surgery Treatment Works Changing the refractive index of the cornea with excimer laser and full femtosecond laser is equivalent to customizing a pair of glasses on the corneal surface, and the postoperative naked eye vision reaches the best corrected vision with glasses before treatment. The results of the treatment to date have been satisfactory both domestically and internationally. Femtosecond laser surgery, excimer laser surgery is safe Must choose a professional eye hospital for detailed preoperative screening, strict selection of surgical indications, coupled with cutting-edge medical equipment, excellent medical technology and rigorous service attitude, in order to minimize the risk of surgery, the surgery is safe and guaranteed. What are the possible complications after surgery? In rare cases, infection, corneal flap displacement, corneal flap folds, diffuse interlaminar keratitis, dry eye, refractive regression, overcorrection and undercorrection, cone cornea, etc. may occur and need to be treated and handled according to the condition. People who are suitable for laser treatment Age 18 years or older, stable refractive error (less than 50 degrees per year), refractive error less than 1200 degrees of myopia, less than 600 degrees of hyperopia and less than 600 degrees of astigmatism in the past 2 years. Those who have no eye or systemic diseases, have a desire to remove their lenses, and have been wearing contact lenses for more than 2 weeks can undergo pre-operative examination. Will my normal life be affected after the surgery? How many days will it take for me to recover? What do I need to pay attention to? You can go to work and school normally the day after the surgery and recover your distance vision. Myopia can be recovered in a short time, avoid watching computer and TV for a long time within a month, no face washing, bathing, swimming and avoiding eye contact with water within a week. If myopia develops after surgery, can I still have a second surgery? If the corneal thickness is sufficient, the relevant examinations are all qualified for another surgery, and the developed refractive error is stable for more than six months, you can have another surgery.
