A comprehensive understanding of femtosecond surgery and Zeiss VisuMax equipment from Germany

Introduction: When it comes to myopia surgery, many people's first reaction is full femtosecond. They often ask, "Doctor, what equipment do I use for full femtosecond surgery?" "What brand and model is the surgical equipment?" These questions may seem simple on the surface, but they reflect the high concern of people for surgical safety and effectiveness. Today, we will take you to learn more about full femtosecond surgery and official certification of the German Zeiss VisuMax equipment. The founder of the German Zeiss VisuMax full femtosecond laser. The world-renowned optical instrument equipment manufacturer - Carl Zeiss of Germany - has launched a global full femtosecond laser refractive surgery system called "VisuMax", leading corneal refractive surgery into the era of full femtosecond laser surgery, which is an important milestone for full femtosecond laser surgery

This device adopts high-frequency and low-energy femtosecond laser technology, with a laser pulse frequency of up to 500kHz and a single pulse energy of about 170nJ. Only the "VisuMax" surgical system has bid farewell to the combination with excimer laser for the first time. By using the principle of femtosecond laser light blasting, different thicknesses of lenses are cut in the matrix layer to complete surgical correction of different refractive states, truly realizing the concept of "no knife" and "no flap" corneal refractive surgery

Due to its more precise cutting, more stable postoperative corneal biomechanics, less refractive regression, less postoperative dry eye, and better postoperative visual quality, this surgery has become the preferred choice for more and more people, especially for young people who love outdoor sports, have confrontational sports needs, and work nature such as conscripts, police officers, athletes, etc

Can the visual acuity recover to 1.0 after full femtosecond surgery? Answer: Actually, it's not. It also depends on the individual's recovery situation. Some people are less than 1.0, while others can recover to 1.2/1.5. This is closely related to an individual's corneal thickness, degree of myopia, and postoperative care. Regardless of the specific postoperative visual acuity, removing glasses generally results in better visual acuity than wearing glasses. What conditions are required for full femtosecond surgery to be suitable? Answer: Age between 18-45 years old; Myopia degree is less than 1000 degrees, astigmatism is within 500 degrees, and the degree has been stable in the past two years (although experience shows that there are very few people who can do full femtosecond when the degree is above 800 degrees); The corneal thickness should be sufficient, and the remaining corneal thickness after surgery should be within a safe range; Appropriate pupil size (people with pupils larger than 7mm are prone to glare after surgery); • There is no acute keratitis, corneal ulcer and other diseases in the eye, nor systemic problems such as diabetes and immune diseases. (Special reminder: It is recommended to choose the surgical method for myopia surgery based on the individual's preoperative comprehensive examination report and the doctor's professional customized plan.) 03 Why does full femtosecond surgery require higher corneal thickness? Answer: Half femtosecond requires lifting the flap, but saves the cornea; Full femtosecond does not require flap preparation and consumes more of the cornea than half femtosecond, but preserves the integrity of the cornea. What are the reasons why more people choose Aier Eye Hospital for myopia surgery? Answer: Firstly, Aier Group is a listed medical brand with a global layout of over 900 ophthalmic institutions; The second is the full femtosecond authentication device, Zeiss VisuMax from Germany; Thirdly, the Refractive Surgery Department of Humen Aier Eye Hospital is led by a team of master's and doctoral experts, providing one-on-one personalized customized full solution surgical solutions. What should be paid attention to after surgery? Answer: After surgery, it is necessary to strictly follow the doctor's advice on medication, pay attention to eye hygiene, do not apply eye makeup for one month after surgery, do not wear contact lenses for three months, do not swim for six months, and do not dive for one year. Within one year after myopia surgery, 6 follow-up examinations should be conducted, including 1 day, 1 week, 1 month, 3 months, 6 months, and 1 year, to confirm the recovery of the eyes. Don't be lazy! Aier Eye Group is a professional medical institution that supports global remote re examination, so you don't have to worry about delayed re examination due to studying, working, or traveling.
