How to do femtosecond surgery and how long does femtosecond surgery last

All kinds of laser myopia surgery need to make a corneal flap first, and then open the corneal flap for excimer laser cutting, and finally restore the corneal flap to complete the operation, the difference between different surgeries lies in the thickness of the corneal flap and the different tools used to make the corneal flap. In addition to the traditional lamellar knife, femtosecond lasers are also a type of corneal flap that is thinner and smoother. Either way, the flap is cut, and the excimer laser is ultimately required to cut the patient's power.

The da Vinci femtosecond laser emits laser at a frequency of up to 1000k hertz or more, and the cutting accuracy is proportional to the emission frequency, and the cornea is cut vertically and horizontally to make a thinner corneal flap. In addition, there is a kind of full femtosecond on the market, which is basically a conceptual hype, and there are only a few installed units in the world, and the second operation is also more complicated, and the operation is not as fast as Da Vinci femtosecond.

At present, there are many surgical methods for myopia, including corneal refractive surgery and intraocular lens implantation surgery. As long as there are no contraindications to the examination, both types of surgery are acceptable. Corneal refractive surgery includes LASIK, LASEK, TRANS-PRK, Half Femtosecond, Full Femtosecond, etc.

This type of surgery is performed by cutting the cornea to correct myopia, so it is necessary to complete the corneal thickness, corneal topography and other related examinations. For patients with ultra-high myopia, or a thin cornea, intraocular lens implantation surgery may be considered.

If you take good eye care, you will generally maintain it and will not be myopic again.

Especially in the first week after surgery, it is a critical period of recovery, so don't be careless about some things that need to be paid attention to! You will be taught before, during, and during the operation. The preoperative examination will give you an estimate of your postoperative vision, which can generally be achieved in between.

The expiration date of the ReLEx procedure is as follows:

If the patient is an adult, that is, the age is 18 years old or above, the prescription is relatively stable, after careful examination before surgery, it meets the requirements of the operation, the selection is reasonable, the operation is smooth, the postoperative vision recovery is good, and the validity period is very long.

However, due to the fact that after the surgery, each person's situation is different, myopia deepens, eye lesions, and vision loss are caused, and the persistence is not so long due to personal factors, so it is important to have regular follow-up after surgery.

Myopia laser surgery is a laser in the stromal layer of the cornea, and the stromal layer is a non-renewable layer, and the part of the cornea surface flattened by the excimer laser will not regenerate and become convex, so the effect is very stable, and myopia will not reappear after surgery.

However, if you do not pay attention to eye intensity and eye hygiene after surgery, you may have myopia of no more than 20% of the distance and near power, but after checking out the specific cause, the hospital still has a way to give the most perfect and safest measures.

Taking off the mirror becomes "white rich beauty", and the life of hanging begins with taking off the mirror to become beautiful.

Generally speaking, surgery is recommended only when the prescription increases within 50 degrees per year. In the later stage, the power will still increase, so the main thing is to rest to prevent eye fatigue, so that the growth of the eye power can be slowed down or even not felt, so how long it can be maintained mainly depends on whether your eyes are healthy.

It is also beneficial to reset the power of the eye, on the one hand, the power is too high in the future to do full femtosecond surgery. On the other hand, it can effectively improve the quality of life, because myopia and non-myopia see two worlds.

In many people's imagination, it takes a long time to have an operation, but this is not the case with full femtosecond and half femtosecond surgery. ReLEx and femtosecond surgery are minimally invasive surgeries, the time is very short, the whole operation, femtosecond is about six or seven minutes, half femtosecond is about ten minutes, of course, it also depends on the cooperation between the patient and the doctor and the doctor's professional and technical level.

It's pretty fast, just ten seconds for one eye. I did it in Taixue Ophthalmology, and Dr. Dong Yuan's skills are great!

As of December 7, 2019**Femtosecond laser surgery for myopia may vary in different regions and hospitals. Generally, the ** of femtosecond laser surgery for both eyes is about 15,000 yuan.

Femtosecond lasers are characterized by very high instantaneous power, which can reach petabillion watts, which is 100 times more than the total power generated in the world today. A third feature of femtosecond lasers is that they can focus into areas of space smaller than the diameter of a human hair, making the electromagnetic field several times stronger than the force exerted by the nucleus on the surrounding electrons.

In the medical field, femtosecond laser can be used as an ultra-precision surgical scalpel, which has been successfully applied in the field of ophthalmology, and is used to make corneal lamellar flaps in excimer laser**myopic eyes, as well as other corneal surgeries.

The cost of a femtosecond surgery can range from 10,000-20,000, but the choice of myopia surgery requires a comprehensive preoperative examination to determine. In Aier Ophthalmology, a myopia surgery, 2-hour preoperative examination, intraoperative expert technology, advanced equipment guarantee, postoperative recovery and lifelong health management, during which at least 20 medical personnel are required to participate in the [**Appointment of ophthalmology expert number source].

Before doing femtosecond surgery, you need to complete the eye examination to understand the specific situation, and only those who meet the conditions can perform the surgery. The cost of femtosecond surgery is not cheap, so in order to ensure the results, you must choose a regular eye hospital.

The conditions that need to be met to do femtosecond.

1. The first is the age requirement. The age suitable for surgery is generally between 18 and 50 years old. Because adolescents under the age of 18 have immature eye development, the degree of myopia is unstable, while elderly patients over 55 years old are often accompanied by cataracts and other eye lesions.

2. The second is the requirement of myopia. Patients who are suitable for femtosecond should have a myopia degree of more than 100 degrees, and the maximum height number can generally reach 1200 degrees. However, the actual degree that can be corrected by each person depends on the thickness of the individual's cornea.

If you want to have femtosecond surgery, we recommend Aier Eye Hospital. Aier Ophthalmology is the first IPO-listed ophthalmic medical institution in China, with institutions in China, America, Europe and Southeast Asia, and its 780+ chain ophthalmology hospital centers; At present, it is a chain of professional ophthalmic medical institutions covering 32 provinces, autonomous regions and municipalities directly under the central government in China, with an annual outpatient volume of more than 10 million and a myopia surgery volume of more than 3 million.

It consists of ten ophthalmology subspecialties (refractive surgery, optometry, cataract, glaucoma, cornea and ocular surface, fundus disease, lacrimal disease, blepharopathy and oculoplastic surgery, orbitopathy and ocular tumors, strabismus amblyopia and pediatric ophthalmology), with an annual outpatient volume of 10 million person-times, and a professional and excellent medical and technical team with many doctors, masters, and chief physicians with rich surgical experience in coccyx management. <>

At present, there are two main methods of femtosecond surgery for myopic eyes: the first is half femtosecond surgery, and the cost of the operation is about 8,000-12,000 yuan. The second is full femtosecond laser surgery, the whole process of the operation uses femtosecond laser to shoot, the cost of the operation is about 20,000 yuan, the trauma of the operation is very small, and the accuracy of the operation is very high, so the visual quality after the operation is also better.

If there is myopia in the eye, myopia within 1500 degrees can be considered with femtosecond laser surgery**. The principle of this surgery is to change the thickness of the cornea by cutting the stromal layer of the cornea with a femtosecond laser, which can correct the refractive error, improve vision, and achieve the purpose of removing glasses.

Femtosecond costs about 9,800 yuan to 13,800 yuan, and it needs to be decided according to the type of femtosecond surgery. Femtosecond surgery mainly includes half femtosecond surgery and full femtosecond surgery, the cost of half femtosecond surgery is relatively low, about 9,800 yuan, and the cost of full femtosecond surgery is relatively high, about 13,800 yuan. After surgery, you should take more time to rest and reduce the time you spend using electronic devices.

The price of femtosecond surgery is usually about 10,000 yuan. This procedure can be performed at an ophthalmologist**, but only after the procedure must be done without any problems with the examination. If there is inflammation in the eye, or there are other eye diseases, the operation can only be performed when it is completely completed, otherwise it will also affect the effect of the operation.

The ** of full femtosecond surgery is generally about 2,000 yuan to 10,000 yuan, and the specific ** will vary according to the ** area.

This hospital is different, the equipment is different, the individual is different, etc., so you have to go to the hospital where you did the surgery to consult, and there are some examination items that are different from hospital to hospital, so asking here is only an approximate range.

It is best to meet your own conditions, Linyi Aier, and the doctor will formulate a plan according to your actual situation.

ReLEx is a popular laser correction surgery for myopia, and it is also the latest surgical method, and its main advantage is minimally invasive. It is a process of making a micro-incision of two to three millimeters, then cutting off the prescription and removing it. So, are there any drawbacks to ReLEx surgery?

ReLEx laser surgery is a minimally invasive surgery for myopia that is computer-controlled, reducing damage caused by irresistible mechanical factors. The principle of ReLEx laser surgery is to change the refraction of the lens, mainly to cut the retina with a laser, the shorter the cutting time, the higher the accuracy of the incision, its incision is two millimeters, and the recovery of ReLEx laser surgery is also better after surgery. If you want to remove your glasses completely, you can opt for ReLEx laser surgery.

ReLEx myopia surgery requires more than 20 strict preoperative examinations before surgery to rule out contraindications and potential eye problems, so as long as it can be done through preoperative examination, it is safe and reliable. The effect is remarkable.

Sharing of postoperative feelings of patients undergoing ReLEx laser myopia surgery.

Overview: Ordinary laser surgery or wearing glasses to avoid the increase in eye power These two methods are the traditional practice of myopia, but now there is a new method, which can be effective for myopia, this method is femtosecond laser myopia surgery, femtosecond laser myopia surgery is a new surgery, this surgical method was listed in China in 2011, femtosecond laser myopia surgery is very safe, and the clinical effect is also very good.

Step Method:

1 After the myopic patients have undergone the full femtosecond laser myopia surgery, they will soon be able to see things, and the phenomenon of people seeing things blurred before the operation will also be changed, and the things they can see are relatively clear, and the time for the full femtosecond laser myopia surgery done by the myopic patients is not particularly long.

2 If people want to have ReLEx laser myopia surgery, they need to be in a state where their power is particularly stable, that is, if their power has not increased significantly within two years, they can do ReLEx laser myopia surgery.

3 ReLEx laser myopia surgery has high precision, and postoperative safety, myopic patients have undergone femtosecond laser myopia surgery, few patients will have dry eye problems, and myopic patients can completely get rid of glasses after reLEx laser myopia surgery, and there will be no ** situation.

Precautions. ReLEx laser myopia surgery is actually a kind of surgery without knife and flap, and according to statistics, more and more patients are using ReLEx laser myopia surgery, which brings convenience to their lives after the surgery.

Femtosecond surgery is divided into full femtosecond laser surgery and half femtosecond laser surgery. The ** of ReLEx laser surgery is generally about 18,000 yuan. The ** of femtosecond laser surgery is generally around 8,000 yuan to 12,000 yuan. [10s to test which correction plan is suitable for me].

Myopia laser surgery has been used in ophthalmology clinical work for decades, with mature technology and high safety. At present, femtosecond laser is generally used in China, and full femtosecond laser surgery and half femtosecond laser surgery are usually used. The former has a fast postoperative recovery, fewer complications but also has certain limitations, low-grade myopia is not the first choice, and femtosecond cannot be used for farsightedness, etc., generally around 18,000 yuan.

If the conditions are not met, it is recommended to use half femtosecond laser surgery**, which is generally around 8,000 yuan to 12,000 yuan. If the degree of myopia is too high, such as more than 1000 degrees, the thickness of the cornea is too thin, and it may not be suitable for myopia laser surgery, and it is necessary to choose the myopia surgery method with intraocular lens implantation.

If you want to know more about femtosecond surgery, we recommend consulting Beijing Mingshi Ophthalmology. Founded in 2011, Beijing Mingshi Eye Hospital has been focusing on the professional medical field of myopia for 11 years, providing all-round and personalized myopia solutions for myopia people of different ages and different needs.
