How about femtosecond treatment for myopia? I am mainly worried about repeated postoperative vision

If the surgery is done well, it will not **, a friend of mine spent 10,000 yuan for surgery, and now he has not seen him wear glasses for more than three years, and his eyesight is better than that of ordinary people!

The ophthalmology experts of Jiangxi Nanchang Purui Eye Hospital are here, femtosecond laser is used to make corneal flaps in LASIK myopia surgery, and its biggest advantage or specialty is that it makes corneal flap thickness with very high accuracy. Its accuracy (average fluctuation in: 10 15um) is 3 times that of lamellar knife accuracy (average fluctuation in 30 45um), and the actual probability of corneal flap complications is tens of thousands of times lower.

1. Femtosecond laser LASIK myopia surgery is an all-laser LASIK surgery that uses femtosecond laser to do corneal flap. Since it does not require a mechanical blade to make a flap, femtosecond laser LASIK surgery can eliminate almost all serious complications caused by corneal flap making. 2. The biggest advantage or specialty of making a corneal flap in femtosecond laser LASIK myopia surgery is that it makes a very high accuracy of corneal flap thickness.

Its accuracy (average fluctuation in: 10 15um) is 3 times that of lamellar knife accuracy (average fluctuation in 30 45um), and the actual probability of corneal flap complications is tens of thousands of times lower. In addition, the negative pressure of the suction ring used to make a corneal flap with femtosecond laser (about 35 mmHg) is significantly lower than that of a corneal flap made with mechanical lamellar knife (about 65 mmHg).

Therefore, the use of femtosecond laser to make corneal flaps can greatly improve the surgical safety of excimer laser **myopia, especially for patients with thin cornea, large variation in corneal curvature and high myopia. Femtosecond laser is safer to make corneal flaps What is the connection between excimer laser and femtosecond laser? The femtosecond laser production of corneal flaps can be completed by laser scanning according to the parameters set by the physician, which completely avoids the abnormalities of various flaps that may occur in mechanical keratomilene knife flaps, reduces complications such as iatrogenic aberration and cross-infection, and greatly improves safety.

Because the accuracy of the corneal flap made by femtosecond laser is very high, which is 100 times that of the mechanical corneal lamellar knife, the thickness of the corneal flap is completely uniform and consistent, and the thickness, diameter, shape of the corneal flap and the position and width of the corneal flap pedicle can be flexibly set to generate a corneal flap suitable for the patient to undergo the next step of quasi-fractional laser cutting. The corneal flap made by the laser is well covered and not easy to displace, with extremely high accuracy, very low surgical risk, and faster healing recovery after surgery, thus forming the surgical characteristics of femtosecond laser, which makes the surgical effect significantly improved.

8 Advantages Efficient Casting Perfect Clear Vision Higher safety All-laser bladeless surgery completely avoids the surgical complications that may occur when making a corneal flap with a metal knife. More stable biological properties Fewer epithelial implants Fewer postoperative dry eyes Better surgical results Personalized design of corneal flap parameters to produce a highly accurate uniform and smooth corneal flap Reduce astigmatism triggers, reduce the generation of higher-order aberrations, and bring better visual results.

We all know that there are more and more people with myopia now, when many friends who want to take off their glasses are still deciding whether to have myopia surgery, but some people decisively choose to go for myopia correction surgery, and some people regret it after surgery, so why do they regret dying after reLEx myopia eye surgery? Let's take a look at it with the questions.

First of all, the whole process of femtosecond laser myopia correction surgery uses a laser to make a microlens in the corneal stromal layer, and then the lens can be removed through a 2-4mm incision to achieve the purpose of myopia correction, and the whole process can be completed in 3-5 minutes. People go through a detailed and rigorous preoperative examination by the doctor before surgery, and only after passing the examination can the operation be performed. In addition, the preoperative examination can accurately predict the visual effect after surgery.

If the preoperative vision is not stable enough, or if the anterior diameter of the eyeball is still in a state of change, the operation cannot be performed, and if the surgery is still performed at this time, it is likely that people will regret it.

However, after surgery, you can maintain good vision by taking medication on time according to the doctor's instructions and maintaining reasonable eye habits, and the degree of myopia is generally not **. Finally, after complete femtosecond myopia eye surgery, you need to do fixation training, cover your eyes with one hand, put the other hand in front of your uncovered eyes, stare at your fingers, hold for half a minute, and repeat the above actions on the other side.

Femtosecond laser myopia eye surgery is a "revolutionary breakthrough" in refractive surgery, and patients must undergo the examination of experienced and skilled physicians and adequate preoperative preparation, otherwise the risk of surgery will increase, and patients should pay attention to their own conditions in time after surgery

With the current technology, femtosecond surgery is very effective, and the postoperative recovery is relatively fast.

Although there is only a one-word difference, these are two completely different surgical methods, with different equipment and different processes, each with its own advantages. Femtosecond myopia surgery is a two-step procedure in which a femtosecond laser is used to create an open corneal flap and an excimer laser is used to cut the corneal stromal layer. ReLEx myopia surgery does not require flap making, and the femtosecond laser is used to scan the corneal stromal layer directly at two different depths to form a complete convex lens-shaped corneal tissue, while a 2-4 mm arc incision is made at the edge to remove the corneal tissue.

Due to the non-valvular minimally invasive, the incision is 80% smaller than that of the half-femtosecond, the flapless is minimally invasive, the postoperative dry eye is mild, and the corneal biomechanical stability is relatively high, which is suitable for people who love sports with regular corneal morphology. Semi-femtosecond surgery can be customized, with high precision of excimer laser, smoother cutting surface, and good postoperative visual quality, which is suitable for patients who need a personalized surgical plan with relatively irregular corneal morphology before surgery. There is no good or bad between the two types of surgery, only suitable and unsuitable, and after strict preoperative examination, what suits you is the best.

However, comparing which effect is better depends on the patient's individual situation. If the power is moderate, for example below 500 degrees, and there is no noticeable irregular astigmatism, the full femtosecond effect is better. There is no corneal flap in the whole femtosecond system, which is less traumatic and has little risk in the later stage.

If the shape of the cornea is not very regular, or if the astigmatism is relatively large, the prescription will be relatively high. It is recommended to choose a femtosecond laser, especially a personalized femtosecond surgery, which will have a better effect on such patients.

The occurrence of secondary myopia after myopia surgery has a lot to do with postoperative recovery and postoperative maintenance.

If you want to have poor vision after myopia, postoperative maintenance is very important. It should be noted that:

1. Correct bad eye habits and try to look less at electronic products;

2. Insist on doing eye exercises every day, and you can do them whenever you have time;

3. Ensure that there are certain outdoor activities every day and see more green plants;

Hello, ReLEx generally regains the best vision the next day at the earliest.

Some recover a little slower for a week or so, which varies from person to person.

Don't get too nervous.

You can use your eyes to work and study normally the next day after surgery, but we should also pay attention to the protection of our eyes and pay attention to rest. If you do not develop good eye habits and do not pay attention to eye hygiene, excessive use of your eyes will also affect the effect of surgery, and will make myopia occur again, so after the operation, in addition to paying more attention to rest, we should strictly control the time of watching computers, watching TV and mobile phones, if the time is too long, it is easy to cause visual fatigue, it is best to rest every 40 minutes for 5 to 10 minutes, which can effectively alleviate visual fatigue. Proper relaxation and rest of the eyes can also effectively prevent dry eye syndrome.

For femtosecond laser myopia surgery, the postoperative vision may fluctuate within 1-3 months, and some people will see near and far clearly, which will generally improve in about 2 weeks and stabilize the vision in about 3 months. Optimal visual stability can be achieved in half a year. After surgery, you must pay attention to eye maintenance, don't stay up late, play with mobile phones and computers for a long time, and do eye massage.

It usually takes 1-3 months for your vision to stabilize after surgery.

Myopia laser surgery is corneal refractive surgery, and the degree of myopia tends to stabilize after the age of 18. If you do not want to wear contact lenses or frames, you can consider laser surgery, which changes the shape of the corneal surface by cutting part of the corneal tissue to correct the refractive state of the eye. At present, corneal refractive surgery can be divided into full femtosecond, half femtosecond and excimer laser surgery.

As long as the preoperative examination is completely normal and there are no obvious contraindications to surgery, such as keratoconus, glaucoma, iridocyclitis, and severe dry eye, surgical correction can be considered within a certain range. With the advancement of surgical technology, the trauma to the cornea is also getting smaller and smaller, such as the incision of the ReLEx surgery is very small or even only 2mm, and the corneal structure is inflammatory, and the postoperative recovery is fast, and there is no pain, dry eye and other discomforts. In addition, normal vision can be achieved on the second day after surgery, and you only need to rest for 3-4 days to live a normal life, but you need to avoid eye compression and heavy physical exercise, so it takes about a week to recover from myopia laser surgery.

My friend did it some time ago in the southeast and he said it was clear the next day, but the doctor told him that it would take 3 to 6 months to get back to full stability.
