Whether the cornea can be regenerated after reLEx surgery to correct myopia

The refractive surgery process is shown below:

Refractive surgery removes the lamellar in the cornea, which has no regenerative function.

Hello, first of all, the myopia of the eyes can be reversed, it is recommended that you can pay attention to the suggestions that it will slowly improve in the future, and maintain the correct posture to read and read in the future, and use bear bile pills to clear the purpose, it is recommended that you do more eye exercises. You can look at things in the distance more and promote the adjustment of your eyes【Shanghai C-MER Ophthalmology】I hope the above reply can help you!

Hello, ReLEx surgery itself does not exist**.

1. First of all, there is a suitable group of people for surgery: the general requirement is that adults over 18 years old, with a stable myopia degree for more than two years (the annual increase in the degree does not exceed 50 degrees, it can be regarded as relatively stable), and the comprehensive examination data are suitable for it.

2. The operation is done in the third layer of the cornea (stromal layer), the characteristics of the stromal layer are non-renewable, generally speaking, the overall corneal curvature tends to be stable after surgery, and the effect of maintaining normal eye use after surgery is generally stable for life.

However, this surgery is equivalent to solving the problem of your existing stable degree, if you use your eyes with high intensity after surgery, it is not excluded that there is a possibility of myopia again, and the other point is that each person's corneal cell activity is different, some people have active cells, and the healing ability is super strong, plus the degree is relatively high (more than 600 degrees) does not rule out the possibility of regression, this possibility is relatively low probability, generally about 3%. Generally, it occurs within one month to one year after surgery, and the regression in the early postoperative period can be controlled with medication adjustment, so it is important to have regular postoperative reexamination.

In order to ensure the safety and effectiveness of the surgery, patients need to go through a series of preoperative examinations and screening. Including: visual acuity test, dilated mydriasis, corneal topography, external eye condition, refractive medium, pupil diameter, visual acuity to be corrected, etc.

Patients with high myopia are more likely to have fluctuating visual acuity after surgery, but it can be controlled at about 5% of the original power. Therefore, don't worry too much about men and women who plan to have surgery, as long as you choose a hospital with formal qualifications, pass strict preoperative screening, actively cooperate with doctors, and use your eyes regularly after surgery, regression is preventable and controllable.

Laser surgery itself generally does not cause myopia**, and most patients with simple myopia are stable after surgery and do not need to wear glasses. Some people have myopia again after laser surgery, mainly due to the fact that the myopia was not stable before the surgery. Especially for patients with high myopia, the myopia may continue to deepen, or corneal ectasia, keratoconus, glaucoma, etc., which is manifested as the need to wear myopia glasses again after surgery.

Therefore, surgery is not recommended for patients with an annual myopia change of more than 50 degrees before surgery, or for patients with autoimmune diseases, keratoconus, or pathological myopia.

No, under normal circumstances, patients who are required to undergo surgery are over 18 years old, and the development of myopia in the past two years is relatively stable, and the progression of the degree does not exceed 50 degrees per year. Femtosecond laser surgery for myopia is controlled by a computer, a concave lens is cut out of the cornea, and the molecular bonds between the corneal tissues are broken and vaporized by cold laser.

The surgery itself does not create a problem. Because laser myopia correction surgery changes the degree of corneal myopia is one-time, permanent and irreversible, there is no possibility of regression.

If there is a so-called "postoperative**" problem, it is actually not related to the operation itself, and other eye diseases should be considered, and it should be timely**.

Hello, it is said that all people with myopia are suitable for excimer laser correction surgery, mainly depending on the condition of the eye. Generally speaking, 4 conditions can be met:1

Be at least 18 years old; 2.The degree has been stable in the past two years; 3.Refractive stability for two years, good corrected visual acuity, no other eye diseases; 4.

Those who have no contraindications to surgery after examination. The regression of myopia is closely related to your later eye habits.

The time of myopia surgery varies depending on the type of surgery. The first one, excimer laser surgery, which is the earliest surgical method used for **myopia, because the trauma of the operation is relatively large, so the recovery time is relatively long, about 3-4 weeks after the operation can be stabilized, and it takes about 3 months for the cornea to heal completely. The second type, femtosecond laser surgery, which is currently the most widely used surgical method, because the surgery is less traumatic and the accuracy of the operation is higher, so the postoperative recovery will be faster, and the visual acuity can be restored to the state in 4-6 hours after surgery, and it can be restored to stability in about two weeks after surgery, which does not affect normal life at all.

The third type is intraocular lens implantation with phakism, which generally takes about a month to recover.

In general, the recovery time of femtosecond laser surgery is relatively short, and you can use your eyes normally after the follow-up examination on the second day after surgery. Although the recovery time for femtosecond laser surgery is fast, it takes 3 months to fully recover and reach a stable period. During this period, you need to pay attention to your eyes, follow your doctor's instructions, and have regular follow-up visits to restore the most perfect level of vision.

The preoperatively best corrected visual acuity can be achieved on the second day after surgery, and it takes one to three months to fully recover and stabilize.

The recovery period is one to three months, during which there will be a small fluctuation in vision, but there is no impact on normal work, study and life.

The effect of ReLEx surgery is relatively good, to a certain extent, it can effectively avoid the symptoms of eye discomfort, so it should be conditioned in time, after ReLEx surgery, we should pay more attention to rest and emotional conditioning, we should usually have a good life routine and self-care awareness, and we should have regular physical examinations, which can effectively avoid the phenomenon of serious infection and inflammation, and avoid the phenomenon of disease, and the recovery time of ReLEx surgery is about three months.

After laser surgery for myopia, under normal circumstances, the vision is stable after one month, and you can use your eyes normally and exercise normally.

However, the stability of postoperative vision is basically more than half a year, and during this period, it is necessary to correct bad eye habits, as well as oral oral administration of blueberry lutein every day to supplement the comprehensive nutrition of the eyes and fundamentally maintain the stability of postoperative vision.

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.

This is normal, no need for remedy, surgery may reserve a part of the farsightedness according to individual conditions, about 100 degrees, normal vision cornea without inflammation, you can consult the doctor who did your surgery.

"ReLEx laser"**myopia, surgery no longer requires the participation of excimer laser. At the same time as the corneal flap is made, the corneal part that needs to be eliminated for myopia can be made, so as to realize the true sense of bladeless surgery, combining flap making and laser cutting, so that corneal laser refractive correction surgery bids farewell to the scalpel. Tianjin Eye Hospital is the best hospital in the country for full femtosecond laser corneal refractive surgery.

The ReLEx laser surgery system is a revolutionary technology that is leading the way in corneal myopia surgery. Not only can the ordinary excimer combined with the flap femtosecond laser myopia surgery be completed, but also the full femtosecond myopia surgery can be realized, that is, the traditional excimer technology is abandoned, and the flap making to refraction are completely completed by the femtosecond laser.

The ReLEx laser surgery system is also the only surgical system among all femtosecond devices in the world that can carry out femtosecond laser myopia surgery. The accuracy of the operation has been greatly improved, the negative pressure during the operation is smaller, the operation process is more comfortable and fast, and the safety of myopia surgery has been guaranteed unprecedentedly.

With the smallest laser energy, a high degree of ZEISS optics focusing, and a high-speed emission frequency, the desired cutting depth can be precisely positioned and extremely high-performance.

Unique 3D stereoscopic cutting.

Visumax is a unique corneal surgery system with the ability to vary a wide range of cutting parameters. The intuitive software allows you to easily adjust patient-specific parameters. Thanks to innovative femtosecond laser technology from ZEISS.

Visumax is not only capable of femtosecond laser flap making, but also can be used in a wider range of clinical applications.

Larger** range.

VISUMAX is accurate in cutting, and the highest quality is extremely high, and the error of corneal flap thickness is greatly reduced. Therefore, it can be used in high-risk patients who have not been able to undergo surgery in the past. Become safer.

Gentle**:

The contact lens design of VISUMAX is unique, different specifications and sizes are suitable for different eyes, and it can also avoid the discomfort caused by the increase in intraocular pressure during the negative pressure suction process, and the intraoperative cooperation is better. This stable human cornea design delivers desirable results.

The Visulmax ReLEx Surgery System is the most advanced corneal refractive correction system at present, leading the trend and trend of corneal refractive surgery. Ordinary femtosecond laser can only be used for the production of corneal flaps, while femtosecond laser is a newer concept, which can not only make corneal flaps, but also complete the full femtosecond corneal stromal lens resection surgery, ensuring the "incision-free" state after surgery. The surgery is more precise and safer, with minimal biomechanical impact on the cornea, avoiding the occurrence of corneal flap displacement such as dry eye syndrome.

What are the advantages of ReLEx lasers?

1. Greatly reduce the risk of surgery.

2. It has high accuracy, and the thickness and shape of the corneal flap are uniform.

3. Trapped-type corneal flap, more accurate reduction.

4. It is not affected by corneal curvature, and the correction range is wider.

5. It relatively avoids the first-class contamination of the medical source.

6. The postoperative visual quality is more perfect.

Yes, you can bend. Instead of making a corneal flap, the femtosecond laser surgery is performed on the stromal layer of the cornea at different depths twice, forming a stromal lens into a micro-incision of 3 to 4 mm.

Laser correction of myopia is currently the most advanced surgical method for myopia, the effect of the operation is very good, as long as the detailed eye examination, excluding the contraindications of surgery, you can completely correct the myopia next to the open limb, so that the vision can reach normal.

ReLEx laser surgery can completely correct vision, and the eyes can no longer be used in an irregular manner after surgery. Otherwise, it is still possible to become myopic again.

Theoretically, femtosecond surgery can correct myopia at 50 degrees to 1000 degrees, and astigmatism below 500 degrees.

First of all, you should be clear that strict, comprehensive and professional preoperative examination is the first prerequisite for improving the safety of myopia surgery. Through the preoperative examination, we can know the thickness of your cornea, corrected visual acuity, estimated postoperative visual acuity, dry eye, and whether there is fundus disease.

Secondly, the equipment for preoperative examination is also the top priority, we use Carl Zeiss examination equipment, Opel ultra-wide-angle fundus photography equipment, you can clearly see whether you have fundus problems. If there is a fundus problem, it is necessary to solve the fundus problem first, and then you can do myopia surgery.

Regarding the recovery period of Quanfei virtual code laser surgery, there are also many children's shoes will ask. Generally speaking, if you have a complete femtosecond laser surgery, there will be a layer of fog in front of your eyes on the day you do it, just like that kind of plastic wrap, a transparent fog feeling, and this phenomenon will probably disappear in the next day, so you don't have to worry. In addition, there may be eye soreness on the day after surgery, so be sure to rest well.

In general, the recovery period of ReLEx laser surgery is about 1 week, and the fog and vision mentioned above can generally be restored the next day.

Okay, I'll tell you about it today, I also did ReLEx on April 20th, and after the surgery in the morning, the soreness in the eyes disappeared in almost 2 hours in the afternoon, and the vision was already there that day. The feelings involved in the article are all my real experience of taking off the lens, and I hope it will be helpful to those who do ReLEx.
