Are there any sequelae of femtosecond surgery, and are there sequelae of femtosecond surgery?

Audio content. ReLEx laser surgery uses a femtosecond laser to create a lens in the cornea and then remove the lens through a small incision. The whole process is a knifeless operation, all of which are carried out by femtosecond laser, and the incision is very small, some are only about 2mm.

However, any surgery is risky, and there may be postoperative infections and poor wound healing due to the possibility of reLEx laser surgery. In addition, since a lens is dug in the cornea, it takes a certain amount of time for the front and back layers to heal. In patients with ReLEx surgery, the recovery of vision or visual quality is slightly slower than that of other procedures, but with the extension of time, the visual quality will be basically the same as that of other procedures.

There are other risks, such as the risk of corneal decompensation, which is shared with other procedures called keratoconus. This kind of risk is very serious, which will lead to a persistent and irreversible loss of vision, so it is important to do a good job of preoperative screening and postoperative follow-up.

Are there any postoperative sequelae of myopia correction?

There is no need to worry about the after-effects of surgery.

First, refractive surgery is a corneal surface surgery, which will not directly lead to lesions and sequelae of other eye tissues.

Second, a detailed preoperative examination will be done before the operation to ensure that the eye meets the surgical requirements, and the doctor will operate on the patient;

Third, as long as the doctor's instructions are strictly implemented throughout the operation, there will be no rumors on the Internet about myopia surgery causing cataracts, retinal detachment, blindness, eye inflammation and infection, etc.;

Fourth, if refractive surgery does lead to serious complications and sequelae, will the state allow the procedure to develop so quickly?

Clause. 5. The laser used in the surgery is to scan the cornea accurately without harming the internal tissues of the eyeball. Excimer lasers are cold lasers that precisely ablate the portion of the cornea that is expected to be removed without damaging the surrounding tissues and other tissues.

The wavelength of the excimer laser is very short and only 193nm, so it cannot penetrate the eye at all, so there is no harm to the internal tissues of the eye***. There is also no reason for the recurrence of sequelae after a few years.

The possible sequelae of ReLEx are:

1. The corneal flap is off-center, the corneal flap is not in good alignment, the corneal flap is folded, and the corneal interlaminar debris or blood remains.

2. The laser cutting is off-center, and the corneal knife cuts through the cornea.

3. Postoperative lifelong glare and dazzling: myopia is more common in height, and there is halo when looking at things.

4. Under-correction or over-correction: This situation will require re-operation, and it is not ideal after re-operation.

5. Vision**: Especially for people with high myopia, vision begins to decline a few years after surgery.

6. Best-corrected visual acuity decline: After surgery, it is not possible to achieve the visual acuity that can be achieved with glasses.

7. Dyslexia, dry eyes, decreased corneal sensitivity, pain.

8. Irregular astigmatism: Almost all people who have myopia surgery have varying degrees of irregular astigmatism after surgery.

9. Corneal infection, diffuse interlamellar keratitis, formation of corneal insula.

10. Degeneration or scarring of the corneal periphery, corneal center pigmentation.

Although myopia surgery has been developed for 20 years and the technology is very mature, because it is a surgery after all, the current postoperative effects cannot be completely eliminated, so surgery is generally not recommended.

The best way to avoid surgery is to detect myopia in time**. Expert advice: In the early stage of myopia, as long as the bad eye habits are corrected in time, and combined with oral eye vision nutrients, it can be well controlled or improved for a period of time, and it can be done without adult surgery.

ReLEx lasers generally have no sequelae.

ReLEx laser myopia eye surgery is a type of lens removal with a micro-incision. The principle of femtosecond laser myopia eye surgery is to use the femtosecond laser to accurately focus in ultra-micro space, according to the patient's preoperative examination data, use femtosecond laser to make a corneal stromal lens of corresponding thickness and a tiny corneal incision, and then take out the corneal stromal lens through the tiny corneal incision, after taking out the corneal stromal lens, the refractive power of the cornea has been accurately reshaped, so as to achieve the purpose of correcting myopia.

The preoperative examination of ReLEx is the key to ensure the postoperative results of ReLEx. We can take a brief look at the preoperative examination items of ReLEx.

Unaided vision. Old mirror power.

Computerized optometry. Non-contact tonometry.

Corneal topography.

Axial length measurement.

Corneal diameter measurement.

Dominates ocular testing.

Anterior segment examination.

Sodium fluorescein staining.

Tear secretion test.

Dilated pupils. - Fundus photography, examination of the periphery of the fundus.

Optometry. Preoperative re-optics.

You don't have to worry too much about the problem of myopia after full femtoseconds. First of all, if it is simple myopia and there is no family history of high myopia, after the age of 18 and adulthood, if you do not overuse your eyes, myopia can stop developing and will not get worse. But.

If you go online, read books, look at your phone, and play games every day as an adult. If you don't pay attention to eye protection, myopia will still worsen.

At the same time, in the preoperative examination of ReLEx, the patient's age, myopia development, family history and other issues are thoroughly understood. Patients who may develop a rapid myopia after surgery are screened to reduce the occurrence of this condition. This also requires patients to pay attention to preoperative examinations and not deliberately conceal relevant information.

There are no sequelae of myopia surgery, as long as the contraindications to surgery can be found through examination, there will be no other problems with reasonable and scientific eye use after surgery. When people get old, all organ functions will deteriorate, and the eyes are no exception, such as cataracts, fundus lesions, etc., which are not related to myopia surgery. Southeast, Ophthalmology.

The sequelae of doing ReLEx are:1The corneal flap may be displaced, and it may also be lost.

2.Some patients may cause vision loss, or they may have watery eyes and bloodshot eyes. 3.

Corneal neovascularization may also recederate, infection, or foreign body residue may occur. Care after surgery is also very important, and it is important to pay more attention to eye protection.

The main disadvantage is that personalized cutting cannot be realized for the time being, but the current research direction has been available, and it is believed that in the near future, personalized design can be realized.

Myopia surgery itself is not something that everyone can do, it needs to be checked, and it can be done only if it is suitable for it, and the problems you are worried about can be eliminated during the examination. As long as you can do it, it's not a big problem.

Hello, the current excimer laser surgery is safe enough, but the conditions for surgery must be met. Common surgical risk sequelae are the following:

1. Dry eye syndrome is common.

2. There is a risk of refractive regression.

3. Glare, poor night vision.

4. Surgical infection can cause serious complications.

5. Keratoconus, once it appears, it is difficult to correct, the light one needs to wear RGP glasses, and the heavy one needs to do corneal transplantation.

Two years ago, I was in Kunming Huashan Eye Hospital, and I had a full femtosecond myopia laser surgery, and there is no problem with the follow-up until now. You can do it with confidence and don't be deceived by rumors.

Hello, dry eyes may occur, but the probability of occurrence is not too great.

Laser correction is to adjust the curvature of the cornea, and there are many types of surgery, so the most suitable one is selected according to the different corneal conditions of each person.

I did the ReLEx at the eye hospital called Peace. 575 degrees in the left eye and 600 degrees in the right eye. Astigmatism is almost 300. On the first day after surgery, there will be tearing and photophobia. The next day, there was no discomfort and I could use my eyes normally, and my vision was reached.

After surgery, there is a possibility of high myopia, dry eyes, decreased night vision and complications of glare, but it is not a sequelae that the probability of occurrence is not high. As long as you follow this medication on time, there is nothing wrong with regular check-ups. It usually takes one to three months to recover from the previous level!

If there is a danger that there will be sequelae, then the preoperative examination will not be qualified, and the doctor will not do it for you. Formal health care providers cannot afford this responsibility.

ReLEx surgeryThe entire operation is completed by femtosecond laser, no need for corneal lamellar knife to make corneal flap, no need to combine with excimer laser machine**, full femtosecond laser small incision stromal lens removal technology, no need to make corneal flap The femtosecond laser can be used to make corneal flap stromal lens and use small incision to complete the removal of its lens. It can reduce the damage to corneal nerve fibers, reduce the impact on corneal biomechanics, and improve the quality of vision.

In the whole process of ReLEx laser surgery, there is no need to make an open corneal flap or an excimer laser, but to use the ReLEx laser to completely shape the corneal matrix through two interlaminar blasts of different depths in the cornea, and then remove it through a small incision of 2-4mm to complete the operation. Since the "ReLEx" surgery does not require the production of a flip-open corneal flap, it is truly a "cutting" method for corneal refractive adjustment. Therefore, "full femtosecond" is more precise, safer, more comfortable than "half femtosecond" surgery, and the postoperative recovery is faster.

If you want to know more about ReLEx surgery, we recommend Guiyang Aier Eye Hospital. Aier Eye Hospital Group is a medical institution listed on IPO in China, and up to now, Aier Eye Hospital Group covers Asia, Europe and North America; At the same time, it has 3 listed companies in Chinese mainland, Europe and Southeast Asia, and more than 600 ophthalmology hospitals and centers, including more than 500 in Chinese mainland, with a total of more than 10 million consultations, providing a full range of ** for every patient.

If there are sequelae, there may be the following: 1. Dry eye syndrome: At present, the more common sequelae after myopia eye surgery is dry eye syndrome, especially for patients who have dry eye syndrome before surgery, the symptoms of dry eye syndrome after surgery may be aggravated and may become obvious, mainly because the patient has it before the operation, and the cornea has corresponding incisions after the full femtosecond surgery, and its morphology changes, and the secretion, shape and distribution of tears have changed abnormally, which will lead to the aggravation of dry eye syndrome.

Therefore, it is necessary to have regular follow-up visits after surgery, and apply the corresponding eye drops on time to improve the symptoms of dry eye syndrome. 2. Re-myopia: Some patients overuse their eyes after surgery, especially if they use their eyes for a long time, and re-myopia will occur, and they should follow the doctor's instructions and use the corresponding eye drops on time to ensure that the cornea heals at a normal rate, which is also one of the ways to prevent re-myopia.

3. Corneal infection: After the ReLEx laser surgery (i.e., ReLEx surgery), corneal infection and other symptoms may occur, and anti-infective eye drops should be used regularly according to the doctor's instructions after surgery to prevent corneal infection and cause some sequelae.

There is nothing to regret, in fact, everyone has some misunderstandings about myopia surgery, the operation is very safe, foreign pilots or celebrities have done it, this surgery is not a certain disease, just take off the glasses, then you can choose if you need to take off the glasses, if you are really worried, just bring glasses.

These factors should be taken into account before doing it, and since you have done it, you should face it, overcome your innermost thoughts, there is no regret medicine in the world, just work hard to overcome it.

There is no way to recover to the pre-surgery period if you regret it after myopia surgery. Once complications occur, they should be treated in time, such as postoperative infection and loss of corneal epithelium, which can be treated.

Hello, face, since you know that you are wrong, and you regret it so far, if it is an explainable ,.. that happened recently

Hello. There are basically two theories of sequelae, one is that it is easy to get cataract, but elderly cataract is an aging disease of the human body and has nothing to do with corneal myopia laser surgery. The other is that it is easy to get keratoconus, which is not valid, and keratoconus is a genetic disease and myopia surgery has nothing to do with it.

You can choose a large ophthalmology hospital with good equipment and specialists in ophthalmology, so that the results of the surgery ***.

The femtosecond laser LASIK procedure can eliminate almost all serious complications caused by corneal flap making. Based on the results of nearly 300,000 femtosecond LASIK surgeries that have been performed so far, no serious complications related to the surgery have been identified.

All patients who are suitable for LASIK surgery can undergo this surgery, and in the past, there are five types of people who cannot do traditional LASIK surgery can choose femtosecond all-laser surgery, and its scope has been expanded, mainly as follows:

1. In the past, 10% of patients who could not undergo LASIK surgery because of thin cornea and high myopia could undergo LASIK surgery with femtosecond laser flap.

2. In the past, people who could not make corneal flaps with mechanical metal knives because of small eye fissures, small corneal diameters, and flat corneas can also do femtosecond lasers.

3. Femtosecond laser is also the first choice for augmentation surgery after undercorrection and overcorrection after ordinary LASIK surgery.

4. This surgery is most suitable for patients who are afraid of cutting the cornea with a mechanical metal lamellar knife.

5. For those who have high requirements for surgical results, it is recommended to also do femtosecond laser.
