Is there an expiration date for laser vision correction?

You misunderstood, it does not refer to the expiration date, because since the advent of laser correction surgery, there has been no serious regression of primary vision in the past ten years, LASIK stands for Excimer Laser in Situ Keratomileusis, which is a combination of microplate keratomlasty system and excimer laser, which has opened up a new field for the correction of myopia, farsightedness and astigmatism. The method is to open a corneal flap with a corneal microplate plasty system, and use an excimer laser to precisely cut the corneal stromal layer under the flap according to the degree of myopia and astigmatism. This method preserves the corneal epithelium and Descemet's layer, so it is most in line with the anatomy and physiology of the cornea, and is the most advanced refractive error technology in the world today.

At present, as long as you pay attention to prevent traumatic damage (such as collision, rubbing, etc.) after surgery, resulting in the displacement of the corneal flap, pay attention to eye hygiene like normal eyes, and protect your eyesight, you will not easily become myopic again!

It's not like you think you'll have normal vision within 10 years, but if you don't do the same consistent eye care after force correction surgery, I think you'll be back to your original shape in 2 years. (And I've thought about going for this kind of surgery, huh.) If you take good eye care measures, you may have a bright window to your soul in the coming days.

Although some surgical patients may experience glare, reduced night vision, etc., these are reactions that will be clearly informed before surgery, and for most people who undergo surgery, these *** are completely within the tolerable range, so don't worry. Moreover, excimer laser surgery does not have any defects to the internal tissues of the eyeball, and the surgery is only performed on the surface of the cornea, so there is no reason for sequelae to appear after several years.

The safety of the operation can be guaranteed as long as it passes a strict examination before the operation; It has been more than 20 years since the surgery was first performed, and it is now very mature, with tens of millions of people having successfully undergone surgery. At present, there are no adverse sequelae, but this is also related to the choice of hospital doctors and the advancement of instruments and equipment. Therefore, if you are considering doing it, it is recommended to choose a regular hospital.

To put it bluntly, laser vision correction is a minor operation, and it has a variety of surgical methods, among which the femtosecond surgery is the most advanced. As long as it is a regular ophthalmology, it will do a full range of eye examinations, such as eye power, corneal thickness, etc. Only those who meet the requirements of the surgery can be lasered, and there are few postoperative complications (mild dry eye, many normal people also have it - poor eye habits and excessive eye use) or none.

The sequelae that people generally talk about should be the increase in the power caused by excessive eye use after surgery, that is, the eyes are undercorrected and they cannot see clearly.

Although the appropriate age for surgery is 18-40 years old, the best age for surgery is around 25 years old.

If you just turn 18 years old, it is better to postpone the surgery, personal opinion;

Usually after surgery, there will be mild myopia**, sensitivity to bright light and easy dry eyes.

Hello, laser surgery is a very mature technology at present, as long as it is a regular eye hospital for systematic and formal eye detection, and meets the requirements of laser surgery, surgery can be performed. Moreover, laser surgery is only performed on the stromal layer of the cornea, as long as the cornea is thick enough, there will be no risk, there may be temporary dry eyes, etc., according to the doctor's prescription for eye drops.

At present, myopia laser surgery has been relatively mature, and it is impossible to talk about what it has, there may be discomfort, or complications may occur, of course, it is a matter of probability. The most common is dry eye, which may feel dry after surgery and may be severe. This condition may be alleviated with eye drops such as sodium hyaluronate, sodium hydroxymethylcellulose, including Hyrue and Shawway.

If the cornea is thin and high before surgery, there may be less cornea left after surgery, which may cause corneal decompensation, and vision will become worse and worse after decompensation. Of course, this probability is very small, basically a few thousand.

1. The probability of 1 in 10,000. If you continue to use your eyes for a long time after surgery and your eye habits are poor, you may also be nearsighted. There is also the possibility of poor night vision or glare at night, which will gradually improve with the prolongation of the postoperative time, and generally does not affect life.

The postoperative effects are:

1. Postoperative undercorrection, regression, and vision loss should not be ignored.

2. Halo and night vision may occur after surgery.

3. Dry eyes.

4. Complicated by severe keratitis.

5. Corneal flap dehiscence caused by accidental collision after surgery.

Myopia surgery has been developed for 20 years, and the technology is quite mature, but because it is a surgery, it is risky, so it is still necessary to be cautious.

And myopia surgery must be clear: myopia surgery must be over 18 years old, myopia degree between 100-1500 degrees, stable vision for more than two years, no other eye diseases, after a detailed preoperative examination, can be carried out myopia surgery.

Generally, children under the age of 18, because they are in the period of vision development and have strong eye adjustment, myopia can be restored by taking drugs to reduce the degree of myopia. It is recommended to take Leyan Vision Nutrients, twice a day, one pack each time, take it with warm water, and insist on taking it for a period of time, the myopia degree will gradually decrease, and it will avoid the trouble of surgery in adulthood!

I have a friend who has done it, one friend has been doing laser for more than 3 years, and she feels very good, and 2 have been doing it for 1 year, saying that now her vision is slowly starting to see a little clearly.

Laser surgery for myopia can restore the level of corrected vision that existed before surgery.

How much is the corrected visual acuity before myopia surgery, and how much can be recovered after surgery, such as the corrected visual acuity before surgery, and the above can be achieved after surgery. If the corrected vision before the surgery is only, it will not be achieved after the operation, only is. The surgery only changed the method of wearing glasses, not to address the nature of myopia.

Corrected vision before surgery is not good, and vision after surgery will not be good. Myopia eye surgery requires normal or higher corrected visual acuity and stable power before surgery.

Myopia eye surgery has simply changed the way to wear glasses. The surgery is to make the lens on the cornea, or implant the lens into the eye key closure to achieve the purpose of information search to correct vision.

After myopia eye surgery, you should use your eyes correctly, avoid excessive eye use, develop good eye habits, and avoid further increase in power and further decline in vision, resulting in vision regression.

Everyone's vision is different, and the vision that can be restored from myopia surgery is also different. Generally, how much you can correct your vision with glasses will recover after myopia surgery.

However, this corrected vision is foot correction vision, and many people wear glasses that do not match their myopia degree, so self-corrected vision is generally not up to the best so this corrected vision depends on the corrected vision during the hospital examination.

Just like before I had myopia surgery, I could barely reach the monocular vision with glasses, but when I did the preoperative examination in the Taixue Ophthalmology Department of Suzhou BenQ Hospital, Zheng Ayuan's check, the visual acuity was checked in detail, and the corrected vision measured by the doctor was that my vision was really restored after the operation.

There are always harms, but in general there are still effects, it's up to you to think about it.

There are three main types of myopia laser correction methods, namely full femtosecond surgery, half femtosecond surgery and superficial surgery. ReLEx surgery uses a femtosecond laser to create a lens in the corneal stromal layer and remove the lens through a small incision of about 2 mm, thereby correcting myopia and improving vision.

If there is a decrease in vision in the eye, Shanghai Preh Eye Hospital suggests that the method of restoring vision depends on the specific disease.

It is very important for everyone to choose the surgical method carefully and choose the surgery carefully, after all, not every surgery can be successful, most of the surgeries we can see today have some accidents, of course, it is still rare to be able to recover to a very healthy condition, so it is more necessary to be cautious in the process of choosing surgery.

Laser correction of vision, in fact, will be a little harmful, but relatively speaking, its *** is still relatively small, as long as you go to a regular hospital for correction, there is no problem.

There is no harm. Laser vision correction is a safe and effective minimally invasive technology with a small traumatic surface and negligible harm.

Laser vision correction must have certain dangers and harms, it will make the cornea thinner, and then this surgery can only be done once in a lifetime, and you must protect your eyes after doing it.

Every type of surgery has certain risks, and some people may be nearsighted through femtosecond laser surgery, which is relatively common. However, some people have some sequelae after surgery, such as eye pain, dry tears, and may also have vision loss, double vision, blurred vision or eye pain, which will cause some damage to people's eyes.

If people experience sequelae after femtosecond laser surgery, they should be targeted**. If there is a disease such as keratitis, you should use some anti-inflammatory and antiseptic eye drops**, and you can also take some oral antibiotics for conditioning. Some people may have dry eyes, they should supplement more trace elements in the body, drink more water, not fatigue their eyes, and do not face electronic products for a long time.

In view of the sequelae of femtosecond laser surgery, in addition to long-term effectiveness, people should also maintain a good diet, eat more protein-rich foods, should supplement the body's calcium and phosphorus, and need to supplement the body's vitamins. People with sequelae should have regular check-ups after surgery, should not use cosmetics, should reduce the time spent reading, and should not go swimming.

It can be seen that femtosecond laser surgery is a more effective method for myopia, so many people will take this kind of surgery, but there may be some sequelae after surgery, specifically manifested as eye pain, dry tears, vision loss, etc., eye drops or some antibacterial drugs can be used, you should maintain a good attitude, and supplement the body's trace elements.
