How to explain glare after myopia eye surgery?

There are three reasons for glare after myopia laser surgery

1. The diameter of the pupil under the dark room is large, even if a large optical drive is designed during surgery, it cannot completely cover the pupil under the dark pupil, resulting in glare.

2. Femtosecond laser correction of myopia, when high myopia, the cornea is cut, and the deeper the "depression" formed on the surface of the cornea, the greater the slope;

3. During surgery, glare symptoms will also occur when the optical drive design is smaller than the diameter of the pupil under the dark light of the surgeon;

4. The patient does not cooperate well, resulting in eccentricity and dazzling.

Postoperative glare is generally directly related to the size of the aperture setting during the operation, and in general, glare will occur when the aperture setting is small, so it is important to formulate the surgical method.

After myopia laser surgery, the cause of glare after surgery is due to three reasons

1. The diameter of the pupil under the dark room is large, even if the college optical drive is designed during the operation, it cannot completely cover the pupil under the dark pupil, forming glare.

2. Femtosecond laser correction of myopia, when high myopia, the cornea is cut, and the deeper the "depression" formed on the surface of the cornea, the greater the slope;

3. During surgery, glare symptoms will also occur when the optical drive design is smaller than the diameter of the pupil under the dark light of the surgeon;

4. The patient does not cooperate well, resulting in eccentricity and dazzling.

Most of the causes of glare are related to the size and power of the dark pupil, and the probability of glare can be minimized through detailed examination and selection of appropriate surgery before surgery. In the early postoperative period, some people experience glare because the wound has not fully healed after myopia correction surgery. However, there is no need to worry about the fact that such conditions will gradually disappear within 1-2 months after surgery.

After laser surgery for myopia, the eyes will be weaker and more sensitive to glare, so it is recommended to wear a pair of anti-glare glasses.

There are many people who also have glare before myopia surgery, but they don't notice this, the glare will be aggravated after refractive surgery, but with the extension of time and the repair of wound tissue, this glare phenomenon will get closer and closer to the state before the surgery.

Femtosecond laser corrects myopia, and when there is high myopia, the cornea is cut, and the deeper the "depression" it forms on the surface of the cornea, the greater its slope. Glare can also occur when the time drive design is smaller than the diameter of the surgeon's pupil in the dark light of the surgeon. If the patient does not cooperate well during the operation, it will cause eccentricity and dazzling.

The reason for the glare after myopia surgery is also related to the wound and the large pupil at night, the pupil will gradually become smaller with age, and most of the early glare will disappear within three months to six months, which does not have much impact on the human body.

Many people will experience glare after myopia surgery, which is mainly related to the wound and the large pupil at night. After surgery, the pupil will gradually become smaller with age, so most of the early glare will disappear within three months to six months, but this glare will gradually subside with age, and it will not have much impact on the human body.

Hello, glare after myopia laser surgery is a normal manifestation, generally it can return to normal in 1 to 3 months, if the recovery is fast, it may be shorter. Hope it helps.

Complication!

There are risks associated with any surgery, and myopia eye laser surgery cannot completely avoid complications. The most common complication is overcorrection or undercorrection, which requires a certain period of observation and a second operation as appropriate; Some people may experience glare, that is, a spot of light is seen as a light cluster or halo at night, which can be related to the slight edema reaction between the corneal tissues after surgery or the large pupil at night, and its edge is close to the surgical margin, which gradually decreases with the passage of time after surgery; Keratoconus occurs in people who have this potential or who have a thin cornea after surgery; Eccentric cutting may occur due to poor fixation of the target, or the central island may occur due to the action of moisture vortex on the corneal surface; There may be corneal opacity (haze) after PRK and LASEK surgery and hormonal hypertonic intraocular pressure caused by long-term spot use of drugs that fight HAZE. Lasik has complications related to the corneal flap, such as subvalvular foreign body, corneal flap displacement, dissolution, increased astigmatism, and perceived dryness of the eyes.

The most serious is the infection of the corneal wound of the surgical eye, which is a direct cause of blindness, although rare, so a strict surgical sterilization regime and good patient hygiene habits are essential. After surgery, the eyes should also be examined regularly, paying special attention to the changes in the macular area and the surrounding retina under the eyes to take precautions.

If the cornea is involved, these symptoms can be caused, such as cataract surgery, glaucoma, pterygium surgery, etc., generally 3 months to half a year is still not good, with glasses.

Under normal bodily functions, glare occurs after surgery, which is a short-term complication of conventional surgery and is mitigated by postponement over time. However, in daily life, to avoid the damage of strong light to the eyes, it is generally necessary to wear sunglasses outdoors (with better UV protection). In this way, there will be no secondary trauma to the eye.

This is one of the common sequelae of myopia surgery, and it is recommended to go to the hospital for timely examination and follow the doctor's instructions.

This is one of the reasons why many doctors do not recommend myopia surgery, after all, the sequelae after surgery are very troublesome.

Therefore, if you don't want to have surgery in adulthood and don't want to wear glasses for a long time, it is best to find myopia in time**. Generally, doctors recommend timely oral oral eye vision nutrients, two sachets a day, and insist on taking it for a period of time, which can reduce the degree of myopia, improve vision, and avoid the trouble of surgery in adulthood.

After myopia eye surgery, since the corneal wound is not completely healed in a short period of time, it is still necessary to pay attention to reasonable eye habits and keep the eye part clean during this period. First of all, regular use of drugs is required to prevent the occurrence of local infections and reduce local inflammatory reactions. Commonly used drugs are mainly glucocorticoid eye drops, such as fluorometholone eye drops, which take about 2-3 weeks to use.

Clause. 2. It is necessary to go to the hospital regularly to review the changes in vision and check whether there are any complications. Clause.

3. During this period, we must pay attention to reasonable eye habits and avoid excessive eye use. If you always stay up late or use electronic products such as computers and mobile phones for too long during this period, it is not conducive to the recovery of the disease. In severe cases, it may even lead to complications such as dry eye syndrome and corneal infection, so be careful after surgery.

Glare after myopia eye surgery is common, and not only glare will occur, but also symptoms such as monocular diplopia, polyopia, and halo may occur. These conditions are mainly due to a normal optical reaction of the cornea during the healing period, generally about a month after the operation, the corneal wound is healed, and the symptoms gradually disappear, so there is no need to worry too much, you can follow up regularly. If this symptom does not resolve for a long time, it is considered that there may be a local complication, such as severe dry eye or infectious disease, interlaminar corneal debris, etc.

At this time, it is necessary to go to a regular hospital for a detailed physical examination, and then decide how to deal with it according to the examination situation. Therefore, if there is myopia in the eye, surgery can be considered**, and after the operation, you need to pay attention to reasonable eye habits to avoid excessive eye use, so that the disease can recover faster.

Chengdu myopia surgery expert Zhou Jirong: Why do some people have glare after surgery?

After refractive surgery, there will be a circular corner on the cornea (as shown below), and glare will occur when light enters the eye from this missing position and reaches the retina, which may be reduced to a certain extent, but will always be present. Some people say that the glare will lessen over time, but this is not true. It's just that after a long time, the recipient has mastered the technique of avoiding this directional light, and it is not easy for him to perceive this phenomenon.

It may be caused by excessive use of the eyes after the surgery, staying up late, or corneal edema. If it is indeed caused by corneal edema or poor repair, you can use eye masking potions to promote corneal recovery, as well as a small amount of hormones, such as Beifushu eye drops, plus fluorometholone eye drops. But for now, you must follow suit and take a break.

1. People with large pupil diameter are prone to postoperative glare: everyone's pupil size is different, and those with too large pupil diameter are still difficult to completely cover their pupils under dark light even if they use large light area cutting**, so it is best not to choose myopia correction surgery for such people (ICL is also not suitable).

2. Those with high myopia are prone to postoperative glare: the higher the myopia, the more cornea will be cut, the deeper the "depression" formed on the surface of the cornea, and the greater the slope.

3. The small light area of laser cutting can cause postoperative glare: the size of the light area of different brands of excimer laser equipment is not the same. Yes, etc., the transition zone can be increased to.

If the light area is small, glare symptoms occur when the pupil diameter exceeds the light area in low light. Wavefront aberration-guided individualized cutting technology** with aperturbation can significantly improve visual quality and significantly reduce the occurrence of glare and halo.

Therefore, people with high myopia, small laser cutting light area and large pupil diameter in low light are risk factors for poor night vision, glare and halo after surgery. Experts remind that the excimer laser surgery must be done in a regular ophthalmology hospital, and the surgery can be performed only after a rigorous preoperative examination is done to determine that the patient is suitable for excimer surgery to avoid the glare problem after laser myopia surgery.

There is a considerable number of people who undergo laser refractive surgery who have this phenomenon.
