Problems with night ghosting after femtosecond lasers

First of all, all myopia surgeries will cause glare for a period of time after surgery, whether you use a femtosecond laser with good postoperative results, especially a da Vinci femtosecond laser, or a lamellar knife with a less effective postoperative effect. After 6 months, the glare is almost gone. Recommendations:

After 3 months, you will go to the hospital for observation, and if there is still a little glare, you will go to the hospital for a check-up in 6 months.

Femtosecond laser myopia surgery is mainly different from conventional excimer laser surgery with mechanical lamellar knife in that the corneal flap is made.

Femtosecond laser myopia surgery uses a laser to make a corneal flap without a blade, while conventional excimer laser surgery uses a mechanical corneal lamellar knife to make a corneal flap, and the excimer laser cutting after the corneal flap is made is the same.

Femtosecond laser myopia surgery can produce a corneal flap with a very precise thickness and a smoother surface, and there is almost no displacement, displacement, or fragmentation of the corneal flap.

Therefore, the use of femtosecond laser to make corneal flaps can greatly improve the safety of excimer laser surgery**myopia, especially for myopia surgery patients with thin cornea and large variation in corneal curvature.

In general, the occurrence of glare and ghosting after myopia surgery is not only related to the corneal flap, but also related to the smoothness of the corneal cutting surface of the excimer laser, the size of the higher-order wavefront aberration after surgery, and the size of the pupil.

Due to the smoother corneal flap, femtosecond laser myopia surgery can reduce the phenomenon of glare and ghosting after surgery.

Glare is a sequelae of most people after refractive surgery, which is caused by the triangular prism effect of slight folding of the edge of the cut part and the uncut part of the surgery. It is difficult to completely eliminate the relief, and the only way to reduce or disappear is by selecting the angle at which the light enters the eye. Looking at the words, there is double vision, one may be that there is slight edema at the surgical site, and the other may be that there is a certain degree of astigmatism at present, and you can understand what is going on with a refraction.

Sometimes you can see clearly, sometimes you can't see clearly", it may be that the correction is slightly excessive (this is the most common surgical option), the eye will be able to see clearly when the adjustment is in place, and it will be unclear if the adjustment is not in place, because although the surgery changes the refraction of the cornea, it cannot change the physiological adjustment ability of the myopic eye itself.

Now that you have undergone refractive surgery, you can only wait for recovery and change, and there is no point in worrying.

You can use your eyes normally on the second day after femtosecond surgery, and it will not affect your normal life. Wash your face three days after femtosecond surgery, you can use facial cleanser and makeup for a week, and you can apply eye makeup after one month. You can swim for three months.

Adults who have already reached adulthood may consider myopia correction surgery to improve their vision.

Myopia laser surgery is generally more than 10,000 yuan, myopia surgery is divided into 2 categories, laser and lens implantation, and lens implantation surgery is generally 2-30,000 yuan.

According to your actual situation, you can choose a specialized hospital for myopia surgery, you can consult on the official website or **.
