How Long After Femtosecond Laser Surgery Can The Eye Be Functioning Properly

Generally speaking, myopia can be used normally 3-5 hours after eye surgery, and most patients can generally start to use their eyes normally on the first day after surgery, without delaying normal study, work and life. Patients with mild to moderate refractive errors have a recovery time of about two weeks after myopia eye surgery, when normal vision is basically restored. The recovery time after myopia eye surgery varies from person to person, but there are mainly three factors that determine the recovery time for myopia eye surgery:

1. The degree of myopia before myopia surgery is different, and the recovery time is also different. Generally, the power of both eyes before surgery also determines the speed of the postoperative recovery period. Then if it is a patient with high myopia above 600 degrees, the recovery time of myopic eye surgery must be longer than that of patients with moderate and low myopia.

2. The recovery time for myopia eye surgery varies from person to person. In most cases, people with good physical fitness will naturally recover faster, on the contrary, those with poor physical fitness will recover relatively slowly, but not too much.

3. The recovery time is of course different depending on the type of myopia eye surgery. At present, there are many types of myopia eye surgery, and the recovery time of each myopia eye surgery is different.

Hello, Dr. Aier warmly reminds that the general femtosecond laser surgery can be used normally after the second day of reexamination, within a month the eyes will be more sensitive, vision will fluctuate with your eye intensity, during this time you must pay attention to the intensity of your eyes, TV, computer, etc. can be less or less, the better the maintenance, the better the recovery. Visual acuity is basically stable after one month and completely stable after three months.

Everyone's post-operative symptoms are different, and the recovery time is different. It usually takes 1-3 months for your vision to stabilize after surgery.

Full recovery for more than a month after corneal laser surgery. Corneal laser surgery takes half a day to check, meet the conditions to make an appointment for surgery, myopia is irreversible, there is no effective drug **, there is no effective physical method**, just to correct myopia, glasses are the first choice, generally do not advocate corneal laser surgery, the above is Quanzhou Aier Eye Hospital to tell you, if there are any questions, it is recommended to go to the hospital for a detailed consultation.

Corneal damage from laser surgery of the eye generally recovers within 1 to 2 weeks, and full recovery takes about 1 to 3 months. During this period, it is necessary to take medication on time and pay attention to eye hygiene. Do not overuse your eyes for 1-3 months after surgery to avoid dry eyes.

Corneal reactive edema after laser surgery for myopia, whether anti-infective, anti-inflammatory drugs are used**. Generally, corneal edema can subside after 2 to 3 days, and the patient's vision is significantly improved. But for the eye to fully regain visual stability, it takes 1-3 months.

Therefore, it is advisable not to work too early, especially for patients who need to work on a computer for long periods of time.

I did a full femtosecond and it was back the next day, and I could see it clearly. Southeast, ophthalmology doctors say it takes three to six months to be fully stabilized.

Depending on the person's constitution, recovery after surgery may take a week to longer, and the recovery time varies from person to person.

The amount of cornea to be removed is determined based on the comprehensive data of the patient's eye examination, and the remaining safe corneal thickness must be greater than 410 microns. If you need femtosecond laser surgery, it is recommended to choose Beijing Meier Eye Hospital. Click to test if I am suitable for myopia surgery.

The corneal thickness of the cornea is about 12um per 100 degrees of full femtosecond incisation, and the remaining corneal thickness of 410 microns is retained after each patient's surgery. In laser surgery, for every 100 degrees of myopia corrected, it is necessary to cut to 12 microns of cornea, so the thickness of the single cornea can be laser surgery, and the degree of myopia that needs to be corrected is also very related, and the more corneal thickness is retained, the higher the success rate of the operation, in order to ensure the operation, the hospital will do a lot of preoperative examination on the patient before the operation, including visual acuity, refraction, corneal bean, corneal topography, anterior fundus examination, to determine whether the patient meets the conditions for surgery.

If you want to know more about a femtosecond laser surgery, we recommend consulting Beijing Meier Eye Hospital. Beijing Meier Eye Hospital is one of the hospitals under Meier Medical Group, a designated hospital of Beijing Medical Insurance and the teaching base of Peking University Health Science Center, and is a large-scale professional ophthalmology hospital. The hospital integrates medical treatment, teaching and scientific research, and has international advanced diagnosis and treatment equipment to provide patients with professional and high-quality medical services.

Basically, every 100 degrees of myopia requires the consumption of corneal thickness at 14um (microns). The hospital is a well-known ophthalmology hospital in China, with an annual outpatient volume of more than 10 million and more than 1 million surgeries in Chinese mainland, and a medical service network covering nearly 3 billion people around the world. Click to test whether I am suitable for myopia correction.

Laser surgery is divided into full femtosecond and half femtosecond, which is basically only suitable for people with about 300 degrees to 600 degrees, and many people with high myopia cannot do laser surgery, because the myopia degree is too high, and the corneal thickness may not be enough to cut the cornea if the myopia is more than 1,000 degrees. Femtosecond laser surgery basically consumes a corneal thickness of 14um (microns) per 100 degrees of myopia, while the thickness of the human cornea is different, the thinnest part, the thickness is, and the peripheral part can reach 1mm, so the thousand-degree myopia basically bids farewell to laser surgery.

In femtosecond laser surgery, 90-100 microns are generally incised to make a thin cornea, and 13 microns of cornea are consumed every 100 degrees when the excimer laser cuts the stromal layer.

For example, for 300-degree myopia, do a half-femtosecond excimer laser. The cornea was originally 500 microns, and the postoperative corneal thickness was 500-39 m = 461 m

The femtosecond laser directly penetrates and cuts the corneal stromal layer, consuming 15 m cornea for every 100 degrees of myopia.

Taking 300 degrees and a corneal thickness of 500 m as an example, the postoperative corneal thickness is 500-45=454 m.

It takes about two hours to do the pre-femtosecond laser myopia surgery, and after the examination confirms that the conditions for surgery are met, make an appointment with the doctor for surgery, and arrange the operation within 1-3 days; The operation lasted more than 10 minutes, and after the operation, I wore an eye patch with holes and went home to close my eyes and rest, and there was no need to be hospitalized. On the second day after surgery, I went to the hospital for a follow-up examination, and I was able to use my eyes normally after removing the blindfold.

From going to the operating table to getting off the operating table, 5-10 minutes. It usually takes 10-20 minutes to wash the eyes before surgery, dispense medicines, educate and postoperative slit lamp examination in the operating room.

The preoperative examination takes 2-3 hours, and the operation time is 10-20 minutes.

1. Pay attention to the time you spend with your eyes.

Children's eye development is not perfect, the ability to work is low, every time you read or write for an hour, you should let the child go to outdoor activities, do games, look into the distance, or observe the flowers and trees, so that the tense eye muscles are relaxed, eliminate fatigue. In addition, it is necessary to make the child's life regular, have enough sleep, and let the eyes get enough rest.

2. Pay attention to the light of your eyes.

Do not allow your child to read or write in dark light or sunlight. If a 25-watt light bulb is used indoors at night, the distance between the book and the bulb should be within 1 meter. If you use a 60-watt bulb on a stool, the distance between the book and the bulb should be 1 2 meters.

Cloudy days, dusk, weak light in the moonlight, and strong light in the sun are not suitable for reading and writing. When watching TV, it is necessary to maintain a suitable distance, which should generally be 5 7 times the diagonal length of the phosphor screen. The time to watch TV should not exceed 2 hours at a time.

3. Pay attention to eye exercise.

Physical exercise can enhance blood circulation and metabolism, supply more nutrients to the eyes, and enhance the resistance of the eyes, which is an indirect exercise for the eyes. The direct exercise is eye exercises, which is based on the massage, massage, acupuncture and acupuncture acupuncture points of Chinese medicine, combined with jujube Kuanhui medical sports, which is a scientific method to protect eyesight. Parents should learn the basic knowledge of eye exercises, give specific guidance and often urge their children to do eye exercises, and persevere.

4. Pay attention to eye nutrition.

In order to protect children's eyes, children can eat more carrots, animal liver, lean meat, to supplement vitamin A, or regularly supplement the comprehensive nutrition of the eyes with Leyan vision nutrients, and at the same time, it is also necessary to appropriately consume millet, tofu, animal liver and other supplements of vitamin B2, so as to avoid night blindness, corneal malacia, red eyes, dry itching and other symptoms. Eating too much sugar will harm your child's eyesight, so your child's sugar intake should be controlled.

5. Pay attention to regular inspections.

Regular check-ups are due to the fact that children's eye structure, binocular visual function, and intelligence are still in the process of continuous development after birth, and the content of the examination is different at different ages. The usual age of ophthalmologic examination is generally 2-7 days after birth, 42 days after birth, 3 months, 6 months, and 1 year of age, and then once a year. In this way, the problem can be detected early and corrected early, instead of waiting until the vision has deteriorated and there is a vision problem before going for a check-up.
