What does myopia notice before and after operation? I’ll explain it to you once

Abstract: in the process of examination, what patients need to do is to cooperate well with doctors. For example, keep your eyes open and still during the examination. Full cooperation can ensure the rapid completion of the examination and the accuracy of the results. With the popularity of electronic products, the incidence rate of myopia in the world has been increasing. The incidence of myopia in China is increasing. Especially in the young people, the incidence rate of

is increasing year by year.

myopia is not a disease in essence (except pathological high myopia), but it will have varying degrees of impact on people’s work and life.

in recent years, the rapid development of corneal refractive surgery in China, especially the extensive development of femtosecond laser surgery, has further improved the safety of myopia surgery.

People all advocate high-quality life. Whether based on professional requirements or their own needs, people’s desire to remove glasses through myopia surgery is becoming stronger and stronger.

what should we pay attention to before and after myopia surgery

we should first talk about those things of preoperative examination. The preoperative examinations of


included naked visual acuity, best corrected visual acuity, optometry, corneal topography, ocular axis, corneal thickness, ocular surface and fundus. The results of preoperative examination will directly determine whether myopia surgery can be performed.

before preoperative examination, It should be done:

stop wearing soft contact lenses (contact lenses) for 1 ~ 2 weeks, hard contact lenses for 3 ~ 4 weeks and OK lenses for 3 months;

exclude acute eye lesions, such as acute conjunctivitis, keratitis, iridocyclitis, undiagnosed high intraocular pressure, uncontrolled glaucoma and fundus lesions;

In order to accurately determine the refractive state, rapid cycloplegic optometry is necessary, and fundus examination with dilated pupils is also very necessary.


during the examination, what the patient needs to do is to cooperate well with the doctor. For example, keep your eyes open and still during the examination. Full cooperation can ensure the rapid completion of the examination and the accuracy of the results. After the preoperative examination of


, it is necessary to communicate well with doctors and make corresponding preparations.


then, what should we communicate and do?

first, everyone’s development is different, Therefore, everyone’s ultimate vision (i.e. the best corrected vision that can be achieved) is different. Before operation, we must communicate with the doctor in time to fully understand our own situation, so as not to cause a large psychological gap after operation due to too high expectation;

Second, the choice of operation mode must be made after full communication with the doctor in combination with the preoperative examination results and their own situation. The operation mode varies from person to person. No operation mode can be suitable for everyone. Safety is the first principle, and the one suitable for themselves is the best;

third, during the preoperative conversation, we should listen carefully as much as possible, fully understand the risks of the operation, the possible situations during and after the operation, and sign the operation consent after it is clear;

fourth, the preoperative medication must strictly comply with the doctor’s advice, that is, drop antibiotic eye drops for a sufficient number of days and times before the operation. If the number of days or times are missed for various reasons, the operation is not allowed, because it may cause postoperative infection. Although it is very rare, once it occurs, it may cause irreparable consequences;


fifth, should ensure adequate sleep on the day before the operation. No cosmetic or perfume should be used around the eyes on the day of operation, so as to avoid the difficulty of cleaning and disinfection before operation, interfere with the operation and affect the operation effect.

sixth, preoperative adjustment of mental state, modern corneal refractive surgery mostly entered the whole laser era of knife, the operation process basically no pain.

because eye drops of surface anesthetics are used during the operation, there is generally no discomfort during and after the operation. When the anesthetic effect subsides, Discomfort can occur for a short time (usually relieved after 2 ~ 3 hours), including eye soreness, dryness, pain, tears, photophobia, etc.

The postoperative visual acuity recovery varies with different surgical methods and individual recovery ability. Most people can recover to normal visual acuity on the first day after operation, and some people recover slightly slower, which is a normal phenomenon. The stable period of postoperative visual acuity is generally 1 ~ 3 months. After


, eye drops should be dropped and rechecked regularly on time. Regular reexamination can timely understand the situation of postoperative recovery, and doctors can also deal with possible problems in time. Avoid rubbing the eyes after operation, avoid strenuous exercise within one week after operation, and suspend swimming within one month after operation to prevent dirty water from entering the eyes and avoid external force impact on the eyes. At the same time, the time and intensity of eye use should be properly arranged after operation, so that the eyes can get full rest.

when many friends think of myopia surgery, they are most concerned about postoperative complications. Of course, any surgery has risks, and myopia surgery is no exception. Over correction and insufficient correction are the most common. With the rapid development of technology and the accumulation of clinical experience, the incidence and deviation range of this situation have been greatly reduced. In very few cases, secondary surgery can be carried out as appropriate. In the early postoperative period of


, a few people may have glare, i.e. aperture and light mass at night vision point. On the one hand, the optical area of preoperative surgical scheme design refers to the pupil diameter under dark light, which can generally avoid the occurrence of glare; On the other hand, with the passage of time, postoperative glare can also be gradually reduced.

in addition, some people are prone to eye fatigue and mild dry eye discomfort in early postoperative close reading, which will be gradually relieved over time.

in short, corneal refractive surgery through standardized and strict preoperative examination, good intraoperative cooperation and postoperative care, and pay attention to eye hygiene, the risk is controllable, which can achieve the purpose of removing glasses and give you an unrestrained and clear world.
