Summer has been the peak season for laser myopia surgery for many years. This year is no exception. Recently, our hospital has received many calls for consultation, and many families ask if they can have surgery on the same day of the examination, after the preoperative examination. Insufficient time for preoperative medication ordering may risk infection According to the national standard for myopia surgery, in order to avoid intraoperative infection caused by bacteria on the eye surface, patients are required to order medication for 1~3 days before surgery, if the time or number of medication ordering is not enough, there may be a risk of infection, and the amount of medication used on the same day of surgery will definitely not reach the prescribed amount. The eye is hyperactive after the preoperative examination and needs to be rested to its natural state During the examination, test strips, pupil diluting drugs and other medications are needed, as well as a variety of examination equipment will come into contact with the eye, and the eye surface is in a hyperactive state after the examination is stimulated, which is not suitable for surgery at this time, and requires at least one night’s rest to return to its natural state. At the same time, Zen Eye requires each patient to eat a light diet the day before surgery, pay attention to rest, and try to ensure that the next day is in the best mental and physical condition. Pre-operative exams require dilated pupils, which can lead to inaccurate data. It takes 6 to 8 hours for the eye to return to its natural state after dilatation, so normal surgery cannot be performed on the same day. If you use pupil reduction medication to force the pupil to shrink in order to hurry, this may cause the pupil state to deviate from the actual state after medication, affecting the accuracy of the surgery. Tip: Eager parents, there is a scientific and standardized process for myopia surgery that aims to make each surgery safe and effective, giving everyone better visual quality and quality of life!
