Can myopia surgery be performed on the same day as the examination?

In order to ensure the safety and effectiveness of myopia surgery, detailed preoperative examinations and preoperative medication and other preliminary preparations are required before the operation. Surgery can only be performed after strict evaluation by the doctor. It is not possible to perform surgery on the same day of examination.

1. Preoperative medication

The country has strict standards for myopia surgery. In order to prevent postoperative infection, all refractive surgeries require preventive antibiotic eye drops before surgery. Patients are required to apply antibiotics 1-3 days before surgery. The purpose of this is to sterilize the conjunctival sac as much as possible before surgery to avoid secondary infection after surgery. If the number of preoperative medications is not enough, the chance of postoperative infection will increase. Therefore, it is not recommended to perform surgery on the same day of examination.

2. Preoperative examination

Refractive surgery may seem simple, but the preoperative examination takes a long time, about two hours. Among them, the mydriasis examination is very important. By paralyzing the ciliary muscle, the patient's refractive state can be understood as accurately as possible, which is very important for the design of the next surgical plan and the implementation of the operation. After mydriasis, it takes 6-8 hours for the eyes to return to their natural state. If the surgery is performed with mydriasis, it may result in inaccurate correction.

The purpose of preoperative examination is to confirm whether surgery is possible and exclude potential contraindications such as keratoconus, severe dry eyes and thin cornea. Then, accurate surgical data should be provided, such as corneal curvature, degree, astigmatism axis, corneal topography, etc. Furthermore, professional preoperative examination can also screen other eye diseases, especially fundus diseases, such as fundus hemorrhage, retinal tears and detachment. A complete and strict preoperative examination is the premise to ensure the safety and effectiveness of surgery.

3. Preoperative gaze training

The success of a myopia surgery depends not only on the personalized surgical plan design, surgeons and surgical equipment, but also on the close cooperation of the patient. Close cooperation during the operation is inseparable from good preoperative gaze training. Of course, there is no need to worry. Preoperative gaze training only requires fixed gaze for 30-60 seconds without closing the eyes or blinking, which can basically meet the requirements of intraoperative cooperation.

Zhao Bo, director of Tianjin University Aier Eye Hospital, said that it is not recommended to perform myopia surgery on the same day of examination. Patients who need myopia surgery should arrange time for examination in advance and leave ample time for surgery preparation. Generally speaking, myopia surgery requires 3 days of preparation, one day for examination, one day for surgery, and one day for follow-up examination.
