How long does full femtosecond surgery take?
All femtosecond laser surgery is a modern advanced corneal refractive surgery, which is widely used in the correction of myopia, hyperopia and other eye diseases. This kind of operation is welcomed by patients because of its accuracy, rapidity and rapid recovery. So, how long does the full femtosecond surgery take? The time of full femtosecond surgery is described in detail from four aspects below.
Preparation of operation time
Before going to the hospital for full femtosecond surgery, a series of examinations and preoperative preparations are required. The patient first needs to have an eye examination to assess the health of the eye and determine whether it is suitable for surgery. In addition, relevant preoperative tests, such as fundus photography and visual inspection, are also required to ensure the safety and accuracy of the operation. Usually, this process may take about 1-2 hours.
After discussing with the doctor and determining the operation plan, the patient needs to wait for the hospital to arrange the operation time, which usually takes several days to several weeks, depending on the hospital's arrangement. During this period, patients need to pay attention to maintaining eye hygiene and avoiding the use of contact lenses.
Actual operation time
Once arriving at the operating day, the patient will undergo eye disinfection before surgery, and then enter the operating room. When receiving full femtosecond surgery, the doctor will give the patient some anesthetic eyedrops to ensure that the patient feels comfortable during the surgery. Usually, the operation takes only a few minutes.
During the operation, the patient will be asked to stare at the surgical instrument. The doctor will use the laser to form a very thin corneal flap on the corneal surface, and then gently open it. Next, doctors use laser instruments to adjust the lower cornea to eliminate vision problems. This process is very precise and controlled by computer. There is no need to use a scalpel and suture during the whole operation. After the operation, the doctor will wear protective goggles for patients to reduce discomfort.
Recovery time after operation
In general, the recovery time after full femtosecond surgery is relatively short. The patient needs to rest in the recovery room for a period of time, waiting for the anesthetic effect of the eyes to disappear. Later, the patient will receive a post-operative examination to confirm the effect of the operation, and obtain relevant precautions and suggestions for the use of eye drops. The whole postoperative procedure may take about 1-2 hours.
After returning home, the patient needs to continue eye care and use eye drops as recommended by the doctor to promote healing and reduce discomfort. Usually, patients can feel obvious improvement within a few hours after the operation, and basically return to normal life in about a week.
Summary
To sum up, the time of full femtosecond surgery mainly includes the preparation of the operation time, the actual operation time and the recovery time after the operation. Preparation before surgery includes ophthalmic examination and preoperative detection, which may take about 1-2 hours. The operation itself only takes a few minutes, but the patient needs to wait in the operating room for some time. The postoperative recovery time is relatively short, about 1-2 hours, and it basically returns to normal life in about a week. The speed and accuracy of full femtosecond surgery bring convenience and comfort to patients.
