1、 Ophthalmic examination

Before femtosecond laser surgery, patients need to undergo a series of eye examinations. The first is visual inspection. By measuring naked vision and correcting vision, doctors can know the degree of myopia and astigmatism of patients, so as to determine whether it is suitable for laser surgery. The second is corneal topography, which can measure the curvature and shape of the cornea and evaluate whether the cornea is flat or steep. At the same time, it is also necessary to measure the axial length of the eye, which is to understand the length of the patient's eyes to determine the treatment parameters required for surgery. Tear analysis is also required to determine if the patient has a dry eye problem.

In addition, fundus examination is also required before femtosecond surgery to exclude any possible fundus lesions in patients* After that, the doctor will also conduct a comprehensive ophthalmic examination, including intraocular pressure measurement, corneal thickness measurement and eye movement examination. Through these examinations, doctors can assess the patient's eye health and make full preparations for the operation.

2、 Preoperative preparation

Before femtosecond surgery, patients need to do some preoperative preparations. First, patients need to stop using contact lenses, usually some time in advance, to ensure that the shape and terrain of the cornea return to normal. In addition, patients also need to stop using eyedrops, especially eyedrops containing corneal shaping lens components, to avoid affecting the surgery.

On the day before the operation, the patient needs to have a full rest to ensure a good physical and mental state. At the same time, patients also need to follow the doctor's dietary guidance to avoid excessive intake of caffeine, alcohol and other stimulants. In addition, patients should avoid wearing any jewelry and cosmetics on the day of operation to avoid interference with the operation.

In addition, femtosecond surgery usually requires the use of local anesthesia. Patients need to know in advance about the possible discomfort symptoms during the surgery and tell the doctor about their physical conditions so that the doctor can reasonably adjust the amount of anesthetic.

3、 Operation arrangement

Before femtosecond surgery, patients need to make surgical arrangements with the hospital in advance. First of all, the patient needs to go to the hospital in person for preliminary assessment and consultation, and the doctor will develop an appropriate surgical plan according to the patient's eye conditions. Then, the patient needs to make an appointment for the operation time and pay the corresponding operation fee.

On the day of operation, the patient needs to arrive at the hospital in advance to prepare for the operation. The doctor will reassess the patient's eye condition and explain the operation process and precautions to the patient. Patients need to sign an informed consent form to ensure that they have fully understood the risks and effects of surgery. After that, the patient will be guided into the operating room to start femtosecond laser surgery.

After the operation, the patient needs to rest for a while, and the doctor will conduct postoperative inspection and guidance to inform the patient of postoperative precautions and nursing methods. Patients can choose to stay in hospital for one night observation to ensure a smooth recovery after surgery.

4、 Postoperative recovery

Femtosecond surgery is a minimally invasive surgery, and patients can usually recover quickly after surgery. However, patients still need to follow the doctor's postoperative care guidance to promote corneal healing and recovery.

First of all, patients need to avoid intense eye activities, such as eye wiping, eye rubbing, etc. At the same time, patients need to use postoperative eyedrops on time to prevent eye infection and reduce eye discomfort. For a period of time after surgery, the patient also needs to avoid strenuous exercise to prevent the eyes from being collided and rubbed.

Within a few days after the operation, the patient needs to be rechecked as required by the doctor to ensure the healing of the eyes. The doctor will timely adjust the dosage of eye drops after surgery according to the specific situation of the patient, and guide the patient to carry out vision recovery training.

In a word, before femtosecond surgery, some eye examinations should be carried out, preoperative preparations should be made, surgery arrangements should be made with the hospital, and postoperative recovery care should be done. Through these steps, patients can be relieved to perform femtosecond laser surgery, reduce the problems caused by myopia and other eye problems, and restore clear vision.
