Wuhan Tongji Hospital femtosecond laser surgery

Femtosecond laser surgery is one of the advanced ophthalmic surgery technologies. Wuhan Tongji Hospital, as a professional eye treatment hospital, is also a pioneer in providing femtosecond laser surgery. So, what is femtosecond laser surgery? The following is a detailed introduction from four aspects: preoperative preparation, operation principle, operation process and postoperative nursing.

Preoperative preparation

Before femtosecond laser surgery, the hospital will arrange a professional ophthalmologist to conduct a comprehensive eye examination. These examinations include fundus examination, optometry and corneal topography. According to the examination results, the doctor will develop a personalized operation plan for the patient and inform him of the operation precautions.

Before surgery, the patient needs to stop using contact lenses for a period of time to reduce its impact on the cornea. In addition, patients need to follow the doctor's instructions for necessary eye cleaning, and avoid the use of cosmetics and accidental eye injuries.

Operation principle

Femtosecond laser surgery is to adjust the curvature of the cornea by accurately controlling the high energy pulse generated by the laser on the cornea to make the corneal tissue damage and remove the micron level damage, so as to achieve the purpose of correcting myopia, hyperopia and astigmatism. Compared with traditional surgical methods, femtosecond laser surgery is more accurate, safe, and fast recovery.

During the operation, the doctor uses a laser device to focus the laser energy on the corneal tissue, remove the required corneal thickness, and then change the refraction of light by changing the shape of the cornea to improve the vision of the eye.

Operation process

The whole process of femtosecond laser surgery usually takes only a few minutes. First, the doctor will give the patient some anesthetic eyedrops to alleviate the discomfort during the operation. Then, the doctor will place a device to keep the patient's eyes open and aim the laser device at the cornea.

Next, the doctor will start the laser, control the laser energy and time, and accurately remove corneal tissue. During the whole process, the patient may feel a little pressure or slight eye discomfort, but it is not painful.

After the operation, the doctor will give the patient eye drops, and then the patient can rest for a while and carry out postoperative care under the guidance of the doctor.

Postoperative care

Within a few days after the operation, the patient needs to follow the doctor's instructions for eye care. The doctor will prescribe appropriate eyedrops and ointment to the patient, and inform them of the use methods and precautions.

During the recovery period, the patient should avoid strenuous exercise and eye collision by external force, and pay attention to eye cleaning. Doctors usually arrange patients to have regular re examinations to ensure the effect of surgery and eye health.

Summary

Femtosecond laser surgery is one of the advanced ophthalmic surgery technologies provided by Wuhan Tongji Hospital. Preoperative preparation includes eye examination and cleaning. The principle of surgery is to improve vision by controlling the laser to generate high-energy pulses on the cornea. The operation process is simple, and postoperative care needs to follow the doctor's guidance. Femtosecond laser surgery solves the eye vision problem for patients and improves the quality of life.
