Wuhan Tongji Hospital femtosecond: how to carry out laser correction surgery?
Laser correction surgery is a common ophthalmic surgery, which is used to correct myopia, hyperopia, astigmatism and other vision problems. Tongji Hospital is one of the well-known ophthalmic hospitals in Wuhan. It has advanced technical equipment and professional medical team to provide patients with safe and accurate laser correction surgery. This article will elaborate on the laser correction surgery from four aspects: operation process, preoperative examination, postoperative nursing and effect evaluation.
Operation process
Laser correction surgery is mainly divided into two common methods: femtosecond laser keratectomy (FS-LASIK) and femtosecond laser epithelial keratectomy (FS-FLAP).
In FS-LASIK surgery, doctors first use a femtosecond laser to make a thin corneal flap, then fold the flap like tissue, and then use the laser to remove the tissue in the inner layer of the cornea, and finally restore the flap like tissue. The whole process is fast and accurate.
In the FS-FLAP operation, the doctor uses a femtosecond laser to make a thin upper flap, then uses the laser to remove the tissue under the epithelium, and finally restores the upper flap. Compared with FS-LASIK, the thickness of cornea cut by FS-FLAP is relatively thin, which is suitable for patients with thin cornea.
Both of the two surgical methods can effectively change the corneal curvature, so as to achieve the purpose of correcting vision problems.
Preoperative examination
Before the laser correction surgery, the professional doctors of Tongji Hospital will conduct a comprehensive preoperative examination for the patients. These examinations include fundus examination, corneal topography, wavefront examination, etc. Through these examinations, doctors can understand the patient's eye conditions and judge whether it is suitable for laser correction surgery.
The preoperative examination also includes the patient's medical history, such as whether there is eye disease, surgical history, and the use of ophthalmic drugs. This information will help doctors evaluate and plan surgery more accurately.
Postoperative care
After laser correction surgery, the medical team of Tongji Hospital will give detailed postoperative nursing guidance to patients. Patients need to pay attention to protecting their eyes, avoiding strenuous exercise, excessive eye use, etc. The doctor will also give the patient advice on eyedrops and drug use to promote corneal healing and reduce discomfort.
The recovery period after surgery may be different for different patients, but most patients can feel significant visual improvement within a few days after surgery. At this time, we need to follow the doctor's guidance to return regularly to ensure stable vision.
Effect evaluation
The evaluation of the effect of laser correction surgery is a long-term process. Tongji Hospital will require patients to come back regularly after surgery to assess their vision and corneal condition through fundus examination, corneal topography and other methods.
According to the evaluation results, doctors can adjust the treatment plan of patients to achieve the best correction effect. Some patients may need a second operation to further improve their vision.
In general, the laser correction surgery in Wuhan Tongji Hospital is a safe and accurate method to treat myopia, hyperopia and astigmatism. Through the detailed description of the operation process, preoperative examination, postoperative nursing and effect evaluation, we hope to help patients understand and choose their own correction methods.
