How to correct myopia with laser in Shanghai Eye Hospital
Shanghai Eye Hospital is a hospital specializing in ophthalmic diagnosis and treatment. It has advanced equipment and technology to provide high-quality ophthalmic medical services for patients. Among them, laser myopia correction technology is an important technology in the hospital, which is favored by the majority of myopia patients. This article will elaborate the laser myopia correction technology in Shanghai Eye Hospital from four aspects: preoperative preparation, surgical process, postoperative nursing and effect evaluation.
Preoperative preparation
Before laser myopia correction surgery, patients need to make comprehensive preoperative preparation. First, the doctor will conduct a comprehensive examination of the patient's eyes to determine whether it is suitable for laser myopia correction surgery. Secondly, the doctor will explain the principle, risks and precautions of the operation to the patient in detail, and sign the informed consent form with the patient. The preoperative preparation also includes stopping wearing contact lenses for a period of time to ensure the stability of the cornea.
Next, doctors will develop personalized surgery plans based on the patient's eye data. The operation plan needs to consider the patient's corneal curvature, degree, corneal thickness and other factors to ensure the accuracy and safety of the operation effect. Before operation, the patient should also pay attention to the adjustment of diet and life rules to ensure the smooth operation.
The importance of preoperative preparation cannot be ignored, which has laid a solid foundation for the success of surgery and the safety of patients.
Operation process
Laser myopia correction surgery is usually divided into two stages: corneal ablation and corneal remodeling. Before the operation, the doctor will give local anesthetic eyedrops to reduce the patient's discomfort.
First, doctors will use a laser knife to leave thin "flaps" on the corneal surface, a process called corneal ablation. Then, doctors use lasers to reshape the cornea to correct myopia. Laser reshaping can accurately eliminate the refractive error of the anterior surface of the eye according to the patient's corneal data and surgical plan.
The whole operation process usually takes only a few minutes. The doctor will monitor the condition of the eyeball in real time to ensure the accuracy and safety of the operation. After the operation, the doctor will give the patient relevant postoperative nursing knowledge and drugs to help the patient recover quickly.
Postoperative care
Postoperative nursing is an important part of laser myopia correction surgery. Patients need to follow the doctor's instructions and use relevant eyedrops and antibiotic ointment on time to alleviate eye discomfort and prevent infection.
After surgery, patients need to pay attention to avoiding strenuous exercise, excessive eye use and eye protection. At the same time, avoid contact with water and do not rub eyes to prevent corneal flap displacement or infection. Within a few days after the operation, the patient may feel blurred vision or slight discomfort, which is a normal recovery process. The patient should be patient.
Regular follow-up is also an important part of postoperative nursing. The doctor will perform eye examination on the patient, evaluate the surgical effect, and give further guidance and suggestions.
Effect evaluation
The evaluation of the effect of laser myopia correction surgery needs to be carried out in a period of time after the surgery, because the eyes need a certain time to recover and stabilize. Generally speaking, the vision of patients after surgery will be significantly improved, and they will no longer rely on glasses or contact lenses. Patients can perform visual inspection and diopter test to verify the effect of surgery.
However, laser myopia correction surgery also has certain risks and limitations, such as xerophthalmia, infection, vision regression and other problems after surgery. Therefore, for the evaluation of postoperative effects, doctors will focus on such factors as vision correction, the incidence of surgery related complications and patient satisfaction.
In general, the laser myopia correction technology in Shanghai Eye Hospital is an eye surgery with strict preparation and accurate operation. Scientific guidance and careful attention have been paid to preoperative preparation, operation process, postoperative nursing and effect evaluation. Patients can obtain obvious vision improvement and improve quality of life through this technology.
