Examination before myopic surgery
Before myopic surgery, patients need to undergo a series of ophthalmic examinations to determine the indications and operation plan of the surgery. First, the doctor will perform a vision examination to determine the degree of myopia and corneal curvature of the patient. Then, the doctor will perform fundus examination to determine whether there are other eye diseases or abnormalities. Next, the doctor will perform a diopter test to determine the refractive adjustment parameters for the surgery. Finally, the doctor will conduct tear analysis and corneal topography examination to assess the health of the cornea and the feasibility of surgery.
When performing these examinations, patients need to pay attention to the following matters. First, patients need to stop wearing contact lenses in advance, usually for more than two weeks. Contact lenses can change the shape of the cornea, which may affect the surgical results. Secondly, patients need to maintain good eye hygiene and avoid using eye drops and cosmetics containing irritants. Finally, the patient needs to cooperate with the doctor for examination. For example, during fundus examination, the patient needs to cooperate with the doctor to look at a certain point to ensure the accuracy of the examination results.
To sum up, the examination before myopia surgery is an important step to ensure the safety and effect of surgery, and patients need to cooperate with doctors to carry out relevant examinations and preparations.
Preoperative preparation for myopia surgery
Before myopia surgery, patients need to make some preoperative preparations to ensure the safety and smooth operation. First, patients need to stop using drugs that may affect the operation in advance, such as anticoagulants, immunosuppressants, etc. These drugs may increase the risk of bleeding or interfere with postoperative recovery. Secondly, patients need to comply with the requirements of fasting and water deprivation before surgery to ensure that the stomach is empty during surgery and reduce the risk of surgery. In addition, the patient also needs to arrange the rest and recovery after the operation in advance to avoid overwork or external stimulation.
In addition to the above preoperative preparation, myopic surgery also requires patients to understand the relevant information and risks of surgery. Patients need to fully communicate with doctors to understand the principle and process of surgery and possible complications after surgery. Only by fully understanding and making psychological preparation can patients better cope with the recovery and effect evaluation after surgery.
To sum up, the preoperative preparations for myopia surgery include drug withdrawal, fasting and water deprivation, and rest arrangements, and patients are required to fully understand the risks and effects of surgery.
Surgical selection for myopia
In myopic surgery, the common surgical methods include laser corneal refractive surgery (LASIK), surface covering surgery (PRK), and laser subepithelial plasty (LASEK). These surgical methods can effectively correct myopia, but the indications and surgical principles are slightly different.
LASIK surgery is suitable for patients with high myopia. It creates a pulling corneal flap in the middle of the cornea, and then corrects the cornea with laser. PRK surgery is suitable for patients with low myopia. It removes the epithelial layer of the corneal surface, and then corrects the cornea with laser. LASEK is a combination of LASIK and PRK, which is suitable for patients with special conditions.
When selecting the surgical method, the doctor will make a comprehensive assessment based on the patient's myopia, corneal curvature, eye size and other factors, and fully communicate with the patient to determine the most appropriate surgical plan.
Postoperative nursing of myopia surgery
Postoperative care is very important, which can help patients better recover their vision and alleviate discomfort. After surgery, patients need to follow the doctor's advice and do a good job in the following aspects of nursing.
First, the patient needs to pay attention to rest and avoid excessive eye use. It takes a certain time for vision recovery after surgery, and patients need to take a rest at the right time to avoid long-term eye use and reduce fatigue. Secondly, patients need to use antibiotic eyedrops and anti-inflammatory eyedrops regularly to prevent infection and alleviate eye discomfort. At the same time, patients need to avoid rubbing eyes, wiping eyes or wearing glasses, so as not to stimulate the cornea and affect the surgical effect. Finally, the patient needs to be reexamined according to the doctor's requirements to timely evaluate the surgical effect and deal with postoperative complications.
To sum up, postoperative care for myopia surgery includes rest eyes, eye drops and reexamination, which can help patients better recover their vision.
Summary
Myopic surgery is a common refractive surgery, which can effectively improve the vision of myopic patients. When performing myopia surgery, patients need to pay attention to the examination and preparation before surgery, including eye examination, drug withdrawal, fasting and water deprivation. When selecting surgery, doctors will choose the most suitable surgical method according to the patient's situation and needs. Postoperative nursing is the key to the success of the operation. Patients need to pay attention to rest, eye drops, and regular reexamination. Only by doing these things well, patients can better restore their vision and enjoy the convenience of having no glasses in life.
