Problems needing attention in myopia surgery
Myopic surgery is one of the common methods to treat myopia, which can greatly improve the vision of patients. However, before myopia surgery, patients need to pay attention to the following issues to ensure the safety and effect of surgery.
Ophthalmic examination
Before considering myopic surgery, patients need to undergo a comprehensive ophthalmic examination to determine whether surgery is appropriate. These examinations include measurement of intraocular pressure, corneal thickness and corneal topography. Only when the eye condition is good and there are no other potential eye diseases, the doctor will recommend the operation.
In addition, patients also need to take diopter measurements to determine the degree of myopia and the accurate measurement of eye length. These predictors will help doctors determine the appropriate procedure for surgery to obtain the best corrective results.
When performing ophthalmic examinations, patients should truthfully inform doctors of their own health and medical history, so that doctors can comprehensively assess the risks and effects of surgery.
Surgical selection
There are many methods for myopia surgery, including laser correction (LASIK) and corneal circumcision (PRK). The patient needs to fully communicate with the doctor to understand the advantages and disadvantages of various surgical methods and indications, so as to select a suitable surgical method.
For example, LASIK surgery is suitable for most myopia patients. It removes the tissue on the corneal surface through laser, thus changing the shape of the cornea and correcting vision. PRK surgery is suitable for patients with insufficient corneal thickness. It directly applies laser to the corneal surface. Each kind of operation has its own characteristics and risks, and patients need to choose appropriate surgical methods according to their personal conditions.
In the choice of surgery, the doctor's advice is crucial. Patients should carefully listen to the doctor's explanation and advice and make wise decisions.
Surgical risks and complications
Although the technique of myopia surgery is very mature, there are still some risks and complications. Patients need to fully understand the risks of surgery, including infection, dry eyes, vision changes and other possible problems.
Myopia surgery needs to be performed on the cornea, so patients may be at risk of corneal infection. In order to prevent infection, patients need to strictly follow the doctor's postoperative nursing guidance, such as using eye disinfectant, avoiding eye rubbing, etc.
In addition, dry eye symptoms may occur after surgery, including dry eyes, pain and blurred vision. Patients should actively follow the doctor's recommendations for eye moisturizing and lubrication to reduce the discomfort of dry eyes.
During the operation, some complications, such as corneal epithelial displacement and corneal scar, may occur, which requires comprehensive evaluation and treatment by doctors. Patients should have a clear understanding and receive necessary preoperative and postoperative examinations and treatment.
Postoperative precautions
After myopic surgery, patients need to pay close attention to the recovery of the eye and follow the doctor's postoperative guidance. This includes avoiding strenuous exercise, lifting heavy objects, rubbing or squeezing eyes, etc.
During postoperative recovery, the vision may have temporary fluctuations, which is normal. Patients can help their eyes recover and reduce discomfort by regularly using auxiliary devices such as eye drops and eye masks after surgery.
In addition, patients should be reviewed regularly after surgery to ensure the effect of surgery and assess the stability of vision. The doctor will evaluate the effect of the operation according to the review results and provide further suggestions and treatment.
Summary
Myopic surgery is an effective means to correct myopia, but before choosing surgery, patients need to have a comprehensive ophthalmic examination and fully communicate with doctors. The choice of surgery, postoperative risks and complications, and postoperative nursing care are the key issues for myopia surgery. By following the doctor's guidance and postoperative care, patients can obtain good surgical results and change the inconvenience caused by vision problems.
