Risk 1: Complications during operation
Any operation has certain risks, and myopia surgery is no exception. Common surgical complications include infection, corneal ulcer, elevated intraocular pressure, etc. Keratitis may be caused during the operation, leading to eye infection. If the infection is serious, it may also affect the recovery process and even lead to blindness. In addition, the intraocular pressure may rise during the operation. If the intraocular pressure is too high for too long, it will also cause serious damage to the eyes.
In addition to the above common complications, there are also some rare but serious complications, such as retinal detachment, corneal perforation, etc. These complications may cause permanent damage to the patient's vision and eye health, so it is necessary to fully understand these risks before surgery and have a detailed discussion with the doctor.
The risk of complications during surgery exists, but this does not mean that every patient undergoing surgery will have complications. The doctor will conduct a comprehensive assessment before the operation to ensure that the operation is suitable for the patient, and take corresponding preventive measures to reduce the risk of complications.
Risk 2: vision problems after surgery
The purpose of myopia surgery is to correct vision, but sometimes some vision problems may occur after surgery. The most common problem is unstable vision after surgery. In the days or weeks after the operation, the vision may fluctuate, sometimes even worse than before the operation. This is mainly caused by the adjustment and recovery of corneal tissue during surgery, which usually gradually stabilizes within a few weeks.
In addition to unstable vision, vision loss, visual quality degradation, light interference and other problems may occur after surgery. These problems can usually be improved through the follow-up observation and adjustment of doctors after surgery, but there are still a few patients who may not be able to fully recover to the vision level before surgery.
Before the operation, be sure to discuss the possible vision problems after the operation in detail with the doctor, understand the possible impact and treatment methods, so as to make a wise decision.
Risk 3: corneal refractive instability
Myopic surgery is mainly to correct vision by changing the shape of the cornea, so it may lead to corneal refractive instability after surgery. The corneal refractive instability will lead to the rebound of vision, that is, the vision will improve briefly after surgery, but then the vision may return to the level before surgery again. The rebound of vision may occur months or years after surgery, and the specific time varies with individual differences.
Vision rebound is also a risk of myopia surgery, which requires patients to fully communicate with doctors before surgery to understand the possible situation and solutions. Doctors will make more accurate assessments and suggestions based on individual conditions to help patients make decisions.
Risk 4: Poor surgical effect
Although the success rate of myopia surgery is high, there are still a few patients who may have poor surgical results. Poor surgical results may be manifested as no significant improvement in vision, large fluctuations in vision after surgery, and other visual problems after surgery. These conditions may be related to many factors, such as surgical techniques, individual differences, and postoperative recovery.
Although poor surgical results may have some impact on patients' expectations and life, they can usually be improved through further examination and treatment. After a period of time, if the patient is not satisfied with the surgical effect, he can consult with the doctor to seek further solutions.
To sum up, although myopic surgery has good results in correcting vision, there are also certain risks. Complications during the operation, vision problems after the operation, corneal refractive instability and poor surgical results all need to be fully communicated with the doctor before the operation to understand the risks and solutions. In addition, postoperative eye protection and regular follow-up are also very important to reduce risks and promote recovery.
