Does laser myopic operation effect last?
Laser myopia surgery is a common method to treat myopia at present. It can correct vision by using laser technology to change the corneal curvature of the eye. However, many people have doubts about whether the effect of laser myopia surgery is lasting. The following is an analysis of the durability of the effect of laser myopia surgery from several aspects.
1. Postoperative visual stability
Laser myopic surgery can significantly improve the vision of myopic patients in a short time, but the key is the stability of vision after surgery. According to clinical research, laser myopia surgery generally achieves the best vision within one year after the surgery, and then the vision changes relatively stable. The vision of most surgical patients can still remain at an ideal level 5 years after surgery, which means that patients can enjoy a clear vision effect for a long time.
However, individual differences exist, and a few patients may experience slight vision fluctuations within a few years after surgery. Generally, this fluctuation is acceptable, but if the vision drops beyond a certain range, repair surgery or corrective glasses may be required.
In addition, age is also a key factor affecting the stability of vision. The patient is too young at the time of surgery, which may lead to myopia again due to immature eyes with age. Therefore, the doctor will consider the patient's age when evaluating the suitability of the operation.
2. Long term effect of laser myopia surgery
The effect of laser myopia surgery can generally last for decades. According to many clinical studies, the effect of most myopic patients after surgery can be maintained to 40 years old or longer. This means that patients can not use corrective glasses or contact lenses for a long time.
However, with the growth of age, presbyopia has become a common problem. Even if there is no laser myopia surgery, people will need to correct myopia and presbyopia as they grow older. Laser myopia surgery can not prevent or reverse presbyopia, but it can eliminate or reduce the impact of myopia on life when young.
3. Precautions and risk factors
Although the effect of laser myopia surgery is usually lasting, patients need to pay attention to some matters and risk factors before surgery.
First of all, a detailed ophthalmic examination should be carried out before the operation to ensure the suitability of the operation. The corneal thickness, diopter, eye shape and other factors of patients will affect the effect and safety of surgery.
Secondly, recovery and nursing should be carried out in strict accordance with the doctor's recommendations after the operation. Patients need to return to the hospital regularly to maintain good living habits and eye hygiene, avoid strenuous exercise and eye injuries, and reduce the risk of surgery.
Finally, the operation itself has certain risks, such as intraoperative infection, dry eye, corneal scar, etc., but these risks are usually very rare, and can be reduced through preoperative evaluation and postoperative nursing.
4. Conclusion
The effect of laser myopic surgery is usually lasting and can significantly improve the vision of myopic patients. Most patients can maintain the ideal visual effect within 5 years and longer after surgery. However, individual differences and age factors will still have an impact on the effect, and patients need detailed assessment and consultation before surgery. In addition, the operation itself has certain risks, and patients need to strictly follow the doctor's recommendations for recovery and care.
In short, accurate surgical indications and postoperative recovery nursing are the key to maintain the lasting effect of laser myopia surgery. Choosing a regular and experienced laser ophthalmic hospital for surgery and following the doctor's guidance and suggestions will help patients obtain the best surgical effect and long-term visual stability.
