Is the therapeutic effect of femtosecond surgery lasting?
Femtosecond surgery, also known as excimer laser surgery, is an ophthalmic surgery used to correct myopia, hyperopia and astigmatism. It uses a specially designed laser device to improve vision by rapidly and accurately reshaping the cornea. Many people are attracted to this operation because it is considered a lasting treatment. This article will elaborate the therapeutic effect of femtosecond surgery from four aspects: postoperative expectations, long-term efficacy, postoperative recurrence and hospital cases.
Postoperative expectations
The expected effect of femtosecond surgery is to get rid of the dependence of glasses and contact lenses and restore natural vision. Before the operation, the doctor will conduct a detailed eye examination and assessment of the patient to determine the suitable population for the operation. Generally speaking, the vision after surgery will improve rapidly, and many patients can feel the improvement of vision on the first day after surgery.
However, the recovery period after surgery varies from person to person. Some patients may have mild discomfort such as dryness, photosensitivity and vision fluctuation, but these symptoms usually disappear within a few days to weeks. Most patients can recover to stable vision within one month.
Long term efficacy
The therapeutic effect of femtosecond surgery is generally lasting. Research shows that the vision of most patients after surgery can last for several years or even decades. However, this does not mean that vision will not change after surgery. As people grow older, their eyesight may decline to some extent, and femtosecond surgery cannot stop this process.
Nevertheless, the effect of femtosecond surgery on improving vision is still significant. Many patients report that their vision has improved significantly after surgery, and they can better see distant or near objects. This lasting effect makes many people choose femtosecond surgery as the preferred method to treat myopia and other ophthalmic problems.
Postoperative recurrence
Although most patients can enjoy long-term vision improvement after surgery, a few patients may have postoperative recurrence. Some studies have shown that about 1-5% of patients may need a second operation to further improve their vision.
The causes of postoperative recurrence may include improper surgical techniques, eye diseases, corneal tissue changes, etc. Therefore, when selecting hospitals and doctors, patients should choose experienced professional doctors and hospitals with advanced equipment to reduce the risk of postoperative recurrence.
Hospital cases

In general, femtosecond surgery is an effective method to treat myopia, hyperopia and astigmatism, and its therapeutic effect is lasting in most patients. Although there is a risk of recurrence after surgery, selecting experienced doctors and hospitals can reduce this risk. Therefore, patients should carefully select hospitals and doctors before accepting femtosecond surgery, and understand the possible risks and effects of surgery.
Conclusion: As a kind of ophthalmic surgery for myopia, hyperopia and astigmatism, femtosecond surgery has a lasting effect. After surgery, most patients can enjoy the effect of improving their vision in a long time. Although there is the possibility of postoperative recurrence, selecting an experienced doctor and hospital can reduce this risk.
