Is laser eye surgery for myopia good?

In general, laser eye surgery for myopia is an effective method for correcting nearsightedness, offering multiple advantages, although certain risks are involved.

Laser surgery improves vision by precisely reshaping the corneal curvature, allowing patients to achieve clear vision. Many patients experience noticeable visual improvement within a few days after surgery. The procedure typically takes only several to十几 minutes, with a relatively quick recovery period. For minimally invasive techniques such as SMILE (small incision lenticule extraction) and femtosecond LASIK, the recovery period may require approximately half a month to one month, depending on individual physical conditions and the surgical method used. Compared with traditional eyeglasses or contact lenses, laser surgery reduces eye discomfort and dependency, thereby improving quality of life. It is particularly suitable for individuals who dislike wearing glasses or contact lenses, or those whose professions or sports activities make wearing glasses inconvenient.

However, it should be noted that laser surgery may damage some nerve fibers on the ocular surface, affecting tear secretion and distribution, which can lead to dry eye syndrome. Nevertheless, due to its small incision, SMILE causes less damage to corneal nerves, resulting in a relatively lower incidence of dry eyes. Some patients may experience night vision deterioration, glare, or halos after surgery, which may be related to changes in corneal shape. If sterilization during surgery is inadequate or postoperative care is improper, corneal infection may occur. Therefore, strict adherence to prescribed medications and regular follow-up examinations after surgery is necessary.

When considering laser surgery, patients should fully understand the risks and expected outcomes, choose reputable hospitals and experienced surgeons for the procedure, and strictly follow medical instructions for preoperative preparation and postoperative care. Additionally, maintaining good eye habits after surgery is important.
