What degree of myopia is suitable for laser eye surgery?

In general, myopia surgery is typically suitable for patients with myopia ranging from 100 to 2000 degrees. However, whether a patient is eligible for myopia surgery depends on several factors, including age requirements, stability of the refractive error, ocular health, and corneal thickness.

Patients are usually required to be at least 18 years old, as the eye is relatively developed and the myopia degree tends to stabilize after this age, making significant changes less likely. The myopia degree should remain relatively stable for the past two years, generally with a change of no more than 50 degrees. This ensures surgical effectiveness and prevents continued myopia progression after surgery. Patients must undergo comprehensive eye examinations to ensure they do not have ocular diseases such as conjunctivitis, dry eye syndrome, or glaucoma, which may affect surgical outcomes or increase surgical risks.

Corneal laser surgery has certain requirements regarding corneal thickness. Usually, the corneal thickness should be above 500 micrometers. If the corneal thickness is insufficient, corneal laser surgery may not be an option, and alternative procedures such as implantable collamer lens surgery should be considered. Although myopia surgery can correct myopia within a certain range, it cannot completely cure myopia.

When considering myopia surgery, patients should visit the ophthalmology department of a reputable hospital for comprehensive examinations and evaluations, follow professional medical advice, and choose the most suitable surgical procedure. After surgery, patients still need to maintain good eye habits, avoiding prolonged near work and excessive use of electronic devices, to preserve ocular health.
