After myopia became an operation, can you be blind when you are old?

Myopia surgery itself is a method to correct myopia. Whether the eyes are blind or not mainly depends on many diseases of the eyes, such as macular damage, optic nerve damage, diabetic retinopathy, acute optic neuritis, glaucoma and other diseases, which may lead to blindness. However, myopia surgery itself may not be a problem. Myopia surgery does have some complications. For example, laser surgery, whether femtosecond, full femtosecond, semi-femtosecond or full laser, needs to remove part of the cornea to form a lens. When the operation is young, the patient may not feel much. Some elderly patients have poor lens compensation function, which may make up the difference, and may make presbyopia feel very uncomfortable in the future.

Whether the patient is really blind is not caused by surgery. Other eye diseases may occur. The most acute disease caused by eye diseases is central artery occlusion, and patients may be blind within 24 hours, followed by venous bleeding, acute optic neuritis and acute glaucoma, which may make patients blind within a week at any time. There are also some chronic glaucoma, chronic ischemic optic neuropathy, retinal and macular degeneration. Patients with these diseases are all chronic injuries, and patients may be blind. The above diseases are caused by the development of the disease itself, and have little to do with the patient's myopia. Don't think that myopia leads to blindness, so be sure to avoid misunderstanding.
