Is the vision after cataract surgery the same as normal vision?

Many friends who have cataracts will ask the doctor a question before doing cataract surgery: How much can my vision reach after this operation?

First of all, this answer varies from person to person, and it is not necessarily that excellent eyesight can be achieved after cataract surgery.

The human eye is like a camera, and the lens is the lens of the camera. When a person has a cataract, it is equivalent to mixing the lenses of the camera, which affects the entry of light.

Cataract surgery is equivalent to changing the lens of the camera, and light can naturally enter the eyes to achieve the purpose of restoring vision.

1, how much vision can be achieved after surgery generally depends on the fundus function, which is similar to the level of camera pixels. The better the fundus function, the better the vision recovery.

Secondly, with different lenses, the effect we get is naturally different. Generally speaking, after the operation of a monofocal lens, glasses are needed to realize barrier-free life, while after the operation of a trifocal lens, clear vision in the far, middle and near range can be obtained without glasses. In addition, there are bifocal crystals for patients with different needs to choose from.

Finally, the intraocular lens we replaced in cataract surgery can be used for life, which is equivalent to our second pair of "eyes" for life. Patients should carefully choose the appropriate intraocular lens after full communication with doctors.
