Recently, many patients will ask when exactly to have cataract surgery.
Generally speaking, cataract surgery can be considered when the visual acuity is below 0.5, but sometimes patients with 1.0 visual acuity will also ask for surgical treatment, this is because the visual acuity of 1.0 only means that they can see the line of 1.0 visual acuity table, but it may be very blurred to see, the imaging is not clear. The cataract can also be surgically removed to get a clear vision. Therefore, there is no strict standard for when to have surgery, it depends on the patient’s requirements for his or her visual quality.
However, we should be careful not to operate only when the cataract is particularly mature and hard, because the operation will take a long time and the recovery will be slow. If your vision has decreased significantly, even to manual or exponential vision, then the cataract is too heavy. Don’t treat cataracts until you can’t see.
