Cataract surgery incisions usually take 3 months to fully heal. Cataracts are a common disease of the eye and are by far the most common cause of vision loss in middle-aged and elderly people and can be treated with surgery. Surgery involves making tiny incisions at the junction of the black and white eyeballs, removing the cloudy lens from inside the eye and implanting a clear artificial lens to restore vision. The surgical incision is self-closing and usually does not require stitches, but the incision site takes longer to fully heal due to the lack of blood supply and takes about 3 months after surgery to fully heal. During the recovery period after cataract surgery, patients must be careful not to expose their eyes to external stimuli, especially not to rub and squeeze the eyeball, which may cause the surgical incision to crack. In addition, it is important to maintain eye hygiene and not to allow dirty water from washing hair and face to enter the eye and cause infection.
