The need for stitches may be due to a large cataract surgery incision or a poor watertightness of the incision, in order to avoid leakage of the incision suture. Currently, cataract surgery is very mature, usually using ultrasonic emulsification technology to break up the cloudy lens and then suctioned out of the eye, the operation time is short, the incision is also small, usually do not need stitches. In special cases, cataract surgery requires stitches. If the patient’s crystalline nucleus is very hard, the surgical incision will be made larger, the wound healing is more difficult, and the healing time is long, in this case, stitches are needed; the surgical incision has poor watertightness, and there is a risk of leakage after the operation, in order to avoid complications, stitches are also needed. Patients with cataract surgery stitches have a relatively long recovery time, and must pay attention to eye hygiene and good eye habits after surgery to avoid bacterial infections.
