Does cataract surgery require sutures?

Under normal circumstances, most cataract surgeries do not require sutures, although a small number of complex cases may need them. If in doubt, it is recommended to consult a doctor in advance. The detailed explanation is as follows:

If the standard phacoemulsification cataract surgery is performed, the incision is small (typically 2–3 mm), and the wound can close on its own after surgery, so sutures are not required. This type of surgery causes minimal trauma and allows for rapid recovery. Patients usually experience little discomfort during healing, and only need to protect the eye postoperatively by avoiding external impacts—there is no need to worry about suture-related issues.

However, if extracapsular cataract extraction or another technique is used due to factors such as a very hard lens nucleus or special ocular conditions, the incision will be larger (usually 5–6 mm), and sutures may be necessary after surgery. Suturing helps align the wound properly and promotes healing, reducing the risk of postoperative complications. However, recovery takes longer, and patients must attend follow-up appointments as instructed so that the doctor can determine the appropriate time for suture removal.

Prior to cataract surgery, patients should discuss the surgical approach with their doctor. After surgery, avoid rubbing or pressing the eye and maintain good ocular hygiene. If symptoms such as redness, pain at the incision site, or sudden vision loss occur, seek medical attention promptly.
