The patient must refrain from eating and drinking for 12 hours before the operation.

The ophthalmologist performs a small incision in the cornea, then breaks up the clouded lens using a high frequency ultrasound device, then removes the broken parts of the lens completely and replaces it with a new artificial lens that is firmly fixed behind the pupil and iris, after that the small incision is then closed and the eye is covered with a bandage to protect it during the first days after the surgery.

  • After the surgery:

The patient can leave immediately after the surgery, and it is preferred with the company of a friend or acquaintance, because of his inability to drive.

During the first week, the patient's affected eye will be protected by wearing protective shield; to avoid rubbing it and to protect it from any external effect such as dust or sunlight. It can cause some itching in the first few days following the surgery. Also, it is important to use an eye-drop for weeks after the surgery according to the doctor's consult.
