In cataract surgery the capsular bag is opened and the cloudy lens is removed by ultrasound energy. An artificial lens is placed in the bag. Most of the time, no sutures are needed as the wound is self-sealing and the patient will see better the day after surgery. In more advanced cataract cases, the clearing of the vision may take longer as more ultrasound energy is necessary. There are many options to insert special lenses (e.g. lenses to correct astigmatism or lenses to correct presbyopia) that will allow to free you from spectacles. Also there is the option of using a femtolaser cataract system to assist in the surgery.
