How It Is Performed
Cataract eye surgery or cataract surgery is usually performed under local anesthesia. The eye is numbed with an injection or by using anesthetic eye drops.
During cataract surgery, a cloudy natural lens is removed and replaced with a clear artificial lens. The eye doctor firstly creates two incisions into the clear cornea of the patient. A circular hole is then created into the capsule where the artificial lens is located. At this point, ultrasound waves may be used to liquefy the lens, after which it is removed. The soft outer layer of the cataract is also removed. Saline solution is inserted into the front part of the eye to help it maintain its shape. A plastic lens is then inserted into the eye where the natural lens used to be. The eye doctor may also inject antibiotics in that area in order to prevent any risk of infections
The cataract surgery recovery time is usually quite short. Patients can leave the hospital in one or two days. Heavy physical activities and lifting need to be avoided for around 4 weeks after the cataract surgery. Doctors recommend wearing an eye shield, especially while sleeping for a few days after the procedure.Patients need to be followed the cataract surgery aftercare carefully advises given by their doctors to have a comfortable recovery

No pain is felt during the operation due to anesthesia, and mild to moderate pain after surgery can be easily relieved with prescription drugs
