Cataract surgery on 1 eye is a 30-minute day procedure performed in the hospital. Surgery for the right and left eye is performed on separate days. Having surgery done on both eyes at the same time is not recommended because of potential complications such as infections affecting both eyes.
You may be instructed not to eat or drink anything 6 hours before cataract surgery. Your doctor may also advise you to temporarily stop taking any medication that could increase your risk of bleeding during the procedure. You will also need to apply eye drops before the procedure to prepare your eye. Let your doctor know if you take any medications for prostate problems, as some of these drugs can interfere with cataract surgery.


First, your doctor will place eyedrops in your eye to dilate your pupil. You'll receive local anaesthesia to numb the area, and you may be given a sedative to help you relax. If you're given a sedative, you may remain awake, but groggy, during surgery. During cataract surgery, the clouded lens is removed, and a clear artificial lens is usually implanted.
After cataract surgery, expect your vision to begin improving within a few days. Your vision may be blurry at first as your eye heals and adjusts. Colours may seem brighter after your surgery because you are looking through a new, clear lens. A cataract is usually yellow- or brown-tinted before surgery, muting the look of colours. You'll usually see your eye doctor a day or two after your surgery, the following week, and then again after about a month to monitor healing.
It's normal to feel itching and mild discomfort for a couple of days after surgery. Avoid rubbing or pushing on your eye. Your eye doctor may ask you to wear an eye shield on the day of surgery.

She may also recommend wearing the eye shield for a few days after your surgery and the protective shield when you sleep during the recovery period. Your eye doctor may prescribe eyedrops or other medication to prevent infection, reduce inflammation and control eye pressure. After a couple of days, most of the discomfort should disappear. Often, complete healing takes 4 to 6 weeks.
