About Cataract

Cataract surgery is a very common procedure treating cataract. A cataract is a clouding of the lens in the eyes leading to a decrease in patient’s vision or causing vision loss that cannot be corrected with glasses, contact lenses or corneal refractive surgery like LASIK.


In general cataract surgery involves removing the clouded lens and in most cases replacing the natural lens of the eye with an artificial intraocular lens called IOL. However, in some rare circumstances, intraocular lenses may not be inserted.

Before Cataract

Eye examination before surgery is required. The ophthalmologist will measure eye to set the proper focusing power for your IOL if needed. These tests are done by ultrasound or LOLMaster machine. Also, you will be asked about any medicines you take. You might be asked not to take some of these medicines before surgery.


You may be prescribed antibiotic eye drop some days before the surgery. This will reduce the risk of infection and swelling during and after surgery. Other recommendations are:


  • Wash your eyelids and eyelashes the night prior to surgery
  • Avoid wearing eye makeup 48 hours before surgery 
  • Do not eat too much breakfast on the day of surgery. Eat a light dinner the night before and water in the morning.
  • Some doctors recommend to be fast on the day of surgery. 


How is Cataract performed?

The doctor first will place eye drops in the eye to dilate the pupil. A local anesthetic is then used to numb the area. Sedation are given to some patients to help them to 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. In some cases, however, a cataract may be removed without implanting an artificial lens. Surgical methods used to remove cataracts are: using an ultrasound probe to break up the lens for removal, using an advanced laser technique to remove the cloudy lens or making an incision in the eye and removing the lens in one piece.

Recovery procedure

Possible discomfort

Expect temporary worsening of the vision immediately after surgery. The vision begins improving within a few days while eyes are healing. Some patients feel itching and mild discomfort for a couple of days.


Colors may seem brighter after the surgery because of a new and clear lens. A cataract is usually yellow- or brown-tinted before surgery, muting the look of colors. It takes time to get used to it.

Post procedure care

Recovery after cataract surgery is usually very quick, and most patients notice clearer vision within few days of the procedure. It is recommended to

  • Have help getting back to the hotel.
  • Not doing heavy activities for the first 2 to 3 days.
  • Wear eye shield for few days after the surgery.
  • Take medication or prescribed eye drops on time.
  • Avoid lift heavy stuffs up to 4 weeks after the surgery.
  • Not rub eyes.
  • Wear sunglasses when you are outdoor
