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.
Individuals suffering from cataract and have vision problems.
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:

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