Cataract surgery is performed by an ophthalmic surgeon or ophthalmologist and is a fairly straightforward procedure. It is usually done while the patient is awake and takes around 30 to 45 minutes to complete. A local anesthetic is applied to the eye to ensure patients do not feel pain during the procedure and patients may also receive medication to help them relax.
Most cataract surgeries use a technique known as phacoemulsification. When using this technique, medical professionals begin the procedure by putting drops in the eye to dilate the pupil. A small cut is then made in the cornea, which is the transparent tissue in the front of the eye. Through this cut, surgeons place a small probe that uses ultrasound waves to break up the affected lens. The lens pieces are then removed and a small plastic lens is put in its place.
The lens may also be removed using an extracapsular cataract extraction technique. With this technique, a large incision is made in the cornea and surgeons remove the front capsule and cloudy portion of the lens using surgical tools. The back capsule of the lens is left intact and supports the artificial lens.
