Question By: Cataract surgery is a common procedure used to treat cataracts, which is a condition that causes the natural lens of the eye to become cloudy and eventually impair vision. There are two main types of cataract surgery:
Phacoemulsification: This is the most common type of cataract surgery. In this procedure, the surgeon makes a small incision in the eye and uses a machine that emits high-frequency sound waves to break up the cloudy lens. The pieces of the lens are then removed through the incision, and a new artificial lens is inserted in its place. Phacoemulsification is a quick and efficient procedure that typically requires only a few minutes to complete.
Extracapsular cataract extraction: This type of surgery is less commonly used today but may be necessary in cases where the cataract is very advanced. In this procedure, the surgeon makes a larger incision in the eye and removes the cloudy lens in one piece. The new artificial lens is then inserted in the same way as with phacoemulsification. Extracapsular cataract extraction requires a longer recovery time than phacoemulsification.
Both types of cataract surgery are generally safe and effective, and most patients experience a significant improvement in their vision following the procedure. The choice of which type of surgery to use depends on factors such as the severity of the cataract and the patient's overall health.
