One technique is called phacoemulsification in which high-frequency sound vibrations (ultrasound) are used to soften and liquefy the lens so it can be aspirated through the needle. Phaco Cataract removal has become very popular, precise and short in time and most liked by the patient and the doctor.

A laser cannot remove a cloudy lens or make it clear again. However, some doctors may use a laser to open the front part of the lens capsule before removing the lens or to help patients who develop "after-cataract." (See "What happens after surgery ?")

Cataract surgery is one of the most successful operations done today-more than 90 percent of the people who have this surgery find that they can see better. Complications may occur, but most are treatable. Serious complications that threaten vision are rare.

Certain people may not benefit much even after cataract surgery. They include people whose cataracts are hypermature with Glaucoma and whose vision is impaired by another eye disease as well.

In summary, each cataract patient should discuss the possibility of surgery with the doctor who examines his or her eyes to determine whether the potential benefits of cataract surgery outweigh the risks. It is also very important to decide in advance, with the help of the doctor, what form of substitute lens would be most suitable.
