cataract extraction techniques

Cataract extraction is a surgical procedure to remove cloudy lenses from the eye, which affects vision. The most common method is phacoemulsification, where the surgeon uses an ultrasonic device to break up the cataract into tiny pieces for easy removal. Another method, extracapsular cataract extraction, involves making a larger incision to remove the lens in one piece. After the cataract is removed, an artificial lens, called an intraocular lens (IOL), is often placed to restore clear vision. The procedure is usually quick, performed under local anesthesia, and has a high success rate.
