Phacoemulsification is a well-established surgical procedure used to treat cataracts, which occur when the lens of the eye becomes cloudy, resulting in impaired vision. This technique involves using ultrasound waves to break up the cloudy lens into smaller pieces, which can then be gently suctioned out of the eye. Following the removal of the cataract, an artificial intraocular lens (IOL) is typically implanted to restore clear vision.

The procedure is highly effective and is commonly performed on an outpatient basis. It allows for quick recovery times, and many patients notice improvement in their vision almost immediately after surgery. Phacoemulsification is favored for its precision and the ability to minimize trauma to surrounding structures in the eye.

In contrast, other options listed are procedures with different indications that do not primarily address cataracts. For example, laser-assisted in situ keratomileusis (LASIK) is a refractive surgery aimed at correcting vision by reshaping the cornea, not treating cataracts. Keratoplasty, or corneal transplantation, involves replacing a damaged cornea, and trabeculectomy is a procedure designed to lower intraocular pressure in patients with glaucoma. Therefore, phacoemulsification stands out as the appropriate and common surgical procedure
