Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the volume of the anterior chamber during the procedure.
In this a glued IOL is placed behind the cataract pieces. The glued IOL then works as a scaffold and the cataract pieces are removed with the phaco handpiece using ultrasound. Two partial thickness scleral flaps measuring 2.5 to 2.5 mm are made 180 degrees diagonally apart. Infusion is placed by anterior chamber maintainer and sclerotomies are ...
Phacoemulsification uses a machine with an ultrasonic handpiece with a titanium or surgical stainless steel tip, which vibrates at an ultrasonic frequency—commonly 40 kHz—to emulsify the lens tissue, which is aspirated by a coaxial annular suction tube. A second instrument, which is sometimes called a "cracker" or "chopper", may be used ...
The technique has mostly been replaced by extracapsular cataract surgery, including phacoemulsification. [25] The lens can also be removed by suction through a hollow instrument: bronze oral-suction instruments that seem to have been used for this method of cataract extraction during the 2nd century CE have been unearthed.

Charles David Kelman (May 23, 1930 – June 1, 2004) was an American ophthalmologist, surgeon, inventor, jazz musician, entertainer, and Broadway producer. Known as the father of phacoemulsification, [1] [2] he developed many of the medical devices, instruments, implant lenses and techniques used in cataract surgery.
The Trabectome handpiece is inserted into the anterior chamber, its tip positioned into Schlemm's canal, and advanced to the left and to the right. Different from cautery, the tip generates plasma to molecularize the trabecular meshwork and remove it drag-free and with minimal thermal effect.
