Under the action of ultrasound, two (or more than two) immiscible liquids are mixed uniformly to form a dispersion system, one of which is evenly distributed in the other liquid to form an emulsion. Ultrasonic emulsification is also widely used in various fields, playing a more important role.

Ultrasonic emulsification equipment is commonly used in the pharmaceutical industry and daily necessities industry to manufacture various emulsion products, such as emulsion drugs, cosmetics and shoe polish. Ultrasonic emulsification method can also be used to make emulsified combustion products of oil (gasoline, diesel, etc.) and water or pulverized coal to increase the combustion value of unit fuel.

Using the device, through a corneal or scleral incision with a size of 3-5mm, the lens nucleus is crushed by ultrasound to make it chylo-like, and then sucked out together with the cortex. After the operation, the posterior lens capsule is retained and the posterior chamber intraocular lens can be implanted at the same time.

Compared with traditional cataract surgery methods, phacoemulsification surgery has better surgical results and has become an internationally recognized and reliable cataract treatment method.
