Definition

Phacoemulsification cataract surgery is a procedure in which an ultrasonic device is used to break up and then remove a cloudy lens, or cataract, from the eye to improve vision. The insertion of an intraocular lens (IOL) usually immediately follows...

Physiology of the Cornea

Most laser vision correction procedures like LASIK involve shaping the cornea so that light can be properly focused on the back of the eye, or retina. This video shows how the anatomy of the eye works to harness light so that we can see. The role of the cornea in vision is also discussed.

How LASIK eye surgery is carried out

Crisp images from our world require that light is focused on the back of the eye. When light cannot focus properly, it is called an error of refraction and is often caused by an irregular or improperly shaped cornea. LASIK improved errors of refraction in the eye by reshaping the cornea, as the animation explains.

In a phacoemulsification procedure, an incision is first made in the cornea, the outer covering of the eye (A). A phacoemulsification instrument uses ultrasonic waves to break up the cataract (B). Pieces of the cataract are then suctioned out (C). To repair the patient's vision, a folded intraocular lens is pushed through the same incision (D) and opened in place (E).

Other Information

Phacoemulsification refers to modern cataract surgery in which the eye's internal lens is emulsified with an ultrasonic handpiece, and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution, thus maintaining the anterior chamber, as well as cooling the handpiece.


Other Information

Surgeons aim for results of 20/20 or better so that you can perform most daily activities without your glasses. However, there is a possibility that after surgery, you may need to wear reading glasses or corrective lenses for at least some activities.
