The first part of the procedure involves removing the old lens through a process called phacoemulsification.
In laymen’s terms, a device roughly the size of a pen tip is inserted through the cornea. Using high frequency sound waves, the cataract is broken up into small fragments that are immediately suctioned away.
This process clears the way for a new lens to be inserted, which will restore your vision and get rid of the cloudy vision you have been experiencing.
After the natural lens is removed, an intraocular lens (IOL) is inserted through the incision in the cornea using an injector tool. The lens is inserted right where the natural cataract lens used to be.
Slight adjustments are typically made to align the lens with the patient’s astigmatism (based on measurements taken before surgery), and at that point the lens is in place and ready to go.
Patients may experience a feeling of pressure on the eye, but most patients do not describe the experience as painful or unpleasant in any way.
