the results are reduced. Therefore Prelex is safer than cataract surgery.
After Cataract surgery implants may or may not be inserted. If
inserted most are a monofocal type lens. Prelex requires Presbyopic
implants (Pi). In the United States, Cataract surgery is partially
covered by medical insurance. Prelex is considered an elective lifestyle
procedure and therefore currently not covered.

Who can have Prelex?

Prelex is a great and relatively safe alternative for individuals’ ages
forty-five and above looking to decrease or eliminate dependency on
glasses and contacts. Prelex can be performed even if a patient is
nearsighted, farsighted, or has astigmatism. A person who does not
want to wear readers nor glasses for distance or near is good
candidate. It can even be performed if a person previously had Lasik,
Radial Keratotomy (RK), CK or various other surgeries. The aim is to
rejuvenate the eyes and regain the full range of vision. This means, if
you are on a hiking trip you can pull out a map and read it without
glasses. Or if you are a pilot, you may still retain your license without
worrying about not seeing all those fancy dials.
The Prelex procedure is the process of replacing the patient's
dysfunctional natural lens with an artificial Presbyopic implant (Pi).
The newly implanted lens will provide clear vision at all distances,
without the use of glasses. An additional advantage to Prelex surgery
is that once you have had the procedure, you will not require cataract
surgery later in life, as cataracts are unable to develop in an artificial
lens.

Is it a painful, long procedure?

The anti-aging Prelex procedure itself is brief and painless taking
only 5 to 10 minutes. Prior to the surgery the patient will be given a
small dose of an oral pill such as Xanax to relax the patient and
mitigate surgical anxiety. The patient will also get anesthetic numbing
drops, which are dropped into the eye to ensure the patient will feel
no pain for the duration of the surgery even though the person is
awake. The eyes are securely kept open using eyelid retainers. This
allows for the surgeon to work cautiously without the possibility of
the eye blinking or closing. The recovery time after the procedure is
