Phakic IOL
The Food and Drug Administration (FDA) recently approved an
implantable lens that helps correct moderate to severe
nearsightedness and allows the patient to return to normal daily
activities relatively quickly. The Phakic Intraocular Lens (IOL)
reduces the need for glasses or contact lenses by correcting your
vision inside the eye, without removing the eye's natural lens.
Clear Lensectomy (Refractive Lensectomy or clear lens extraction)
may be an appropriate option for people who find their
prescription falls outside the accepted range for laser refractive
procedures, have extreme near or farsightedness, or who may
otherwise not be an ideal candidate for vision correction
procedures. Clear Lensectomy involves the removal of the natural
lens in your eye and replacing it with an Intraocular Lens (IOL),
resulting in improved near and distance vision.
How Phakic IOLs Work
Phakic IOLs are inserted in the eye and correct refractive errors
by focusing light properly on the retina, the sensory tissue on
the back of the eye. Because people who are nearsighted have
difficulty focusing light and images properly, distant objects
come to focus in front of the retina instead of on it, making them
appear blurred or out of focus. When a Phakic IOL is implanted, it
corrects this by bending and focusing light directly on the retina
reducing the need for contacts and glasses. The procedure is also
fully reversible.
Phakic IOL Surgery
As with any vision correction surgery, a comprehensive examination
with your eye care professional is necessary to determine if you
are a candidate. Patients may be asked to discontinue wearing
contacts several weeks before the examination so an accurate
reading of your prescription can be taken. Others may need to
schedule a procedure prior to surgery which will help manage the
pressure within the eye after the IOL has been implanted.
Phakic IOL surgery is an outpatient procedure. During the surgery,
your doctor may use eye drops or injections to numb or prevent
movement of the eye. A precise incision will allow the doctor to
insert the Phakic IOL in front of or just behind the colored part
of the eye (iris). A bandage contact lens and a clear eye patch
will be used to cover and protect the eye until your doctor feels
it is ok to remove.
After The Procedure
Phakic IOL surgery, although minimally invasive and relatively
brief, is a serious procedure. Because the incision used to insert
the IOL is so small, sutures are often not required and post
operative discomfort is minimal. Your vision may also be somewhat
hazy or blurry immediately following the surgery and you may
notice an increased amount of sensitivity to light. Your
scheduled, post-operative visits with your doctor will determine
if you will require any additional follow up care.
