'Phakic' refers to an eye that still has it's natural lens in place. 'Aphakic' refers to an eye that has had its natural lens removed. Therefore, a Phakic IOL is an artificial Intraocular Lens (IOL) that is implanted inside the eye without removing the eye's natural lens.
Both the cornea and the lens are responsible
for focusing light images on retina. The most
common forms of refractive surgery, PRK and
LASIK, change the focusing power of the eye
by removing the tissue from the cornea. For
those who were too nearsighted or farsighted
to have their corneas reshaped, an
intraocular procedure that replaced the
natural lens with an IOL was the only viable
alternative - until now.
Phakic IOLs are ideal for younger patients
whose natural lens can still change shape.
Phakic IOLs can be thought of as implantable
contact lenses. Some Phakic IOLs are designed
to be placed in front of the iris (colored
part of the eye) while others are designed to
be placed behind the iris.
Performed as an outpatient procedure, the IOL
is placed inside the eye through a very
small, self-sealing incision. You will remain
comfortable as the eye is completely
anesthetized. Everyone heals differently, but
many patients report improvement in their
vision almost immediately, and most resume
their normal activities within a day or two.
One eye is done at a time, and the second eye
is usually done in a week or two.
