introduction of the synthetic plastic poly(methyl methacrylate) as a
material for artificial cornea (keratoprosthesis) is usually credited to
William Stone, Jr. who allegedly performed the first experiments in 1947
and reported the results in 1953
Keratoprosthesis is a surgical procedure where a severely damaged or
diseased cornea is replaced with an artificial cornea while conventional
cornea transplant uses donor tissue for transplant, an artificial cornea
is used in the keratoprosthesis procedure.
The surgery is performed to restore vision in patients suffering from
severely damaged cornea due to congenital birth defects, infections,
injuries and burns.
There are currently two different types of artificial corneas that have
been approved by the U.S. food and drug administration to restore vision
the dohlman artificial cornea combines a donocorneawith man-made
materials to increase compatibility.
The alphacor device is covered by the patientís own tissue for a period
of time to promote healing and integration of the device to the ocular
tissues both of these options are still being perfected, but have
demonstrated clinical success and continue to be promising alternatives
to corneal transplants using donor tissue alone.
A patient's eyeball, and, at an upper portion thereof, an optical
portion adapted to be exposed through an anterior portion of the
The optical portion having a diameter less than that of the cylindrical

the optical portion of the cornea body and seated on the step
An anterior flange coupled to an upper surface of the skirt, and a
support member attached to a lower end of the cylindrical portion and
adapted to support the artificial cornea body.
An amnion is covered on the implant in order to promote a stable graft

reaction period for the recovery of a cut portion of the patient's
The piece is placed on the eye where cells and blood vessels grow in the
holes and ensure the artificial cornea remains anchored
Plastic replacements have been available for decades, but their
implantation is still plagued by side effects such as infection and
They remain a last resort option for patients where all other options
have failed, including donor transplants," says joachim storsberg at the
fraunhofer institute for applied polymer research in potsdam, germany.
Storsberg is developing plastic implants but was not involved with the
Several other research groups are working on artificial corneas made
from materials that encourage cell growth and are less likely to be
But this is the first time the long-term effectiveness of such an
implant has been tested in humans with their help think we are
continuing our journey towards an age when medicine can regenerate or
replace absolutely any part of your body.
