Artificial Eyes (Prosthetic Eye) have for many years prior to the advent
of WW 11 been constructed of glass by artisans from Europe. These eyes
were made from silica (glass) and fire formed such as a light bulb. They
were virtually a vacuum that was fragile and would etch from body acid,
causing replacement much more often than a plastic (Prosthetic Artificial Eye).
After WW11 the availability of silica from Europe became very difficult
to obtain. Other materials and methods became necessary to fabricate the
Prosthetic Artificial Eye. This instituted 3 teams from the Military Dental
Departments to develop and solve this problem. These teams consisted of
personnel who were experienced in the prosthetic field in working with
plastics and art forms. They were chosen from the Dental Prosthetic Schools
of Bethesda Naval Training Center and Walter Reed Army Hospital in Washington
D.C. They collaborated in their development of the modern day Prosthetic
Artificial Eye. This decision was made due to the eye loses of our military
at that time. These methods were passed on to the civilian industry by
persons who gained this expertise while in the military.
The present day Prosthetic Artificial Eyes are made from (methyl –methacrylate)
commercially known as ACRYLIC. This is a synthetic compound that is in
two parts. Monomer (liquid) and (Polymer (powder), they are mixed to produce
a putty like consistency, then packed in a compression mold to be cured
to solidity. This forms the base for the application of the cosmetic duplication
of the natural eye. All applications are in a vehicle of the same material,
so that they have the same chemical bonding capability. This makes a totally
solid product that is resistant to breakage and is malleable enough to
allow adjustments and not alter the consistency of the material.
This product when properly cured and finished has proven to (be totally
inert) and will not subject the contacting tissue to be affected in any
way. This material over a period of time (normally 3 to 5 years) will
absorb body fluid that can become adverse to the tissues they contact.
This fluid can contain bacteria and acids that will cause irritations
and discomfort to the affected area. Replacements are necessary to correct
this so as to eliminate these symptoms, and regain a healthy ocular orbit.
Through proper notifications to our patients, this clinic advises these
patients to maintain proper hygiene and maintenance, to prevent any problems
that can arise from complacency and neglect . They are reminded that the
prosthesis must and I say must have their prosthesis cleaned –pumiced
and polished every 3 to 6 months to remove accumulated Plaque (protein
that builds up on the tissue bearing surfaces).This Plaque is the main
cause of irritation to the tissues, such as excessive excreta, soreness,
and possible infections.
My advice is that: “Proper Periodical Maintenance will save you a
lot of physical and mental discomfort”.
These products are not permanent, they must be replaced periodically.
