A 41-year-old female was referred to Department of Prosthetic Dentistry for the Ophthalmology Department. On history it was found that the patient was suffering from malignant melanoma of the right eye and the eye had to be enucleated. So surgery was done and the eye was enucleated [Figure - 1]. On examination of the patient 15 days after the surgery, it was decided that a custom-made ocular prosthesis would be the best to meet the needs of the patient as the extra effort that is put into fabrication of a custom-made prostheses would enhance the esthetics and functional results rather than a stock ocular prosthesis.
Disinfect and lightly lubricate the patient’s existing prosthesis or conformer.
Fill a medicine cup with quick set stone and invest the tissue side of the prosthesis to the height of contour 3. When set, notch the edges of the stone cast. Mix a small amount of PVS putty and adapt it over the top of the prosthesis and into the notched indices
Remove the putty cope, and cut a large, beveled sprue hole into its center and a small vent to the side.
Remove the prosthesis from the mold, lubricate the stone surface (Liquid Tin Foil Substitute; Robert B. Scott, Inc, Tampa, FL), and replace the putty cope.
Mix chemical-cure polymethylmethacrylate (Great Lakes Co, Chicago, IL), and pour it into the mold
Remove the acrylic resin tray, trim and thin as needed. Perforate the approximate pupil location with a 3- to 4-mm diameter hole. Place multiple perforations over the remainder of the surface.Smooth and polish the custom tray
To fabricate the injection tube, unscrew the tip of a 5-mL plastic syringe (Becton Dickinson and Co, Franklin Lakes, NJ), and cut approximately 7 mm from the end (Fig 4). Roughen the sides of the tip and wedge it into the pupil perforation hole. Secure it with cyanoacrylate resin
Clean and disinfect the custom tray. Try in the tray and check for overextension and proper orientation. Attach the barrel of the 5-mL syringe to the injection tube. Orient the tube with the numbers facing upward . Mix 3 teaspoons water to 1 tablespoon ophthalmic alginate impression material (Robert B. Scott, Inc), and back load the syringe. Insert the plunger, seat the tray, and inject the alginate,the patient stares straight ahead until the material is set. After the alginate impression material has set, remove and check the mpression for acceptability.
A wax trial ocular prosthesis (blank) can be made chairside by using the “double alginate technique Suspend the impression in a small cup using a clothespin Pour a new mix of irreversible hydrocolloid into the cup, surrounding the impression. When set, remove the alginate mold with impression from the cup. Partially section the alginate mold, spread it, and retrieve the original impression. The different mixes of alginate will not adhere to each other
The second alginate impression becomes a mold to form the wax blank. Replace the alginate mold in the cup, and pour ivory wax
A prefabricated iris button, whose shade matched with the contra lateral eye, was selected. The position of iris was determined with help of landmarks making the patient look straight. Later the final try in was done keeping the iris in its defined position
Try in the wax trial prosthesis. Assess fit, contour, and comfort. Add the iris button to the pattern, then process.
Try in of the wax pattern was done. Petroleum jelly may be applied in the tissue surface of the wax pattern to avoid irritation to the tissues. The wax pattern was checked for the size support from tissue simulation of eye movement and eyelid coverage.
Flasking was done taking care that the iris is secured to one counter of the flask and remaining part in the other portion of flask. Packing was done with the selected heat cure tooth colored acrylic with small red colour silk thread, which may simulate the blood vessels. Slow curing cycle was carried out for acrylisation.
After you receive your new artificial eye (ocular prosthesis), there are a few things you should know about caring for and handling it properly:
Enuclene is a mild decongestant and lubricant that can help patients with excessive secretions. It may be obtained without a prescription at a pharmacy, from your ocularist, or ordered through this website. Sil-ophtho is pure lubricating silicone oil that may be applied directly to the prosthesis prior to insertion or while it is being worn. Sil-ophtho will provide hours of comfort during those times when the humidity is excessively low. It is available in a light and heavy viscosity. Sil-ophtho is usually found only in an ocularist&apos;s office.

Ocular prosthesis is a modality of facial
prosthesis that aims to repair total or partial
ocular bulb losses or deformities.
The main goals are toRestore facial esthetics,
Prevent eyelid collapse and deformity,
Protect the socket against injuries caused by
foreign bodies, dust and smoke,
Re-establish the correct route of the
lachrymal secretion to prevent accumulation
in the cavity, and
Preserve muscular tonus to avoid antisymmetrical alterations.
The eye was a symbol of life
to the ancient world,
particularly in Egypt, where
bronze and precious stone
eyes were placed on the
The Romans decorated
statues with artificial eyes
made of silver.
Ambrose Paré (1510-1590), a famous
French surgeon, was the first to describe
the use of artificial eyes to fit an eye socket.
These pieces were made of gold and silver.
Enamel prostheses (1820s1890s) were attractive but were
expensive and not very durable.
The introduction of cryolite
glass, made of arsenic oxide
and cryolite from sodiumaluminum fluoride (Na6A2F12),
produced a grayish-white color
suitable for a prosthetic eye.
German craftsmen are credited
with this invention in 1835.
To make these glass eyes, a tube of glass
was heated on one end until the form of a
ball was obtained. Various colors of glass
were used like paintbrushes to imitate the
natural color of the eye
The glass art form flourished in France
and Germany where fabricating secrets
were handed down from one generation
to the next.
The town of Lausche, Germany, had a
particularly rich history in both decorative
(doll eyes, Christmas ornaments) and
In the 19th century, German craftsmen
("ocularists") began to tour the United
States and other parts of the world,
fabricated eyes and fit them to patients.
Stock eyes (or pre-made
eyes) were also utilized.
An "eye doctor" might
keep hundreds of glass
stock eyes in cabinets, and
would fit patients with the
best eye right out of the
In the United States, eyes continued to be
made of glass until the onset of World War
II, when German goods were limited and
German glass blowers no longer toured the
The United States military, along with a
few private practitioners, developed a
technique of fabricating prostheses using
oil pigments and plastics. Since World War
II, plastic has become the preferred
material for the artificial eye in the United
By the mid-1940s, glass
eyes were being replaced
by plastic counterparts.
In Virginia, this was led
by Joseph Galeski
(of Richmond, Virginia),
Although American Optical
and several military
hospitals started to
experiment and dispense
plastic artificial eyes.
An ocular implant
replaces the lost volume
of the natural eye. The
first account of placing
an implant in the socket,
was in 1841.
Implants have been
made of many different
materials, shapes, and
types throughout the
years. It also helps the
artificial eye to have
some degree of
A custom ocular prosthesis
– Improved adaptation to underlying tissues,
– Increased mobility of the prosthesis,
– Improved facial contours, and
– Enhanced esthetics gained from control
over the size of the iris, color of the iris
– It is more expensive than a stock
prosthesis, and several steps are required
for its fabrication
1. Never clean or soak your artificial eye in
rubbing alcohol because it will crack and
destroy the ocular prosthesis.
2. Remove the ocular prosthesis only as
necessary. Too much handling can cause
socket irritation and result in excessive
3. If you remove your ocular prosthesis, be
sure to store it in water or soft contact
lens saline solution. This will keep deposits
from drying on the surface.
4.To clean your prosthesis, use an
antibacterial soap. Wash the eye between
5.If you wish to or need to rinse out the
socket, use sterile saline with bulb
6.Any eye drops can be used with the
artificial eye in place.
7.Visit at least once a year or more often
to have your ocular prosthesis checked,
cleaned and polished.
The use of custom-made ocular prosthesis
has been a boon to the patients. The
esthetic and functional outcome of the
prosthesis was far better then the stock
Although the patient cannot see with this
prosthesis, it has definitely restored his
self-esteem and allowed him to confidently
face the world rather than hiding behind
