Artificial
Eyes
The artificial eye is fitted to replace the lost volume of the socket and to restore natural appearance and movement. It is fitted after enucleation of the anterior segment of ocular evisceration. It is made of acrylic and it can withstand time, climate or any other element that could affect the eye. It also readily adapts itself to the temperature of the socket. The object of fitting an ocular prosthesis (artificial eye) is:

To maintain shape and the movement of the eyelid and for cosmetic purposes To retain the tone of facial muscles to prevent alterations of features To prevent foreign bodies from entering the ocular cavity To prevent accumulation of fluid in the cavity and to direct secretions to proper channels.

Available Sizes: Right and Left Eye; 20mm, 22mm, 24mm, 26mm and 28mm.

Cosmetic shell is used in case of disfigured eye only if there is no danger to the patient in the retention of the sightless eye. It is extensively used after evisceration. It is made of acrylic and it is lighter and thinner than artificial eye.

There are two types of cosmetic shells:
Cosmetic shell with transparent sclera: This is used in the absence of iris or lack of iris pigmentation when the sclera portion of the eye is not damaged and only the iris is disfigured.

Cosmetic shell with opaque sclera: This is used after evisceration when the sclera portion is damaged along with the iris portion.

Available Sizes: Universal; 22mm, 24mm, 26mm and 28mm.

Conformers are used after enucleation to conform to the conjunctival sac fornices. They should adhere closely to the socket contour and fill the depths of the fornices without stretching them. Easy closure of the eyelids after the conformer is slipped into place usually indicates proper fit. Most of the conformers have one, three and five drainage holes to allow mucoid discharge to escape and to facilitate the insertion of postoperative medication.

Uses of Conformers are as follows:
Conformers are used in patients with chemotic prolapsing conjunctiva They are used for prevention of the cul-de-sacs following chemical burns or traumatic avulsion of the conjunctiva They are also used after insertion of certain implants with a pressure dressing to lessen edema.

Available Sizes: URight and Left Conformer; 20mm, 22mm, 24mm, 26mm and 28mm.

Fornices open conformers are also known as Symblepharon rings.
They should be immediately inserted to prevent adhesions and shortening of the fornices and cul-de-sacs.
This conformer reduces scarring and keeps the lids away from an irritable eye.
This helps the patient feel more comfortable.

Available Sizes: Universal; 22mm, 24mm, 26mm and 28mm.

Spherical implant is positioned within tenon’s capsule without attachment to the orbital tissue. During the version movements, the fornices of the enucleated socket retracts and lengthens on the side towards the direction of the gaze because contraction of the muscles and Tenon’s layer occur on that side.

The objectives of the spherical implants are as follows:
It provides motility to the prosthesis.
It generally prevents cause of pressure necrosis

Available Sizes: 12, 14, 16, 17, 18, 19, 20, 21, 22, 23 & 24mm.

Castroveijo implant imparts motility to the prosthesis by acting as a smooth convex pivotal surface over which the artificial eye or cosmetic shell glides during shortening and lengthening of the fornices. Anteriorly, it has a central depression surrounded by four bridges. The four rectii muscles are accommodated in the tunnels situated directly beneath the bridge and the end of the opposed muscles are sewn so as to overlap each other. The implant is completely buried under the tenon’s capsule.

The advantages of Castroveijo implants are as follows:

It provides better motility and requires very little adjustments from the ocularists.
It provides support for the artificial eye and makes it look sulken.
It also serves to prevent bony deformity of the orbital wall.
It also helps to maintain the normal size of the socket.

Available Sizes: 13mm, 15mm and 17mm.

These are made specifically to protect the cornea while carrying out the procedure for eye lid surgeries. Corneal protectors are made up of PMMA material and are of universal shape i.e they can be used for right or left eye.

Available sizes: 22mm, 24mm, 26mm & 28mm

These sizers are used to estimate the depth and size of the cavity before any implant can be inserted.

Sizer box contains : 12mm, 14mm, 16mm, 18mm, 20mm, 22mm.

These are pumps which enable ease in handling of prosthesis or corneal shields while taking placing or removing them from the patient cavity. These are made of silicon material.
