Insertion of Ocular Prosthesis into
the Eye Cavity
It is easier to insert the ocular prosthesis with the fingers (for more control), than it is using the suction cup. Chances are the patient may blink or squeeze the lids during this insertion process, resulting in loss of suction and the possibility of dropping the prosthesis.
Cleansing of the Hands prior to Insertion
Please be advised that bacteria that frequently causes conjunctivitis and socket infections exists on the skin. We would therefore, recommend using a 'no more tears' baby shampoo for a thorough hand scrub with emphasis on the fingertips. This shampoo destroys bacteria and it has a neutral pH. The shampoo should also be applied with a warm wet facecloth to the ocular prosthesis. You may rub it vigorously with the facecloth to remove any dried protein deposits on its surface. Rinse well prior to insertion.
Insertion of the Ocular Prosthesis with Fingers
Step 1. Moisten prosthesis with water or any contact lens wetting solution for easier insertion.
Step 2. Hold the prosthesis by the outer edges with the thumb and forefinger. (The index finger will come into use in Step 4 & 5.) The black dot (left eye) or two dots (right eye) indicate the top of the prosthesis.
Step 3. Have the patient look downward and, at the same time, place your thumb or finger of your free hand on the upper eyelid and lashes. Pull the upper eyelid toward the eyebrow. This will create a large gap.
Step 4. Bring the prosthesis up past the lower lid and set it flush once it is partially past the lower eyelid and touching the orbital tissues. You may now place the index finger on the front of the prosthesis, allowing you to release the thumb and forefinger hold.
Step 5. The index finger will continue to push the prosthesis up and under the upper lid until it is completely in the socket.
Step 6. In one swift motion, release hold of the upper lid, and pull the lower lid downward, to allow the entire prosthesis to slip into the cavity.
