We make two types of prosthetic eyes made from acrylic material:
The artificial eye process is started two to three months following surgery, giving the socket sufficient time to heal. The client will usually be referred by an Ophthalmologist.
A minimum of four appointments are necessary to make an artificial eye usually in one week if suitable with the client. Occasionally extra appointments may be required.
The socket is first fitted with a conformer (a thin shell with holes) that gives the best shape to the lids. Mild discomfort may be felt during the impression process.
A syringe is filled with Alginate paste and the plastic tip inserted through a hole in the conformer. Pressure is applied to the top of the syringe until the paste fills the eye socket. The impression paste takes approximately 2 minutes to set.
The iris is hand painted to match the colour of the good eye.
A mould is made of the impression and a clear plastic shell produced. The shell is adjusted if necessary to match the shape and lid aperture of the good eye. The pupil is positioned.
The iris is trimmed and assembled with the scleral (white of the eye) plastic to form the eye.
The artificial eye is fitted and checked for comfort and pupil position. The sclera and blood vessels are matched with the good eye and any extra detail added to the iris.
Generally the eye is completed on the fourth day. The client will be shown cleaning techniques and how to insert and remove the artificial eye.
The client will be sent a recall letter after three months to review the fitting. A further recall letter will recommend an annual polish following this appointment.
Making of a Cosmetic Haptic Lens
The making of a cosmetic haptic lens follows the general format of the making of an artificial eye but requires trialing of a clear shell prior to making. It may be necessary to repeat this stage to ensure maximum comfort and build up wearing time.
In this process the iris may be painted directly on to the scleral shell.
This procedure is done in conjunction with an Optometrist in order to monitor the health and comfort of the eye.
