Disfigured eye is not only a cosmetic problem rather it also has noticeable
impact on the social, personal and professional life of the patient as well as
their family. Innovations in Ocularistry and Ophthalmic plastics surgery can
helpin successful rehabilitation of these patients. The artificial eye is a
prosthesisthat has several significant functions. |
It is important to know that it does not restore sight,
but it does help to do the following:
1. Prevent remaining soft tissue from collapsing
2. Prevent eyelids and lashes from turning in
3. Facilitate the proper circulation of tears so they can
continue to do their job of cleaning and lubricating the socket and lids. |

We are concerned with the comfort as well as the cosmetic appearance
of the patient. Thus we make the prosthesis by taking custom impression
of eye socket individually fabricated to fit the size and shape of the eye. |

Fabrication of Custom Made Prosthetic:
Prosthetic eyes are made of an acrylic plastic material called poly methyl methacrylate (PMMA). It can be formed into any size and shape, It's durable, and is well-tolerated by the surrounding eye tissues. The prosthesis is made through the following series of steps:
 The process begins by taking an impression of the eye socket by silicon polymer to duplicate will fit into. The impression of the eye socket is used to make a wax model. Using the wax model, we determine the correct position of the iris and the extent which the will open.
- The wax model is then used to prepare a master mould which is filled with acrylic plastic to creat a cast of the prosthesis
- The iris button is hand painted from direct observation of the unaffected eye.
- This white acrylic is further colored and vessels are added to simulate a natural appearance. It is then covered with a clear plastic protective coating and is cured once more.
- The prosthesis is now ready after a high grade multi stage polishing to give it a perfectly smooth surface and wet-looking appearance.

Frequently Asked Questions: |
| |

 1) What are the indications of Artificial Eye?
Following cases are the indication for an artificial eye:
1. Absent eye following surgery (Anophthalmic socket)
2. Small disfigured eye following trauma (Phthisis bulbi)
3 Small eye since birth (Microphthalmos)
2) What can an artificial eye do for one-eyed patient?
It can eliminate physical discomfort caused by the disfigured eye and abnormally placed eyelids. A good matching artificial eye can lessen the psychological hurt of an eye loss and disfigured eye.
3)
What the difference between "stock" and "custom" eyes?
"Stock" or "ready-made" eyes are mass-produced. Since a "stock eye" is not made for any particular person, it doesn't fit and match any particular patient. A "custom" ocular prosthesis, on the other hand, is made by Ocularist to fit and match particular patient.
4) What is the advantage of "Custom-made" eyes over "stock" eyes?
Custom made eyes are more comfortable and have better resemblance to the other eye apart from the advantage of continuous wear and better motility of the prosthesis. Whereas the ready-made eye suffers from discharge, discomfort, poor matching,
less movement, restricted wearing period, lower lid sagging and contracted socket as a result in future.
5) Does this custom made artificial eye need daily removal and cleaning?
No. We make our artificial eyes by modified impression technique that eliminates discharge "collection in the socket. Therefore there is no need to remove it daily. It can be worn for months continuously. Patients can sleep without removing their artificial eye. |
