Ocular Prosthesis

At Imperial Healthcare institute, we offer Artificial Eye and low vision treatment. We strive to provide you with the best prosthesis available in the Middle East. The Specialist carefully takes precise 3 dimensional measurements of the cavity with all the real eye details to reach a fully condensed cavity. With respect to Low Vision, The clinic have a leading doctor in this domain who uses a wide range of magnifying instruments that help our patients proceed with their normal life, peace of mind, and of course visual independence.

Who Needs Ocular Prosthesis

The loss of an eye or any part of the face in most cases will cause extreme apprehension and disbelief to the person involved. However, with the prosthetic eye techniques and material available today, these problems are readily solved both physically and physiologically.

There are many reasons that lead to the loss or shrinkage of the eye causing a facial deformation. This deformation cannot be fixed except with an ocular prosthesis.

These causes are:

  1. Congenital disorders giving a monophthalmic (with one eye) new born
  2. Incidents, car accidents, wars, fire-works
  3. Cancerous diseases
  4. Painful and chronic conditions that cannot be cured
  5. Intraocular inflammations which lead to the evisceration of the affected eye to save the other one
  6. Other diseases…

Definition of the ocular evisceration:

Ocular Prosthesis

The decision of the ocular evisceration causes a patient‘s frustration because the operation, in his opinion, will make a hole in his face. This surgery consists of a corneal ablation and a removal of the intraocular content only. The ocular muscles and the sclera remain intact. Then, the ophthalmologist inserts the suitable intraocular ball to maintain the ocular volume. There are many types of intraocular balls. The most recent one is the hydroxyapatite in which the blood vessels infiltrate prohibiting its rejection and providing a better movement of the prosthesis.

Techniques

The Ocular Prosthesis process is achieved within the following:

  1. Silicon Injection in the cavity to create a full 3 dimensional measurement
  2. High Resolution Picture of the Normal eye to identify the color of the sclera, the quantity of the vessels, and the color of the iris
  3. The doctor takes the diameter of the Iris and the pupil
  4. Then the artificial eye gets sent to be manufactured in a specialist lab using ocular P.M.M.A. material to reduce allergic reactions and prevent any unwanted secretions
  5. The material used is very bold that it can neither be broken nor scratched

First, the specialist measures the ocular cavity by injecting silicone liquid under the eyelids to determine the size of the prosthesis. This procedure prevents the tears accumulation and secretions behind the artificial eye. This technique is not only painless but also ensures a movement of the prosthesis almost similar to that of the normal eye. The color of the prosthesis is designed according to that of the intact eye captured by computerized systems of high resolution while taking into consideration the whiteness of the sclera and the density of blood vessels. Once all the necessary details are collected, the artificial eye is made of polymethylmetacrylate. This material is also used in the manufacturing of hard contact lenses. It is very light, unbreakable, scratch resistant and hypo allergic.

How to insert the ocular prosthesis?

In the majority of cases, the patient does not have to remove or clean his ocular prosthesis such he won’t watch himself without it.

Ocular prosthesis insertion:

The ocular prosthesis is put under the upper eyelid, and then the lower eyelid is retracted downward to completely insert it.

Ocular prosthesis removal:

The tweezers are positioned centrally to release the prosthesis from down ward, and then the lens is pulled forward to pop out.

The hygiene is very important upon the insertion or the removal of the prosthesis

The patient is recommended to clean the prosthesis with the disinfecting solution used for contact lenses, and to use a lubricant (artificial tears eye drops) when required to facilitate the movement of the lens especially in dry climates.

In case of excessive dryness, the patient should consult his ophthalmologist.

Ocular prosthesis for children:

Ocular prosthesis for children: Children require a special care, the patient should be followed up each six months in order to compare and adjust the size of the prosthesis to assure a symmetrical growth of both globes.
