Occluar Prosthesis
Conditions
Brief summary
Different techniques of fabricating conventional custom-made ocular prosthesis were described. Traditional methods of custom fabricated ocular prosthesis had some limitations and take a long time, facial scanning and computed tomography will facilitate the full digital ocular prosthesis fabrication. Full digital ocular prosthesis is an innovated new technique to produce more accurate & more esthetic ocular prosthesis with less time consumed, however very few articles are available comparing between the full digital technique & the conventional one in manufacturing ocular prosthesis.
Interventions
OTHERDigital occluar prosthesis
Each patient will receive the full digital fabricated ocular prosthesis. DICOM data from the Computerized Tomography (CT) will be imported into Materializes Interactive Medical Image Control System (MIMICS) software++++ tool for visualizing and segmenting medical images (such as CT and MRI)
OTHERConventional occluar prosthesis
An accurate impression of the patient's eye socket will be obtained to prepare a suitable wax mod. The wax model will be flasked and processed into heat cured acrylic resin of the same colour of the sclera of the other healthy eye of the patient

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Motility of ocular prosthesis | Time of insertion | Using Matlab R2016b software+. For each patient, photos of different eye positions will be taken, namely, the frontal, upper, lower, left, and right viewing positions. |
| Change in patient satisfaction | Time of insertion and 3 months | Patient satisfaction will be evaluated by questionnaire based on the UK National Artificial Eye Questionnaire (NAEQ). The items that will be evaluated in the questionnaire include Time taken to adjust the prosthesis, Prosthesis cleaning frequency, Lubrication frequency, Comfort rating, satisfaction with prosthetic appearance, and satisfaction with prosthetic motility |
| change in microbial analysis | Time of insertion and 3 months | Patients will attend 2 visits (0,3 month), in which swab will be collected from the internal surface of the ocular prosthesis as well as from the anophthalmic cavit |
