6. Types of Eye prostheses
Conformers
Ocular prosthesis
Orbital Prosthesis

7. Patient evaluation
• For ocular defects
– Prognosis estimation
– Physical evaluation
– Muscular evaluation
– Desires and expectations of the patient
– Counselling the patient
• For orbital defects
– Pre-operative evaluation better than post-operative
– CT, MRI, FNAC useful.

8. Treatment planning
• Patient centered model
• Multidisciplinary
• Initial visit – determine treatment needs and confirm them with
patient
• Discuss these needs with team members – process and outcome
• All the pre-requisites should be planned
• Patient confirms regarding the procedure after consultation
• Signed consent
• Start treatment

9. Treatment planning - steps
• Planning Retention
• Moulage impression and working cast fabriction
• Pattern fabrication and try-in
• Craniofacial implants placement followed by impression
• Cast modification
• Pattern try-in
• Processing
• Insertion and maintenance

10. Methods of retention
• Extra-ocular muscles
• Adhesives
• Mechanical : Eyeglasses/Spectacles
• Magnets
• Implants: Bar and clip attachments or magnetic attachments

23. Procedure

24. Procedure

25. Recent trend – Bionic Eye

26. Maintenence
• Adjustment to the prosthesis
• Period of wear
• Removal and replacement
• Cleaning
• Recall
G. R. Parr, B. M. Goldman, and A. 0. Rahn. Postinsertion care of the ocular prosthesis. J Prosthet Dent 1983; 49(2); 220-224

27. Complications
• Tissue irritation
• Inadequate peri-orbital support
• Recurrence of tumor
• Implant exposure
• Conjunctival thinning
• Discharge
• Pyogenic granuloma formation (excess healing tissue formation),
• Rarely persistent pain or discomfort

28. Conclusion
To meet challenges and surpass them is the basic means survival of
the fittest.
With efficiency and uncompromising efforts, this task becomes
easier.
