“…Custom conformer fabrication may be indicated when the definitive ocular prosthesis will be delayed due to slow patient recovery, medical complications or patient preference. 9 The effectiveness of various impression techniques depends on various factors such as the type of patient, space for the prosthesis, available tools and materials, operator experiences and patient psychology. 10 Impression techniques are performed very well and satisfactorily in the rehabilitation of anophthalmic patients.…”

The cosmetic disfigurements which arise due to loss of orbital volume after enucleation of an eye include enophthalmus, superior sulcus deformity, upper eyelid ptosis, and lower eyelid laxity. The treatment can be either conservative or surgical. For patients who does not want to undergo further surgical procedures, the conservative treatment is simple, non-invasive, and appropriate. This case report describes modified impression tray and iris positioning technique of post enucleation socket syndrome to achieve aesthetics and function. A 65-year-old male patient reported to the Dental Hospital Universitas Sumatera Utara with the chief complaint of facial disfigurement due to loss of the right eye. Patient had enucleation 6 months ago and using conformer after surgery. The diagnosis was post enucleation socket syndrome. Clear acrylic sclera as a tray without handgrip will precisely records of the palpebre con- vexity and specified socket. The use of eyebrow ruler helps accurately determine the symmetrical iris position com- pared to only visually determining which is subjective with the possibility of interobserver errors. It was concluded that clear acrylic sclera as a tray and eyebrow ruler to determine the position of iris resulting in patient satisfaction due to aesthetics and function.

Primary goal in successful rehabilitation of a patient with ocular defect is to fabricate a well-fitted ocular prosthesis that mimics the original shape and position of the residual anatomical structures and restores volume of the defective socket. Adequate palpebral opening, iris-scleral visibility, color and size of iris, centering of pupil, shade of sclera, proper fixation of gaze and characterization of prosthesis are the key aspects that deserve meticulous attention. Fixation of gaze and selection of iris size can be achieved by various techniques. Four techniques involving usage of millimeter markings and numerical values with armamentarium such as spectacles with graphic grid, cassette holder with grid, modified graphic grid ruler, RS-3 Ophthalmic pupil distance meter coupled with digital imaging technique for iris selection are highlighted through these case series.

“…1 Surgical management of eye removal can be classified into three categories: evisceration, enucleation, and exenteration. 2,3 Exenteration is the removal of the entire contents of the orbit, including the extraocular muscle. Enucleation is the surgical removal of the entire eye opthalm and part of the optic nerve from the orbit.…”

Ocular prosthesis for post evisceration socket often has feeble adaptation to the surrounding tissue due to high sensi-tivity. Excessive pressure given by impression technique would lead to irritably intaglio and bulky palpebral contour of the prosthesis. This article describes a modified method of functional impression which made it easier not only to record the tissue bed surface of the defect but also to get the right contour of the palpebral surface at the same time. A 60-year-old male came to Dental Hospital Universitas Sumatera Utara with evisceration defect as a result of traumatic injury 40 years ago. He complained a facial disfigurement that made him formidable with social interacti-on. Pressureless impression combined with calibrated tray was planned for the patient. Light body PVS material was injected into the socket under slight pressure and the conformer made from visible light cure acrylic resin was in position as a tray. Vertical and horizontal lines marked in the conformer calibrate with the facial marking as a gui-dance for 3-D position. The method is intended to get the fast, accurate position offering the patient ocular prosthesis with great comfort as well as to provide facial contours that improve the patient's psychological and physical outlook.
