ZABBYS HYDROXYAPETITE EYE SPHERE SIZE 16MM ZHAE-16 INTRODUCTION every human being deserves good look. After evisceration the sclera and muscles contract and shrink. The contour of eye is lost. The artificial eye prosthesis, worn later on, will always look artificial due to lack of eye movements. If evisceration /enucleation has been done in childhood the eye socket may not develop to full size and a bony deformity may occur. The purpose of Z-Eye is to maintain contour of eyeball, maintain the eye movements, provide a base for prosthesis, and maintain shape of eye socket and to prevent bony deformity. Lastly, but not the least, to give full self-confidence to the patient. It gives excellent cosmetic results. The artificial eye prosthesis, to be worn later on, will look natural due to good eye contour and almost full eye movements. DESCRIPTION OF Z-EYE Z-Eye is made of natural Calcium Hydroxyapatite .

OPERATIVE PROCEDURE The implantation of Z-Eye may be accomplished through variety of procedures. The choice depends upon the training of surgeon, customs in that hospital, country. Therefore the surgeon is best advised to use method, which his/her own practice and training dictate to be best for the patient. Following procedure is to act as guideline only. Insertion of Z-Eye is done after completion of evisceration of eye and before closure of sclera and conjunctiva. Evisceration is done on standard lines. A proper size of Z-Eye is selected. The G-Eye is inserted in the scleral cup. The edges of sclera are sutured in the lateral line with interrupted vertical inverting mattress sutures. To avoid "dog ear" projections of sclera at each end of the sutured line, a triangle of sclera is excised from each end with the bases towards the center. An alternative procedure is to make from the limbus four radial scleral incisions about 5 mm long at 1.30,4.30, 7.30 and 10.30 o'clock when Z-Eye is in place, two chromic catgut mattress sutures approximate the medial and lateral scleral flaps and two chromic catgut sutures join the upper and lower flaps. In case of enucleation, cadaveric preserved sclera is used. Z-Eye is put into the pouch of sclera. The pouch is properly stitched from all sides. It is placed inside the eye socket. Four recti are stitched on four side with scleral pouch. Tenon's capsule is sewn over this with horizontal line of interrupted 1 metric (6/0) chromic catgut sutures and the conjunctiva with continuous key pattern suture of 0.5 metric (8/0) chromic catgut. POSTOPERATIVE MANAGEMENT The patient may be mobilized early. On the first postoperative day the conjunctival sac is irrigated. The firm pressure dressing is maintained for 2 days, when the socket is dressed. This may be re applied with daily dressings until the fifth day. An acrylic shell may be placed in the conjunctival sac and a convex black eye shade, lined with sheet of lint, the smooth side opposed to the socket, is applied. The acrylic shell, approximately the shape and size of prostheses to be fitted later, helps to reduce the edema of the conjunctiva and to maintain the appropriate size and shape of the socket. A prosthesis is fitted in the third or fourth week of operation. Pain may be severe for two three days and chemosis may take up to three weeks to subside.
