11. Patient with sagging right lower eyelid secondary to long-term wearing of an artificial eye without support from a motility/support peg. Hornblass's survey of over 5000 implant cases revealed a lower lid-malposition rate of 5 to 24% for silicone- and PMMA-type implants.

12. Female patient with a severely dropped socket. Note marked superior sulcus defect and severe laxity of the lower eyelid. Hornblass's survey of over 5000 implant cases revealed a lower lid-malposition rate of 5 to 24% for silicone- and PMMA-type implants.


13. Why old integrated implants failed

  • Violated basic surgical principle
  • Foreign material exposed
  • Wound could not re-epithelialize
  • Chronic infection-extrusion

14. Extruding Stone-Jordan implant. This complication was common with these partially buried and partially exposed implants.

15. Other types of the older integrated orbital implants. Clockwise from top left: Arruga implant, Moore implant, Cutler implant, Rosenthal implant.

16. Several different types of the old integrated implants which were partially buried and partially exposed. These implants were all developed by Stone.


17. Comparison of Implant weights

       HA     Silicone  Acrylic
16mm   2.1      3.4       3.4
20mm   2.8      4.8       4.9
22mm   4.7      6.3       6.5

18. Implant variations used over the years. The implant in the upper left is a hollow glass ball, as first used by Mules in 1884. Also shown are implants of gold, silicone, and acrylic in various shapes. Middle left: a Troutman implant containing a magnet to hold the artificial eye. Bottom right: the Bio-eye Hydroxyapatite Orbital Implant.


19. Advantages of the Bio-eye Hydroxyapatite Orbital Implant

  • Decreased migration
  • Decreased extrusion
  • Increased motility

20. Advantages of the Bio-eye Hydroxyapatite Orbital Implant

  • Support prosthesis via peg
  • Gives flexibility for fitting prosthesis to help (prevent) ptosis and superior sulcus deformity
