Hydroxyapatite was used in 56% of primary enucleations by ophthalmic plastic surgeons in 1992. The majority of these implants were wrapped in donor sclera. Hydroxyapatite had an acceptable complication rate, but more time is necessary to determine its long-term success rate.
4. Nunnery WR: Commentary. Ophthal Plast Reconstr Surg 1995, 11:87-88. This commentary notes the inherent bias of the survey by Hornblass et al. (Ophthal Plast Reconstr Surg 1995, 11:77-88), in that only a small percentage of surgeons polled responded and that the survey was subjective.

Ophthal Plast Reconstr Surg 1995, 11:95-99. Wrapping hydroxyapatite in a polyglactin 910 mesh is an alternative to wrapping with sciera. The implant goes into the socket readily, allows the muscles to be easily attached, and has no risk of disease transmission.

Placement of scleral windows posterior to the muscle insertion decreases the rate of exposure of hydroxyapatite implants after evisceration.

Magnetic resonance imaging can identify progression of fibrovascular ingrowth into hydroxyapatite orbital implants and guide surgical planning.

Ophthal Plast Reconstr Surg 1996, 12:127-130. Magnetic resonance imaging appears superior to bone scanning in determining the degree of fibrovascular ingrowth into hydroxyapatite implants.

11. Kaltreider SA, Newman SA: Prevention and management of complications associated with the hydroxyapatite implant. Ophthal Plast Reconstr Surg 1996, 12:18-31. Placing hydroxyapatite implants posteriorly and advancing extraocular muscles 5 mm from the apex of the implant decreased exposures. Most small exposures healed spontaneously, whereas larger exposures often required surgical intervention.

13. McNab A: Hydroxyapatite orbital implants: experience with 100 cases. Aust N Z J Ophthalmol 1995, 23:117-123. One hundred cases of hydroxyapatite implants showed an overall complication rate of 15%, and a significant increase in postoperative pain associated with hydroxyapatite implants was noted.
14. Remulla HD, Rubin PA, Shore JW, Sutula FC, Townsend DJ, Woog JJ, Jahrling KV: Complications of porous spherical orbital implants. Ophthalmology 1995, 102:586-593. Autologous wrapping of orbital implants decreased the rate of exposure. Small exposures responded well to conservative management.

A new implant composed of a silicone sphere with patches of porous silicone around an integrated peg and the insertion site of the extraocular muscles showed good conjunctival adherence and muscular adherence with minimal tissue breakdown.
21. Perry A: Review. Ophthal Plast Reconstruct Surg 1995, 11:200-208. Study by Jacob-LaBarre et al. (Ophthal Plast Reconstr Surg 1995, 11:200-208) had a high rate of peg malposition.
22. Goldberg RA: Who should have hydroxyapatite orbital implants? Arch Ophthalmol 1995, 113:566-567. There may be a higher complication rate with the use of hydroxyapatite implants. Hydroxyapatite implants should be used only in patients who are committed to go through all the stages needed for peg placement and fitting of a motility prosthesis.
23. Codère F: Hydroxyapatite implants: a rational approach. Can J Ophthalmol 1995, 30:235-236. Hydroxyapatite implants should be wrapped in some kind of covering, and patients should be well informed of the potential risks associated with hydroxyapatite implants.
