Abstract:
Hydroxyapatite, as a biologically active material, has the same structure and ingredients as the inorganic of hard tissue in human body, moreover, its biocompatibility and biological activity of interface are better than other biological materials. Hydroxyapatite has been widely used in anophthalmus reconstruction, orbital reconstruction, artificial cornea transplant and drug carrier. Pure hydroxyapatite has some defects such as brittleness, low-bending strength, the strength of anti-fatigue and anti-sabotage in the physical environment are not high. In order to overcome or reduce these shortcomings, porous hydroxyapatite and composite hydroxyapatite are made to extent the clinical application of hydroxyapatite. With a variety optimization of performance, process and preparation of the composite materials, the hydroxyapatite/polymer tissue engineering materials in ophthalmology will be further developed.
