Purpose: To reduce antigenicity of allografts and stimulate their replacement by natural recipient tissues., Methods: Experimental allotransplantation of different tissues (fascias, tendons, derma, fat, etc.) with histological, histochemical, electron microscopical, electron histochemical examination 3, 5, 7, 14, 21, 30, 60, 120, 180 and 360 days postoperatively., Results: Allografts of different tissues with glucosaminoglycans extracted from collagen fibers have low antigenicity and can be replaced by natural tissues. Allografts with these properties were named 'Alloplant'., Conclusions: Alloplant biomaterials can selectively stimulate natural tissue regeneration. Hence, Alloplant biomaterials can be utilized in surgery for the restoration of different tissues.

The introduction and use of newer surgical materials, better surgical instruments, finer suture materials, and improved optical equipment have allowed us to advance certain techniques in ophthalmic surgery and ophthalmic plastic surgery. In oculoplastic surgery, fascia lata and sclera are but a few of these materials used with greater frequency. In this paper, a number of techniques are described depicting the use of fascia lata and sclera. A histologic study of these materials after variable periods of implantation is presented.
