Abstract

New medical products, materials and surgical procedures keep improving current health-care practices. Many of these innovations involve polymeric devices that must meet certain clinical and costs requirements. Chief among these pressures is the need for biocompatibility between the physiological environment and synthetic biomaterial surface. Carbon Film (CF) such as diamond-like, carbyne, carbyne-containing, carbon nanotubes; deposition for obtaining the materials with nanostructured surface (NSS) can improve synthetic material biocompatibility and biofunctionality.

The aim of our work was artificial iris creation and subsequent sufficient prosthetic replacement of a partial or complete loss of the natural iris diaphragm in eyes. For implantation artificial irises manufactured from polyethyleneterephtalate (PET), polytetrafluorethylene (PTFE) and polyvinilidenefluoride (PVDF) were used with their surface modification by CF deposition. Modification was carried out using CF deposition from directed ion-plasma flows of hydrocarbon vapors or by magnetron deposition.

Implanted iris prosthesis showed in all cases a stabile position. Iris prostheses which surface was modified by means of CF deposition after their implantations permitted the compensation of the native iris absence. NSS of artificial iris excluded fibrous tissue proliferation. Experimental eyes achieved the desired anatomic result.

Implantations of prosthetic iris devices manufactured from PET, PTFE, PVDF and covered by CF deposition showed the required results for eye diaphragm loss compensation. One of most convenient aspect of CF deposition technology is the potential for simultaneous surface modification and sterilization. Obligatory properties of artificial iris surface provided with CF deposition: the absence of toxicity, biocompatibility, and dispersed surface, certain adhesive and repelling for cells and the properties of chemical compounds can give a possibility of a successful application for this artificial substitute.
