Most modern ocular prostheses are made of poly (methyl methacrylate) (PMMA), which is highly hydrophobic. Prosthetic eye users have reduced tear amount, often resulting experience of dry eye symptoms. Previous research has shown that improving the hydrophilicity of contact lens increases lubrication which decreasing wearers discomfort. Therefore, hydrophilic modification of PMMA ocular prostheses might improve patient discomfort. We modified outmost surfaces of PMMA ocular prostheses using poly (ethylene glycol) by two different methods, “grafting to” and “grafting from”. X-ray photoelectron spectroscopy, Scanning electron microscopy and atomic force microscopy were applied and in vitro bacterial adhesion was tested. |
