Hydrophilic PEG grafting on PMMA ocular prostheses surface |
| 초록 |
The ocular prostheses made of poly (methyl methacrylate) (PMMA) is widely used for cosmetic rehabilitation. However, PMMA based ocular prostheses is highly hydrophobic and wearers have reduced tear amount often resulting experience of dry eye symptoms. Previous research about improving the hydrophilicity of contact lens increasing lubrication exist and therefore, hydrophilic surface modification of PMMA ocular prostheses might improve patient discomfort. We modified surfaces of PMMA ocular prostheses using poly (ethylene glycol) (PEG) by two different approaches, “grafting to” and “grafting from” for improving hydrophilicity. X-ray photoelectron spectroscopy, scanning electron microscopy and atomic force microscopy and in vitro bacterial adhesion analysis were utilized for demonstration of these approaches. |
