Ocular prostheses, which are custom made polymeric inserts that can be placed in anophtalmic sockets for cosmetic rehabilitation. Prosthetic eye wearers have reduced tear amount and they often experience dry eye symptoms. Most modern ocular prostheses are made of poly(methyl methacrylate) (PMMA), which is highly hydrophobic. Previous reseach has shown that improving the wettability of contact lens decreses its wearers discomfort by increasing lubrication. Therefore, hydrophilic modification of PMMA ocular prostheses might also improve patient discomfort by improving lubrication. We modified surfaces of PMMA ocular prostheses using poly(ethylene glycol) by two different methods. X-ray photoelectron spectroscopy, Scanning electron microscopy and atomic force microscopy was used and in vitro bacterial adhesion assessment was done. |
