材料降解的情形仍然發生，尤其於樣品配方比(PEGDA:P407DA:mPDMS )8:1:1 之 水膠在第二個月時有被大鼠組織吸收的情況產生，而第三個月所有製成之樣品水
體製成之水膠的效果較好，此外雖大部分的性質有所改善，但於動物實驗之中對 照 PEGDA 水膠卻仍舊沒有細胞長入水膠，此結果應為水膠材料的特性所致。
目前由 FDA 所通過之人工角膜，以剛性合成材料(波士頓人工角膜，Boston Kpro)及軟性合成水膠(AlphaCor)為主，並由臨床研究及個案報告之結果比較，以 剛性合成材料的成果較佳而軟性的合成水膠較差，因此在本研究中，吾人使用不 同的材料及配方，以較為簡單且低溫之光交聯方法合成水膠，以期開發能夠大量 生產的角膜襯裙材料，供軟性水膠製成之人工角膜的改善使用。
