Objective To explore the preparation method of rapamycin(RAPA)liposome eye drops and its effect on corneal neovascularization(CNV)in rats. Methods Rapamycin liposome eye drops were prepared by thin film hydration.The major factors on the preparation of RAPA liposome were studied by orthogonal design.The ideal prescription was then screened out.Using transmission electron microscope(TEM)to observe the morphology of liposome,and the particle size was measured by laser light scattering method.This study consis...
