Abstract

 This article describes HSGS method for determination of  Methylmethacrylate (MMA) in polymeric matrixes of  Polymethylmetacrylate (PMMA) in rigid contact lenses for correction of refractive errors. The non-polymerized MMA has to be kept under certain values determined by specific regulations because it can restrict oxygen diffusion through the contact lens and cause ocular complications such as hypoxia and corneal oedema.
