Calcium deposits on glyceryl methyl methacrylate and hydroxyethyl methacrylate contact lenses.
Five patients wore a hydroxyethyl methacrylate (HEMA) lens on one eye and a glyceryl methyl methylcrylate (GMA) lens on the other eye. The eye with the GMA lens remained comfortable longer than the other eye. The GMA lens is less likely to acquire calcium deposits and continues to be wearable longer than the HEMA lens.
