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.
五名患者一只眼睛佩戴甲基丙烯酸羟乙酯(HEMA)镜片,另一只眼睛佩戴甲基丙烯酸甘油酯(GMA)镜片。佩戴GMA镜片的眼睛比另一只眼睛保持舒适的时间更长。GMA镜片比HEMA镜片更不容易形成钙沉积物,并且可佩戴的时间更长。
