根据配戴硬性角膜接触镜的经验,提出配镜前应严格测量角膜曲率半径,并以其均值作为选用镜片曲率半径的标准。戴镜时泪液膜染色亦可作为选用镜片的参考指标。 According to the experience of wearing hard contact lenses, it is suggested that the curvature of the cornea should be strictly measured before the glasses and the average value of the curvature of the lenses should be taken as the standard. Teardrop membrane wear when wearing glasses can also be used as a reference indicator of the lens.
