角膜接触镜是一种直接带在角膜上的新型眼镜。近几年,国内一些单位相继研制成功这种眼镜,予计将很快普及全国。由于角膜接触镜直接配带在角膜上,它的曲率必需与角膜曲率相吻合,否则会引起眼睛的不适感。因此,在配带前必须准确地测量角膜曲率半径。此外,对于角膜病患的诊断、治疗、手术也都需要测量角膜曲率和散光。这就要求有一种专门用来测量角膜曲率半径和散光的仪器——角膜曲率检测仪。
The contact lens is a new type of lens that is directly attached to the cornea. In recent years, some domestic units have succeeded in developing such glasses, which are expected to popularize the country soon. Because the contact lens is directly attached to the cornea, its curvature must be consistent with the corneal curvature, otherwise it will cause eye discomfort. Therefore, the curvature of the cornea must be accurately measured before it is worn. In addition, corneal curvature and astigmatism are also required for the diagnosis, treatment, and surgery of corneal disease. This requires a special instrument used to measure the corneal radius of curvature and astigmatism - corneal curvature detector.
