众所周知,OK镜(Orthokeratology)与RGP都属半硬性角膜接触镜,都是由同一种半硬性高透氧的隐形眼镜材料制成,但由于两者的设计和加工工艺的不同,使两者的适用范围及矫正效果有所不同。 角膜矫形接触镜即俗称OK镜,是一种特制的RGP半硬性角膜接触镜,OK镜是通过压力增加近视眼患者的角膜曲率,减少角膜屈光度,从而达到塑形角膜,提高视力,降低屈光度的目的,亦称“角膜塑形术”。OK镜的四弧设计包括:边弧、配适弧、反转弧、基弧。通过测定患者的角膜曲率、可见虹膜直径、屈光度、角膜地形
As we all know, Orthokeratology and RGP are semi-rigid contact lenses, are made of the same semi-rigid high oxygen permeability of contact lens material, but because of the difference between the two design and processing, so that both The scope of application and correction effect is different. Orthokeratology contact lens is commonly known as OK mirror, is a special RGP semi-rigid contact lens, OK mirror pressure is increased myopia in patients with corneal curvature, reducing the corneal refractive power, so as to achieve the shaping of the cornea, improve vision, reduce diopter Purpose, also known as “orthokeratology.” OK mirror four-arc design include: edge arc, with the arc, reverse arc, base arc. By measuring the patient’s corneal curvature, visible iris diameter, diopter, corneal topography
