    • A multifocal ocular lens having a vision correction area which consists of a central, an intermediate, and an outer vision correction region having respective different values of an optical power, and which has an optical axis with which centers of the central and outer vision correction regions are aligned, the central and outer vision correction regions having respectively determined first and second mutually different values of the optical power, wherein the optical power of the intermediate region is represented by a combination of a first and a second quadratic curve connected to each other at a point of inflection which corresponds to a radial position of a boundary between the inner and outer sections, and which corresponds to a desired third value of the optical power between the first and second values, or the optical power of the intermediate region is represented by one polynomial equation whose degree is not smaller than 2 and continuously changes from the first value to the second value with an increase in a radial distance from the optical axis.

    • An eye bandage formed of a soft material and having a shape similar to a contact lens, the eye bandage being worn on an eye after an intraocular surgical operation of the eye, such that the eye bandage is held in contact with a cornea and a sclera of the eye so as to cover an incised portion of the sclera, the eye bandage comprising: a central portion which is to contact the cornea and which has a back surface having a profile following that of a front surface of the cornea; and a peripheral portion located radially outwardly of the central portion and having a thickness larger than that of the central portion and a diameter which is large enough to cover the incised portion of the sclera, the peripheral portion including at least a sclera-contacting portion that is to contact the sclera, the sclera-contacting portion having a back surface having a profile following a front surface of the sclera, so that the sclera-contacting portion is held in close contact with the sclera of the eye.
    • 由软质材料形成并且具有类似于隐形眼镜的形状的眼绷带,在眼睛的眼内手术操作之后眼绷带佩戴在眼睛上,使得眼睑保持与角膜和巩膜接触 的眼睛,以覆盖巩膜的切口部分,所述眼绷带包括:与角膜接触的中心部分,其具有与角膜前表面相似的轮廓的后表面; 以及周边部分,位于中心部分的径向外侧并且具有比中心部分的厚度大的厚度和足够大以覆盖巩膜切口部分的直径,所述周边部分至少包括巩膜接触部分, 与巩膜接触,巩膜接触部分具有后表面,具有跟随巩膜前表面的轮廓,使得巩膜接触部分保持与眼睛的巩膜紧密接触。
