    摘要: Disclosed herein is an implantable accommodative IOL device for insertion into an eye of a patient, comprising an active region and a passive region. The active region has a first thickness and first refractive index, and the active region comprises an electrically responsive optical lens having variable optical power. The passive region is disposed at a periphery of the active region, and the passive region has a second thickness and a second refractive index. The second refractive index is different than the first refractive index. Thus, the light beams passing through the active and passive regions have a phase difference, thereby providing an extended depth of field.

    摘要: A method for adjusting a light, adjustable lens m an optical system includes providing a light adjustable lens in an optical system; providing an ultraviolet light source to generate an ultraviolet light; aid irradiating die generated ultraviolet light with a light delivery system onto the light adjustable lens with a center wavelength and with a spatial irradiance profile to change a dioptric power of the light adjustable lens by changing a refraction of the light adjustable lens in a refraction-change zone, thereby causing a wavefront sag, defined as half of a product of the change of the dioptric power and the square of a radius of the refraction-change zone, to be within 10% of its maximum over an ultraviolet spectrum.

    摘要: A radiation-absorbing polymeric material comprises units of a polymerizable UV-absorbing compound, a violet light-absorbing compound, and a monomer, and is capable of absorbing UV radiation, at least about 90 percent of light having wavelength of 425 nm, less than about 50 percent of light having wavelength of 450 nm, and less than about 30 percent of light having wavelength of 475 nm. Ophthalmic devices, such as contact lenses, corneal rings, corneal inlays, keratoprostheses, and intraocular lenses, are made from such polymeric material.

    摘要: 一种植入性近视眼透镜片及其制备方法,所述镜片包括镜片主体(1)和沿镜片主体(1)边缘切割成型的数个片状的支撑臂(2),支撑臂(2)所在的平面与镜片主体(1)所在的平面夹角在10-20度之间,使得所述镜片的整体呈类球面,镜片主体(1)上设有透明光导区(3),镜片主体(1)和支撑臂(2)均为同一种亲水性聚丙烯酸酯材料所制成,该支撑臂(2)可以弯折,所述镜片植入人眼时会根据人眼轮廓自行调整支撑臂(2)的弯折角度,同一型号的所述镜片可以植入到不同大小的人眼中,由于支撑臂(2)与镜片主体(1)的连接处细而短,支撑臂(2)更容易弯折,自动调节所述镜片的尺寸使得所述镜片更贴合人眼,舒适性好,所述镜片材质折射率高,厚度低,亲水性聚丙烯酸酯材料富有弹性,方便植入人眼。
