Embodiment 1

[0034] (1) Make the lens barrel and line it with an opaque sleeve: using hydrophobic acrylic material, a cylindrical tube with a height of 2mm and a diameter of 2mm is made by fine lathe, and lined with an opaque coating to prevent light scattering in the lens barrel. There are grooves near the mouth of the tube at the front and rear ends of the inner side for inlaying front and rear lenses; grooves are set at 0.5mm from the front end on the outer side for inlaying a brown light-shielding ring-double loop integrated structure.

[0035] (2) Making optical lenses: The front and rear lenses are made of hydrophobic acrylic material, the front mirror is a negative lens, the radius of curvature of the front surface is -1.628mm, the radius of curvature of the rear surface is 2.584mm, and the thickness is 1mm; the rear mirror is a positive lens , the radius of curvature of the front surface is 9.066mm, the radius of curvature of the rear surface is -2.175mm, and the thickness is 1.5mm;...

Abstract

The invention relates to production technology of an intraocular telescopic type artificial lens and discloses the intraocular telescopic type artificial lens and a production method thereof. The intraocular telescopic type artificial lens is applicable to the patient, with low vision, suffered from late macular degeneration and used for improve visual and living quality. The artificial lens comprises an optical system composed of a front lens and a rear lens which are spaced by air, a lens cone (4) and a structure integrating a brown shading ring (2) and double loops (1). The front lens, as a minus lens, and the rear lens, as a plus lens, are made of hydrophobic acrylate material, 3 mm in total thickness, 2 times in magnification, less 1 / 3 than the prior art in thickness, excellent in biocompatibility and imaging quality and high in intraocular stability. By the use of the intraocular telescopic type artificial lens, surgical incision is remarkably narrowed, surgical injury is reduced, the problem of excessive endothelial loss ratio is solved, and risk of serious intraoperative complications is decreased.

Description

technical field [0001] An intraocular telescopic intraocular lens and a preparation method thereof relate to the preparation technology of the intraocular telescopic intraocular lens, which is suitable for low-vision patients with advanced macular degeneration, so as to improve the visual quality and quality of life of the patients. Background technique [0002] The macular area of ​​the retina is located in the optical center of the human eye and is the projection point of the visual axis. Therefore, the target the eye is looking at is projected here, forming a central visual field of 15-20°. The healthy macular area is rich in cone cells responsible for fine vision. Therefore, this is where vision is most acute. The central vision detected by general vision tests is macular vision. Normally, vision is poorer in the retina beyond the macular area, which provides peripheral vision. [0003] However, when lesions occur in the macular area, the visual acuity comparison betwee...
