Abstract
A sub-miniature optical system, based in principle on the Galilean telescope, for implantation in the eye following surgical removal of the natural lens. The system is made of methyl methacrylate and includes so-called air-lenses formed by bubbles defined by optically curved surfaces within the acrylic bodies. The positive element is surgically secured adjacent to the pupil. The negative element is mechanically connected to the positive element, and extends from it to within a few millimeters of the retina at the rear of the eye. The strength of the positive element is approximately 126 diopters for cases where the cornea is retained, and the strength of the negative element is about -2000 diopters, more or less, depending on its spacing from the positive element.
Claims8
An intraocular lens system comprising a body of a transparent material of a size and shape for implantation in the human eye and having front and rear surfaces, said body including a plurality of transparent bubbles completely enclosed therein and optically in tandem along the length thereof, the transverse internal surfaces of said body that define the front and rear boundaries of said bubbles being optically curved for refracting light passing lengthwise through said body and said bubbles between the front and rear surfaces of said body, the boundaries of a bubble adjacent to the front surface being curved for positive refraction of light and the boundaries of a bubble adjacent to the rear surface being curved for negative refraction.
An intraocular lens system comprising a body of a transparent material of a size and shape for implantation in the human eye and having front and rear surfaces, said body including two transparent bubbles completely enclosed therein and optically in tandem along the length thereof, the transverse internal surfaces of said body that define the front and rear boundaries of said bubbles being optically curved for refracting light passing lengthwise through said body and said bubbles between the front and rear surfaces of said body, the boundaries of the bubble adjacent to the front surface being curved for positive refraction of light and the boundaries of the bubble adjacent to the rear surface being curved for negative refraction.
