Abstract
An eye lens having a front lens element and a rear lens element, which each have a positive optical power and an optical region, and an intermediate element, which is connected to the lens elements outside the optical regions so that the lens elements and the intermediate element form a cavity. The eye lens allows the width of an access incision necessary for implantation to be reduced. The eye lens includes the lens elements and the intermediate element that are shaped such that, in the implanted state, a distance between the front lens element and the rear lens element is fixed and the cavity has an opening which allows liquid to flow into the cavity. Embodiments of the invention include a method for producing such an eye lens and a method for implantation.
Claims15
A non-accommodating intraocular lens (IOL) that is implantable in an eye, comprising:
- a front lens element having a first optical region and a first positive refractive power;
- a back lens element having a second optical region and a second positive refractive power;
- an intermediate element,
- wherein the intermediate element is connected to the front lens element outside of the first optical region and wherein the intermediate element is connected to the back lens element outside of the second optical region, so that the front lens element, the back lens element, and the intermediate element together form a cavity,
- wherein the intermediate element fixedly spaces the front lens element from the back lens element when the eye lens is implanted,
- wherein an opening extends into the cavity to allow liquid to flow into the cavity,
- wherein a thickness of the eye lens measured as a maximum extent along a z axis is less than 3.0 mm, and
- wherein each of the first positive refractive power and the second positive refractive power are fixed.
