Harold Ridley
Inventor of the intraocular lens in 1949
Even Sir Harold Ridley, the inventor of the implantable lens (IOL) in 1949, could never have imagined it: a faithful replacement of the human eye lens. After years of research and development, this is now a reality with the Lumina A-IOL. A unique high-tech application of a principle derived from optical physics allows the power of the lens to be adjusted for sharp vision both far and near.
A closer look at how the Lumina A-IOL works
The Lumina has two lens elements with specially manufactured surfaces that, by sliding over each other, produce a precise change in optical power. The two elements together form one lens with variable optical power for a full range of sharp vision.
Shifting optics
The Lumina is placed in the ciliary sulcus of the eye, behind the iris and in front of the lens capsule. The movement of the ciliary muscle, which controls focusing of the lens, is transmitted directly to the optical elements. When the ciliary muscle contracts or relaxes during the natural accommodation process, the lens elements shift to focus on the distance you are looking at.
Unique positioning
The Lumina is not placed back into the lens capsule of the removed cloudy lens, as is common with other lenses. The Lumina is placed just in front of it, in direct contact with the eye muscle. The Lumina is therefore not sensitive to the ever-present stiffening (fibrosis) of the lens capsule.
Stable and well-centred positioning
The Lumina is fitted so that it fits exactly in the ciliary sulcus. The haptics ensure stable and well-centred positioning. At rest, they do not exert any force on the ciliary tissue. The Lumina is inserted with a standard injector through a 2.4 – 2.8 mm incision.
