“The engineers at LensGen® have developed a biomimetic device with the inherent ability to change curvature similar to the natural human lens. In doing so the team at LensGen® has taken the next step forward in developing a superior and breakthrough technology in the surgical treatment of cataracts and presbyopia.”
This patented Technology is based on a monofocal lens that has a curvature changing fluid compartment that actively changes shape. A Modified Ring is placed into the capsule and the optic is then inserted separetely.
The Lumina AIOL (AkkoLens International, Breda, The Netherlands) consists of 2 optical elements, capable of moving one on top of the other, and is implanted in the ciliary sulcus The lens is manufactured with an acrylic hydrophilic polymer material. The optics provides a fixed optical power: the anterior element is designed to provide 5 D while the posterior provides between 10 to 25 D, depending on the correction needed for the patient after the lens removal. Each one of the optics has an internal aspheric surface where its power increases linearly when the lens moves. Therefore, when the eye accommodates and the ciliary muscle contracts, the optics of the lens change their longitudinal position, passing one over the other thereby resulting in an increase of the dioptric power of the lens, focusing the light for the near distance and providing accommodation to the patient.

The NuLens Dynacurve accommodative IOL (NuLens, Ltd., Herzliya Pituah, Israel) consists of: 1) polymethyl methacrylate (PMMA) haptics that are designed to be placed in the ciliary sulcus; 2) a PMMA anterior reference plane that provides distance vision correction; 3) a small chamber containing a solid silicone gel and 4) a posterior piston with an aperture in the center.
Such IOL prototypes, even with silicone gel of a relatively low refractive index (1.40), have been shown in a primate eye to deliver more than 40.00 D of accommodation using only 500 µm of vertical diaphragm displacement. No wonder the principle was evaluated clinically in AMD Patients, providing additional evidence regarding the Concept of possible extreme Accommodation. This Prototype of lens required a 9mm incision to be inserted in the sulcus/bag.
This is a multicomponent Lens system with two Optics, one of which can be easily exchanged, may work for pediatric cases and cases anticipated to have ametropia postop. Online calculator . French CE marked technology.
Posterior Optical Plate Aspheric Hydrophobic, Anterior Plate is Hydrophilic with Spherical Optic, Both are 5.7mm diameter. Both can be made clear or yellow colored.
The Sapphire IOL (Elenza) is electronically controlled, remotely programmable, customisable and utilises nanotechnology, artificial intelligence and advanced electronics to auto-adjust focus in response to pupillary changes. Speed and amplitude of pupillary responses are used to differentiate between light and accommodation. The power-cell requires recharging every three-to-four days, has hibernation mode and a fail-safe mechanism that converts it to monofocal status till recharged.
First announced in 2011, Many Prominent Ophthalmic Surgeons in the directory Board of Elenza, One of the two probable current “electronic IOL” .
