A round-up of the latest ophthalmic products

Compact and portable phaco

Being only 5 kg in weight, the CataRhex 3 can fit into a pilot case and be suspended on an IV pole for ease of transportation and mobility when in use. With its embedded technology the device does not require a Windows or PC operating system and an integrated USB interface enables updates at any time. The device can also be individually programmed for up to 20 different surgeons.

Glaucoma module edition

The software is reported to offer comprehensive analyses for optic nerve head (ONH), retinal nerve fibre layer (RNFL) and posterior pole asymmetry. Including a new Anatomic Positioning System (APS) for the SPECTRALIS, the company states that all OCT-scans are accurately placed relative to the position of the fovea and Bruch's Membrane opening (BMO), which are used as anatomical landmarks of the eye.

Additionally, the company reported that the new optic nerve head assessment is based on the research performed by Professor Chauhan's group and Professor Burgoyne's group. Using the SPECTRALIS SD-OCT, the researchers revealed the importance of making an anatomically and geometrically accurate neuroretinal rim measurement using BMO rather than the clinical disc margin.

Therefore, the new software measures from the BMO to the nearest point at the internal limiting membrane (ILM), quantifying the minimum cross section of the nerve fibres exiting the eye. This means that the BMO-based minimum rim width (BMO-MRW) can be assessed and regionalized relative to the axis between BMO and the fovea for accurate analyses.

Multifocal IOL

This lens features additive paraxial asphericity (APA) to enhance far and near focus zones for better depth of focus and a balanced vision at all distances, offer good visual performance in intermediate vision field through adapted zone focusing and interpret neuronal images easily as a result of intelligent focal modulation for all light conditions.

Additionally, this new lens features surface design optimization (SDO). The company reports that this feature enables higher pupil independence and better reading through a new surface design of the near vision segment, light efficiency of greater than 95% through improved SML production technology and significantly reduced photopic phenomena by homogeneous peripheral transition zone.

Transitional conic toric IOL

The company states that the Transitional Conic Toric Radius blends into the aspheric surface of all meridians leading to a broader toric surface. This ensures alignment with the patient's astigmatism and extends the depth of vision.

Furthermore, it is reported that the lens has a proven stability with 3.1° of average rotation over 4–6 months.

All customers will receive an OPHTEC Premium IOL Set, comprising a 2.2 mm incision disposable injector/cartridge system and a pre-loaded capsular tension ring, when buying the lens.
