Femto-Masking

Femto-Masking by ROWIAK is a newly developed procedure that can improve near and intermediate vision of monofocal intraocular lenses dramatically - non-invasive, fast, easy to use and with an immediate wow effect for patients. The procedure can be used for new implants as well as for implants inserted up to three years ago.

There is a gigantic market for Intraocular Lenses.

Anyone who needs an artificial lens because of cataract disease has to live with the fact that they can no longer achieve the visual comfort they had before the disease. read more: Despite constant development, the currently available artificial lenses (intraocular lenses IOL) do not manage to produce sharp images at all distances without limitations, as the human lens is able to do. Nevertheless, more than 30 million artificial lenses are implanted worldwide every year to prevent cataract patients from going blind.

Depending on the country, about 95% of these are so-called monofocal lenses, which usually provide sharp vision at a distance. Patients need glasses for the near and intermediate range, for example for reading or working at the computer.

Current solutions are not satisfying.

Two segments of artificial lenses can be distinguished: standard and premium lenses. read more: Monofocal lenses only have one focus, so they only achieve sharp vision at a certain distance and the patient needs additional glasses.

Multifocal lenses produce different focal points at different distances. Now the brain has to compose a sharp image from the different images. The brain adapts to this "new vision" in a few weeks, but it can also underdevelop, which the patient has to accept. Patients often lose sensitivity to contrast and blinding phenomena additionally impair visual performance. During the healing process, sometimes the capsular bag in which the lens is located shrinks. This subsequent decentration. Also an imprecise placement during the operation is another risk factor. Furthermore, multifocal lenses are significantly more expensive for the patient than the monofocal solution, which is why these still make up the largest share.

In the past, numerous ideas have been put forward to circumvent or remedy the limitations of otherwise well-functioning monofocal lenses. Monovision (implants one lens for near and far) may work with a maximum difference of 1.5 diopters, which is far too little. Procedures like the Laser Refraction Method (Refractive Corneal Laser Surgery), or Corneal Inlays (most of which have now been withdrawn from the market) try to produce multifocality but fail because of similar side effects to multifocal lenses and require an additional surgical intervention with the corresponding wound healing risks.

A kind of intermediate solution are the so-called EDoF-IOL (Extended Depth of Focus), which have less blurred areas than monofocal lenses and produce fewer side effects such as glare and halos. But here, too, unrestricted sharp vision is not possible without glasses.

The pinhole effect for the eye has been demonstrated to work.

Recently implants have been on the market that use an optical principle from photography. They achieve significantly more sharpness in near and intermediate vision. read more: In photography, a hole of adjustable size is inserted in front of the camera lens with the help of the so-called aperture, thus adjusting the depth of field of the image. A smaller aperture creates a depth of field over several distance levels.

In fact, this principle also works for the human eye. The mode of action has already been clinically evaluated and approved using two implants (KAMRA Inlay IC-8 and Xtrafocus). These implants have a so-called aperture (a built-in pinhole) - a blackened ring with a small, transparent hole in the middle, the so-called pinhole.

Current applications in the eye still show considerable weaknesses.

Patients currently only benefit from this idea if the implants can be repositioned in a refractive procedure. read more: During the healing process, the lens can slip out of the visual axis and vision is reduced. In addition, precise placement and alignment of the lens is tricky for the surgeon. In any case, the standardized, prefabricated aperture does not meet the individual requirements and physical conditions of all patients.

State-of-the-art laser brings sharpness to artificial lenses.

Femto-Masking can laser a pinhole mask (small aperture) in the majority of all commercial artificial lenses. read more: The procedure is only applied after successful implantation and can extremely improve the sharp near and intermediate vision. Patients experience a significant improvement in vision immediately after application.

ROWIAK Femto-Masking is an optimal application to use the advantages of pinhole optics and to avoid the disadvantages of solutions currently available on the market.

Due to the non-invasive nature of the application there are no problems with wound healing. The centering of the laser-generated mask can be easily and precisely aligned along the patient's visual axis. In addition, unlike the small aperture implants available on the market, the procedure offers full flexibility in adjusting the aperture. Each laser-generated mask meets the individual needs of the patient. Application is quick and does not require a sterile environment.

ROWIAK Femto Masking is currently in the development process and will soon enter clinical trials.
