About us

ROWIAK GmbH has established the innovative supremacy of Femtosecond Laser Technology in Life Sciences and Ophthalmic Laser Surgery Market. This Ultrafast Laser Technology as a tool for simultaneously processing and imaging of tissue is closely associated with the name ROWIAK.

ROWIAK GmbH now is focused on laser-assisted microsurgery of the eye. In 2014 ROWIAK has successfully completed a controlled trial of laser-assisted cataract surgery. Another, based thereon study started in spring 2015. In addition ROWIAK develops customized medical devices and custom-made contract research.

ROWIAK GmbH combines optical technologies that have already been used successfully as standalone solutions. This leads to the creation of innovative products and the exploration of new scientific fields and markets.

Technology & Product History

The basic technologies offered by ROWIAK are ultrashort laser pulses for preparation and processing of biological tissue as well as imaging the target tissue. Ultrashort pulses (sometimes also called ultrafast pulses) are laser pulses with a duration of less than 1 picosecond (1ps = 10-12 s). Ultrashort pulses can generate extremely high intensities which induce so called non linear interactions such as spontaneous absorption of radiation in original transparent media. Moreover, ultrashort pulses show spectral characteristics, which are ideal for imaging techniques.

Based on this technology ROWIAK has developed a Laser Microtome ('TissueSurgeon'), which replaces the conventional, mechanical knife by laser light. In order to control the cutting process on line, ROWIAK has integrated a so called OCT imaging system into the TissueSurgeon, which enables visual control inside the tissue with micrometer precision ('Seeing Knife').

For the manipulation and visualization of smallest intracelluar structures and processes ROWIAK has developed a so-called Nanotome ('CellSurgeon') in collaboration with the Laser Zentrum Hannover (LZH). The CellSurgeon also uses femtosecond laser technology, integrated into a microscope and enables the user to create cuts in living cells, with a precision in the nanometer range.

In contrast to the TissueSurgeon, where the processed specimen treated by microscopic mechanical tools such as tweezers, the Nanotome penetrates into dimensions, where mechanical manipulation becomes impossible. Important is the imaging of the processed area. This is realized by conventional light microscopy and can be expanded to Multiphoton Microscopy, which is also performed by ultrashort laser pulses and leads to a higher resolution with less bleaching effects on the target area.

Based on the same technology of tissue processing with ultra fast laser pulses, ROWIAK is developing a laser system, which will be used for the treatment of cataracts and also presbyopia.
