Ophthalmic laser system for micro-invasiveglaucoma surgery (MIGS).
The MLI series consists of excimer lasers with direct wavelength for industrial applications. We can, of course, adapt our basic devices to meet your individual requirements.
Individual components
MLase’s modern, compact MLI excimer lasers are UV light sources at wavelengths of 193 nm or 248 nm with high pulse energies of up to 16 mJ and pulse repetition frequencies of up to 1,000 Hz.
They are stand-alone devices with the longest service life and highest degree of reliability available on the market, combined with the lowest operating costs. Their homogeneous steel profile and energy stabilisation makes them highly suitable for demanding applications.
Our LC excimer laser systems are additionally capable of active water cooling (using domestic water or an external heat exchanger; no purified water) for stable continuous operation.

The ExTra – a XeCl excimer laser – was CE certified in 2014 (identification number: 0197) and has been specially developed for the performance of an ELT (Excimer Laser Trabeculostomy).
The ELT is a MIGS-procedure (Micro-Invasive-Glaucoma-Surgery) for the ab interno treatment of open-angle glaucoma.
During the ELT, tunnel-like passageways are lasered into the trabecular meshwork at the iridocorneal angle by means of non-thermal Photoablation. This creates a connection between the front section of the eye and the Schlemm´s canal, improving the drainage properties.
With the ELT, the laser light is guided to the trabecular meshwork in the iridocorneal angle via a small corneal incision by means of an optical fiber suitable for UV light and embedded into a lightweight laser applicator. With the aid of a gonioscopy lens the fiber end can be positioned precisely at the application site.
To achieve an easier drainage of the aqueous humor to reduce IOP, a total of 10 ELT channels with 200µm diameter each are lasered into the trabecular meshwork by means of non-thermal photoablation. In comparison, stents and implants have only individual diameters between 80 – 120 µm.
The ELT-procedure takes advantage of a practically maintenance-free, encapsulated and easy-to-use ExTra XeCl excimer laser with a tissue-friendly wavelength of 308 nm.
In comparison to alternative methods, the lack of heat generation not only leads to an almost absent activation of postoperative tissue reactions, but also to an excellent long-term stability of the pressure-reducing effect. The stability of Schlemm’s canal remains unchanged.
The micro-invasive ELT which can only be performed with the ExTra is remarkably uncomplicated and can easily be combined with any other given intraocular treatment such as phacoemulsification.
The ExTra is mobile and both fast and easy to use. Thus, it can be easily integrated into any clinical workflow.

MLase AG is specialised in developing and producing medical lasers and accessories for treating corneal diseases and related ectatic disorders. Whether you are looking for information on the ophthalmic laser system for glaucoma treatment or the CCL-Vario for keratoconus treatment, you can find out more about the fields of application for MLase medical technology here.
Minimally invasive glaucoma surgery has become a recognised method of treatment. ELT (excimer laser trabeculotomy) does not require the use of implants.
Corneal cross-linking (CXL), also known as collagen cross-linking, is an outpatient treatment to strengthen the corneal stroma. This is achieved by means of creating new chemical bonds between the stroma fibres.
