In cataract and refractive surgeries, femtosecond lasers operate with remarkable precision. These lasers emit ultrashort pulses of light, allowing surgeons to create accurate incisions and perform tissue ablation with minimal disruption to surrounding structures. The laser’s ability to target specific tissues, as well as its non-invasive nature, makes it an invaluable tool in improving surgical outcomes and enhancing patient recovery.

Understanding Cataracts

A cataract is a common eye condition characterized by the clouding of the eye’s natural lens. This cloudiness typically develops due to ageing or other factors such as genetics or environmental influences. Cataracts progressively obstruct the passage of light through the lens, leading to blurred or hazy vision. In cataract surgery, the cloudy lens is replaced with an artificial intraocular lens (IOL) to restore clear vision.

Femtosecond lasers have ushered in a transformative era in ophthalmic procedures, most notably in the field of cataract surgery; they play a pivotal role by offering precise and efficient solutions.

Refractive Surgery

LASIK Operation

Refractive surgery encompasses a range of procedures to correct vision problems, such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.

These procedures are designed to reduce or eliminate the need for glasses or contact lenses.

One common type of refractive surgery is LASIK (Laser-Assisted In Situ Keratomileusis), which reshapes the cornea to improve how light enters the eye and focuses on the retina.

Lenticule Extraction

Amplitude has pioneered the procedure for refractive surgery for the past 20 years, collaborating closely with top manufacturers in the field.

The use of our femtosecond lasers has replaced outdated techniques and significantly improved surgical outcomes while minimizing post-procedure discomfort.

Today, as a leader in LASIK and Lenticule Extraction, we continue to guide our partners in achieving excellence in the field.

Amplitude supports Innovative Glaucoma Management by pioneering femtosecond lasers for trabeculotomy surgery. This breakthrough technique enhances the eye’s drainage system, lowering intraocular pressure and advancing minimally invasive treatments for glaucoma.

The integration of laser technology into ophthalmology represents a significant advancement in vision care. Beyond cataract and refractive surgeries, lasers are instrumental in treating various eye conditions. With ongoing technological progress, the future of ophthalmology promises refined treatments, advanced diagnostics, and improved vision care, ultimately elevating the quality of life for individuals worldwide.

Medical components such as implants and surgical tools require perfected manufacturing processes. The slightest alteration of the surface, the dimensions or the form may have a significant impact on their performance.

For these sophisticated and demanding applications, ultrafast lasers (femtosecond or picosecond) offer unique advantages: they can work on any type of material (ceramic, glass, polymer, metals) without emitting heat, and with both remarkable precision and exceptional quality. They are of a higher average strength and can therefore increase industrial productivity and accuracy.

Among the typical applications, we can cite the production of new generation bio-absorbable stents, catheter treatment or texturing the surfaces of biocompatible implants. New applications are currently under active development, notably in the area of nano-technologies and manufacture of advanced additives.

Amplitude proposes a complete range of ultrafast lasers, of industrial reliability and perfectly adapted to these advanced applications. Feasibility studies or process development can be produced in partnership with our applications laboratory. Biocompatible materials are rare and must be manufactured on a very small scale in order to be injected. The nature of the material used is of paramount importance and must not be changed in any way. Absorbed by the body, these materials are fragile and poorly allow the interaction with certain lasers.
Our lasers solve this problem. With their extremely high repetition rates, our lasers prevent any change in the integrity of the biomaterial, such as corrosion resistance, making femtosecond technology the best option to use. Operating at this precision height, Amplitude-femtosecond lasers are the most in tune with the expectations of our customers manufacturing medical devices.

Proton therapy is the treatment of cancerous tissues using protons or beams charged with heavy ions. Unlike X-rays or electrons, which tend to deposit energy over a large region of the tissue, protons deposit most of their energy at a very specific depth. The actual depth depends on the initial energy of the protons. As a result, proton beams can be used to remove tumors without collateral damage.

Proton therapy is currently used in about 30 facilities around the world, using large and expensive accelerators. This technology poses a clear limitation to access this treatment.

As an alternative, physicists are looking at how compact femtosecond lasers could be used to develop smaller and less-costly proton sources. The basic principle consists of shooting an intense, short laser pulse at a thin solid target. The protons and other ions are pushed out of the target by the electrons and subsequently accelerated into the laser electric field, over distances as small as a few microns.

Amplitude manufactures table-top intense lasers to generate heavy ions and protons beams. We help researchers around the world studying how to generate the proton beams and how these beams interact with living cells. The Pulsar product line has been designed to provide certain important features required by physicians in this domain, such as contrast ratio, beam quality, and stability.
