Photocoagulation: Retinal photocoagulation, pan-retinal photocoagulation (PRP) and intravitreal endophotocoagulation of vascular and structural abnormalities of the retina and choroids, including:
■ Proliferative and non-proliferative diabetic retinopathy
■ Choroidal neovascularization
■ Branch retinal vein occlusion
■ Age-related macular degeneration
■ Retinal tears and detachments
■ Retinopathy of prematurity
■ Macular edema
■ Lattice degeneration
■ Central retinal vein occlusion

Iridotomy:
■ Iridotomy in angle closure glaucoma

Trabeculoplasty:

The Haag-Streit instruments provide precise and safe treatment capabilities, thanks to their internal beam path. These instruments do not have any external parts that could be misaligned, ensuring accurate and consistent performance. Additionally, the unique 'Clear View' user protection filter adds another layer of safety.
The laser is directly integrated into the illumination path of the slit lamp, eliminating any additional obstacles between the slit lamp front lens and the patient's eye. This direct linkage ensures unobstructed visibility and enhances safety during the treatment process.

• The 577 nm yellow wavelength minimizes the occurrence of retinal burns, resulting in reduced scotoma formation.
• This wavelength provides physicians with improved control over the interaction between the laser beam and tissue during treatments.
• Yellow light is not absorbed by xanthophyll, making it particularly suitable for macular treatments.
• Additionally, the 577 nm wavelength produces less scattered light, allowing it to penetrate existing opacities more effectively and reach the tissue with greater precision.

The short-pulse treatment mode is characterized by a sequence of bursts comprising microsecond pulses. This treatment mode aims to spare the tissue and minimize scarring by delivering non-visible, subthreshold laser impacts. It effectively treats various retinal pathologies while avoiding ophthalmoscopically observable laser effects on the treated tissue. The short-pulse treatment is commonly utilized for subvisible threshold laser treatments targeting the macular and perimacular areas. Extensive studies on 577nm wavelengths have demonstrated the clinical efficacy of subvisible laser treatments without causing tissue damage.

AVAILABLE TREATMENTS:

• For macula treatment:
  Diabetic Macular Edema (DME) is a common complication of diabetes, affecting the macula due to fluid accumulation. This condition can cause vision loss and requires prompt intervention.
  Central Serous Retinopathy (CSR) is characterized by fluid leakage in the macula, leading to blurred or distorted vision.
• For proliferative diabetic retinopathy, panretinal photocoagulation (PRP) and anti-VEG therapy are commonly used treatments.
• Retinal tears and detachments can be treated through a process called "soldering" or "welding," in which a laser is used to seal the retina back in place.
• Ablation treatments, such as laser peripheral iridotomy (LPI), can be used to treat various eye conditions, including narrow-angle glaucoma.

The standard accessories include a foot switch, transport case, and safety goggles. The optional accessories include slit lamp adapters, laser indirect ophthalmoscope, safety filters (passive and active), endoprobes, and an external fan.

• Foot switch: The foot switch is used to turn the laser on and off. It allows the surgeon to operate the laser without using their hands, which can help improve accuracy and reduce the risk of accidental firing.
• Transport case: The transport case is used to store and transport the laser safely. It helps protect the device from damage during transportation and storage.
• Safety goggles: The safety goggles are worn by the surgeon and other personnel in the room to protect their eyes from the laser light. They help prevent eye damage and reduce the risk of accidental exposure to laser radiation.
• External fan (OPTIONAL ACCESSORY): The external fan is used to cool the laser device during operation. Lasers generate a lot of heat, and the external fan helps prevent the device from overheating and potentially malfunctioning.
