LIGHTLas 532
Green Photocoagulation Laser. True Solid-State 2.0W with SP-Mode® Microsecond Laser Technology
LIGHTLas 532
Green Photocoagulation Laser
The LIGHTLas 532 delivers true solid-state 2.0W of 532nm green laser energy with dual operational modes. For patients, SP-Mode® Microsecond Laser Technology means gentler, tissue-sparing treatments without visible burns, reducing discomfort and the frequency of anti-VEGF injections. For practices, it means a compact, reliable console with multiple delivery options that handles your entire retinal laser workflow from one device.
- Comprehensive CW and SP-Mode® Capability: Delivers traditional Continuous Wave photocoagulation for PRP, focal, and grid treatments, alongside SP-Mode® sub-threshold therapy for tissue-sparing care with reduced discomfort and no visible burns.
- True solid-state 2.0W at 532nm: delivering a stable, reliable green wavelength with optimal hemoglobin and melanin absorption for precise treatment and long-term system durability.
- Multiple delivery options: compatible with slit lamp, laser indirect ophthalmoscope, and endophotocoagulation probes.
- 7-inch LCD touchscreen: intuitive interface with saveable treatment protocols for fast workflow.
532nm Green Wavelength
Green laser is preferentially absorbed by hemoglobin and melanin, making it ideal for retinal photocoagulation. The 532nm wavelength provides excellent contrast against retinal pigment epithelium while minimizing absorption in yellow macular xanthophyll pigments.
SP-Mode® Microsecond Laser Technology
Built-in sub-threshold microsecond pulsing mode enables tissue-sparing laser therapy without visible burns. SP-Mode® stimulates retinal pigment epithelium biological response while preserving photoreceptor integrity, reducing the frequency of anti-VEGF injections and improving patients’ quality of life.
Conventional Continuous Wave
Traditional Continuous Wave (CW) photocoagulation mode for panretinal photocoagulation, focal macular treatment, and grid patterns. Adjustable power (50–2000 mW) and duration (10–3000 ms) provide complete control for all standard retinal laser applications.
7-Inch Touchscreen Interface
Intuitive LCD touchscreen simplifies parameter adjustment and mode switching. Save multiple treatment protocols for different conditions so you can recall settings instantly, speeding up workflow and reducing setup time between patients.

Multiple Delivery Options
Connect to LaserLink integrated slit lamp, Haag-Streit adapter, laser indirect ophthalmoscope, or 20G/23G/25G endophotocoagulation probes. One console supports office-based and intraoperative workflows across all delivery modalities.
True Solid-State Design
Diode-pumped solid-state laser technology eliminates lamp replacement and reduces maintenance compared to older gas laser systems. The compact, reliable design delivers consistent 2.0W output with minimal downtime over the system’s lifetime.
Combo System Availability
Available as a standalone console or as part of a YAG-V/532 or SLT Deux-V/532 combo system. Expand your anterior and posterior segment capabilities from a single platform, maximizing your investment and simplifying your equipment footprint.

What Sets LIGHTMED's 532nm Apart
LIGHTMED was among the earliest companies in the world to develop diode-pumped Nd:YAG → KTP 532nm green laser architecture for retinal photocoagulation. Over more than two decades, this platform has been continuously refined for stable energy output, precise beam quality, and exceptional system longevity.
While many 532nm green lasers are available today, most rely on architectures that degrade within a few years. LIGHTMED's diode-pumped solid-state design eliminates the thermal stress and internal wear common in older flashlamp and gas laser systems. The result is a laser that routinely delivers up to 10 years of reliable clinical operation.

TESTIMONIALS
What Physicians Are Saying
“The LIGHTLas 532 green laser photocoagulator is a safe and user-friendly device for treating various retinal diseases. It includes an intuitive touch panel that allows practitioners to easily save multiple settings for different treatment protocols. The laser itself is excellent and high-quality, but the best feature is LIGHTMED’s SP-Mode® Microsecond Laser Technology that provides sub-threshold microsecond pulse treatment. SP-Mode® is tissue-friendly and empowers physicians to safely treat their patients without causing burns to retinal tissue. It reduces the frequency of anti-VEGF injections which has improved my patients’ quality of life. This single laser function truly presents a shift in treatment paradigm allowing for new photo stimulation capabilities.”

“Our clinics have used LIGHTMED lasers for a couple years now and we are very pleased. They perform at least as well; if not better than, what we used before and the service is outstanding. We were pleasantly surprised to find that the lasers are a better value financially and the warranty with service costs are more practice friendly as well. I like the ergonomics. The laser is easy to use and intuitive.”

“The advantage to having the LIGHTLas 532 with SP-Mode® combined with the SLT Deux-V is that you can do so much more with it. The optics are so superior on the LIGHTMED machine. With the gonio lens everything is clear especially when finding the trabecular meshwork. Essentially you have one machine that fits all offices, offering three different approaches to glaucoma: SLT, SPLT, YAG PI, and you can also treat the retina with SP-Mode® laser.”
