Ophthalmic Laser Photocoagulators
Ophthalmic laser photocoagulators are the workhorse platforms behind retinal and glaucoma treatment in the modern eye practice. By delivering a precisely focused beam through a slit lamp, laser indirect ophthalmoscope (LIO), or endoprobe, these systems let clinicians seal retinal tears, ablate leaking or proliferating vessels, treat diabetic retinopathy and vein occlusions, and lower intraocular pressure. Wavelength is what separates one instrument from another: a green (532 nm) beam is strongly absorbed by hemoglobin and melanin, making it the everyday standard for panretinal and focal work, while an infrared diode (810 nm) beam penetrates deeper and is well suited to ablation and transscleral cyclophotocoagulation. Choosing the right laser is less about brand prestige and more about matching wavelength, delivery system, and treatment mode to the procedures you actually perform.
At US Ophthalmic we support ophthalmologists, retina specialists, and surgical practices as a true equipment provider, not a pass-through reseller. Every laser we place is backed by our in-house technical and repair department, US-based warranty and service, and a dedicated spare-parts operation, so a photocoagulator you buy today stays clinically dependable for years. Alongside our own EZER house brand of ophthalmic and optometric instruments, we carry the Meridian Merilas laser line, giving you a considered range of green and infrared platforms rather than a catalog dump. Whether you are equipping a new clinic or replacing an aging unit, our team helps you scope the right configuration and keeps it serviceable long after the sale.
How to choose an ophthalmic laser
- Match the wavelength to your caseload: Green 532 nm is the versatile default for panretinal photocoagulation, focal/grid treatment, diabetic retinopathy, vein occlusions, and trabeculoplasty, thanks to strong hemoglobin and melanin absorption. Infrared 810 nm penetrates deeper with less scatter, favoring ablation, tumor work, and transscleral cyclophotocoagulation for glaucoma, and it can be preferable in eyes with media opacity. Many practices standardize on green and add an 810 platform for the deeper-penetration procedures they perform.
- Confirm the delivery system fits your workflow: The same laser source can be delivered several ways. A slit-lamp adapter (check compatibility with Haag-Streit or Zeiss-style lamps) suits seated in-office treatment; an LIO enables peripheral and pediatric retinal work such as ROP; and endoprobes or transscleral probes support intraoperative and external procedures. List the delivery paths you need before comparing systems.
- Look at treatment modes, not just power: Beyond continuous-wave delivery, short-pulse or subthreshold modes fire energy in microsecond bursts so tissue cools between pulses, reducing collateral heating for more tissue-sparing macular and focal treatments. If subthreshold or micropulse-style work is part of your practice, prioritize a platform that offers it natively.
- Weigh footprint, portability, and integration: Compact, thermoelectrically cooled units with a carrying case travel easily between rooms or satellite offices and mount onto slit lamps you may already own, protecting your prior investment. Confirm whether the laser integrates with your existing lamp or requires a dedicated stand and space.
- Plan for service, warranty, and spare parts: A Class 4 surgical laser is a long-term asset, so uptime matters. Prioritize a provider with in-house repair capability, US warranty coverage, and genuine spare-parts availability over a broker who only ships boxes. This is where working with a service-backed provider pays off across the device's life.
- Decide between new and certified refurbished: New systems offer the latest firmware, full manufacturer warranty, and maximum remaining service life. Properly refurbished lasers, function-tested and calibrated to specification by trained technicians and backed by warranty, can extend budget for a second room or a starting practice. The deciding factor is who stands behind the unit, not the price alone.

| Model | Wavelength / Type | Best for |
|---|---|---|
| Merilas 532 | Green (532 nm), short-pulse photocoagulator | Everyday panretinal and focal work: diabetic retinopathy, vein occlusions, retinal tears and detachment, macular edema, plus trabeculoplasty and iridotomy |
| Merilas 810 | Infrared diode (810 nm) | Deeper-penetration procedures: retinal ablation, subretinal neovascularization, ROP via LIO, and transscleral cyclophotocoagulation for glaucoma |
| Merilas α532 | Green (532 nm), single-spot photocoagulator | Practices wanting a straightforward green photocoagulation platform for routine retinal and glaucoma laser treatment |
Frequently asked questions
What is the difference between a 532 nm green laser and an 810 nm diode laser? The 532 nm green wavelength is strongly absorbed by hemoglobin and melanin, making it the standard for surface retinal and vascular work such as panretinal photocoagulation, diabetic retinopathy, and focal treatment. The 810 nm infrared diode wavelength penetrates deeper with less absorption at the retinal surface, which suits ablation, transscleral cyclophotocoagulation for glaucoma, and eyes with some media opacity. Many practices keep a green laser for daily use and add an 810 platform for deeper-penetration procedures.
Can these lasers be used with a slit lamp I already own? In many cases, yes. The Merilas platforms offer slit-lamp adapters compatible with common Haag-Streit and Zeiss-style lamps, along with LIO and endoprobe delivery options. Tell us which slit lamp and delivery method you use, and we will confirm compatibility before you order so you can protect existing equipment.
What is short-pulse or subthreshold mode, and why does it matter? Short-pulse (subthreshold) modes deliver laser energy in brief microsecond bursts, allowing tissue to cool between pulses. This reduces collateral heating for gentler, more tissue-sparing treatment, which clinicians often prefer for macular and focal applications. If that style of treatment is part of your practice, choose a laser that supports these modes natively rather than continuous-wave only.
Do you sell new and refurbished ophthalmic lasers, and are they serviced in the US? We provide both new and properly refurbished systems, and every laser is backed by our in-house technical and repair department, US warranty coverage, and genuine spare-parts support. As an equipment provider rather than a broker, we stand behind the device after the sale, so it stays clinically dependable and serviceable over its full life.
What conditions can an ophthalmic laser photocoagulator treat? Depending on wavelength and configuration, these systems treat proliferative and non-proliferative diabetic retinopathy, branch and central retinal vein occlusion, retinal tears, detachment and lattice degeneration, choroidal neovascularization, macular edema, retinopathy of prematurity, and select tumors, as well as glaucoma procedures such as trabeculoplasty, iridotomy, and transscleral cyclophotocoagulation. Our team can help match the platform to the procedures you perform most.
