Visionstar MD-960

Frequency Doubled Solid State Source

The treatment beam comes from a diode pumped, frequency doubled solid state laser, an architecture with no gas tube or dye circuit to maintain, which is what keeps the console small and the servicing burden modest.

532nm Green Continuous Wave

The treatment wavelength is 532nm in the green, described as true continuous wave rather than a pulsed source shaped into an apparent continuous output.

Adjustable Power Output

Power runs from 50mW to 1200mW and is adjustable, giving a wide span between the lowest and highest settings the console will deliver.

Adjustable Pulse Timing

Pulse duration is adjustable from 0.01s to 3s and the interval between pulses from 0.05s to 1s, both set at the console by the operator, giving fine control over how energy is applied within any single application.

Separate Aiming Beam

A laser diode aiming beam operates between 630 and 680nm at under 1.0mW and is itself adjustable, allowing positioning before treatment energy is applied.

Continuously Adjustable Spot

Spot size adjusts continuously from 50 to 500 microns, which the manufacturer relates to a homogeneous photocoagulation spot at the retina rather than an uneven one.

Closed Loop Power Control

The manufacturer describes a closed loop power control system holding output stable without degeneration, so the delivered energy matches the setting selected.

Detachable Slit Lamp Delivery

Delivery is through a slit lamp adapter described as detachable and compatible with a range of slit lamp microscopes, with a compact air cooled console alongside.

Retinal Photocoagulation

A green continuous wave source at 532nm is the established wavelength for retinal photocoagulation, absorbed well by the pigment layers that clinicians target while passing readily through the ocular media. Power from 50 to 1200mW with pulse durations from 0.01s to 3s gives the operator a broad envelope within which to work. What settings suit a given patient and indication is entirely a clinical judgement for the treating ophthalmologist and lies outside anything a product page should suggest.

Slit Lamp Based Treatment

Delivery through a slit lamp adapter means treatment happens at a microscope the clinician already knows, with the stereoscopic view and controls they are practised on. The aiming beam at 630 to 680nm allows the target to be positioned before any treatment energy is delivered. Because the delivery system detaches, the laser is not permanently committed to one microscope in one room.

Working Across More Than One Room

A console measuring 30cm by 28cm by 14cm with air cooling and a thermoelectric cooler is small enough to move between clinics rather than occupy a dedicated laser room permanently. For a service running laser lists intermittently, or across more than one site, that changes the economics of owning a laser at all, since the equipment is not idle whenever a particular room is in other use.

Fine Control of Spot and Energy

Continuous adjustment of spot size from 50 to 500 microns, combined with adjustable power and timing and a closed loop control system, gives the operator granular control over what is delivered. Consistency between the setting chosen and the energy applied is what allows a clinician to build reliable experience of how the system behaves over time.

Consistency Between Setting and Delivery

The closed loop power control system described by the manufacturer addresses the quiet problem with any treatment laser, which is drift between what the console displays and what actually reaches the tissue. Output held stable without degeneration means a clinician's accumulated sense of how a given setting behaves stays valid over the life of the system, and that accumulated judgement is worth more than any headline figure on a specification sheet.

A Wide Working Envelope

Power from 50 to 1200mW, pulse duration from 0.01s to 3s, interval from 0.05s to 1s and spot size continuously variable from 50 to 500 microns together give an unusually broad range at the operator's disposal. A system that reaches both ends of the envelope avoids the situation where a clinician adapts their technique to the limitations of the equipment rather than to the patient in front of them.

Not Tied to One Room

A detachable delivery system, compatibility across a range of slit lamp microscopes and a console of modest footprint mean the laser can follow the list rather than the list following the laser. Air cooling with a thermoelectric cooler removes any water supply requirement. For services without the volume to justify a dedicated laser suite, that flexibility is often what makes the purchase viable.

The Visionstar MD-960 is a compact green treatment laser built around control. A diode pumped, frequency doubled solid state source delivers 532nm true continuous wave at 50 to 1200mW, with pulse duration adjustable from 0.01s to 3s, interval from 0.05s to 1s and spot size continuously variable from 50 to 500 microns. An aiming beam at 630 to 680nm under 1.0mW supports positioning, a closed loop control system holds the output stable, and a touch screen console of 30cm by 28cm by 14cm is air cooled with a thermoelectric cooler.

This page states what the technical data states. The mains electrical specification is deliberately not given here, and mass, safety interlocks, protective eyewear, service requirements, configuration and condition do not appear on the material held. Which slit lamp microscopes the adapter fits should be confirmed rather than assumed. Nothing here should be read as a claim about testing or regulatory approval, and a system of this kind is intended for appropriately trained clinicians working within a controlled laser environment.
