Visionstar SW-2100

Ophthalmology clinics use B-scan imaging when the fundus cannot be viewed directly, which is the situation the modality is intended for. The manufacturer states that the SW-2100 is used for the diagnosis of intraocular disease, showing the location, shape,aandd extent of a lesion and its relationship with surrounding tissue, and lists vitreous opacity, retinal detachment  ,a nd ocular fundus tumours among the conditions assessed. Those are the manufacturer's stated applications. All image interpretation and clinical decision-making remain with the practitioner, and Medigear.uk verifies certification and regulatory status before any procurement decision is made.

Cataract and IOL planning is served by the A-scan side, which measures anterior chamber depth, lens thickness, vitreous body length and total axial length with averaging, at a stated precision of ±0.05 mm. Phakic, aphakic, dense and various IOL eye modes cover the range of presentations, and built-in formulae calculate implant power. Which formulae are included matters to a surgical service, and Medigear.uk confirms them in writing.

Optometry practices offering enhanced services gain from a 4 kg laptop-connected system rather than a fitted console, since it can be moved between rooms or carried to a satellite clinic. Practices should establish the required computer specifications before purchase, as the workstation is supplied by the practice rather than the manufacturer. A system that will not run on existing hardware carries a cost that never appears on the quotation.

Services building a patient record benefit from PDF report output and AVI or JPG image export, with a 100-image movie review available where a finding is better assessed in motion than on a still frame. Medigear.uk supplies the reporting documentation with the system.

A-Scan and B-Scan in a Single System

One unit covers both biometry and imaging, where many practices run separate instruments for each. Four operating modes allow a B-scan image and an A-scan trace to be displayed together rather than requiring a switch between applications. For a clinic with limited room space and a mixed caseload, consolidation is worth as much as capability.

IOL Power Calculation Built In

The A-scan carries IOL formulae rather than exporting measurements to a separate calculator, which removes a transcription step from surgical planning. Anterior chamber depth, lens thickness, and axial length directly feed into the calculation. Medigear.uk confirms which formulae are included, since that determines whether it suits a given surgical protocol.

Sixty Millimetres of B-Scan Depth

Scan depth determines how much of the posterior segment and orbit is visualised in a single sweep, and 60 mm covers the axial length of the eye with margin—combined with a 53-degree scanning angle, this provides a useful field in a single acquisition. Depth and angle together define what an examination can actually show.

Dual-Frequency Probe Option

A 20 MHz probe is available alongside the standard 10 MHz probe, offering higher resolution with reduced penetration for anterior segment work. Having the option means the system can be specified for the caseload rather than accepting one compromise frequency. Medigear.uk confirms availability and pricing at quotation.

Vitreous and Retina Enhancement Modes

The manufacturer provides enhancements for the vitreous body and retina, alongside a vitreous-plus function, addressing low-reflectivity structures that are hardest to render on a standard gain setting. Probe gain, adjustable from 30 dB to 105 d, provides additional latitude. Both are standard rather than optional.

Reporting Ready for the Patient Record

PDF report output, AVI and JPG image export and 100-image movie review mean examination output goes into a record without a separate conversion step. Measurement tools covering distances, perimeters and areas are built into the workstation. For a service that must evidence findings, this is a workflow feature rather than a technical one.

Four Kilograms and Laptop-Connected

At 4 kg and 200 × 160 × 450 mm, the system moves between rooms or to a satellite clinic without difficulty and runs on a laptop rather than requiring a dedicated console. Portability of this order changes where a service can be delivered. The practice supplies the computer, so specification requirements are confirmed before order.

Certification and Regulatory Status Verified Before Order

This is a diagnostic medical device, and its certification needs to be current, valid and specific to this model rather than assumed from a listing. Medigear.uk obtains the documentation and confirms the applicable parking and registration before supply before any order proceeds. Buyers therefore commit against verified compliance rather than a stated claim.

B-Scan Depth: 60 mm

B-scan penetrates to 60 mm, covering the axial length of the eye with margin for orbital structures. Depth determines how much is visualised in a single sweep. It is a published manufacturer specification.

B-Scan Frequency: 10 MHz with 20 MHz Optional

The standard probe operates at 10 MHz, with a 20 MHz probe available as an option for higher resolution at reduced penetration. Frequency choice follows the caseload. Medigear.uk confirms the optional probe is available in the quotation.

B-Scan Resolution: 0.3 mm Lateral, 0.2 mm Vertical

Lateral resolution is 0.3 mm and vertical resolution is 0.2 mm, with geometric position precision quoted at 10 per cent lateral and 5 per cent vertical. These figures determine the smallest detail that can be distinguished in an image.

Scanning Mode and Angle: Sector at 53 Degrees

B-scan uses sector scanning across a 53-degree angle. The scanning angle, together with depth, defines the field captured in a single acquisition. Both are published specifications.

Magnetic-Driven Noiseless Probe

The manufacturer specifies a magnetic-driven probe described as noiseless. Probe noise matters during examination of anxious or paediatric patients, where mechanical sound affects cooperation.

Probe Gain: 30 dB to 105 dB

Gain adjusts over a 75 dB range, providing latitude to render both high- and low-reflectivity structures. Gain control is central to distinguishing vitreous opacity from retinal detachment on B-scan.

Grey Scale: 256 Levels with False Colour

Images render across 256 grey levels, with multi-colour false colour available. Grey scale depth determines how finely differences in tissue reflectivity are represented.

A-Scan Depth: 40 mm at ±0.05 mm Precision

The A-scan operates to 40 mm, with a stated precision of ±0.05 mm at 10 MHz, with LED indication. Precision at this level is what makes the measurements usable for IOL calculation.

A-Scan Biometry Measurements

The system measures anterior chamber depth, lens thickness, vitreous body length and total axial length, with averaging across readings. These are the inputs to implant power calculation.

Four Eye Modes

Phakic, aphakic, dense, and various IOL modes are provided, allowing the system to be set to the presentation rather than applying a single velocity assumption. Mode selection directly affects measurement accuracy.

IOL Power Calculation

Implant power formulae are built into the system rather than requiring export to a separate calculator. Which formulae are included determines suitability for a given surgical protocol. Medigear.uk confirms them in writing.

Four Operating Modes

B, B+B, B+A and A modes are supported, allowing imaging and biometry to be displayed separately or together. Side-by-side display removes the need to switch applications during an examination.

Vitreous and Retina Enhancement with Vitreous Plus

Enhancement modes for the vitreous body and retina are provided alongside a vitreous-plus function, targeting the low-reflectivity structures that are hardest to render at standard gain.

Measurement and Post-Processing Tools

Measurement covers multigroup distances, perimeters, and areas, with multiple curve-processing and pseudo-colour post-processing available on captured images.

Movie Review and Image Export

The system holds 100 images for movie review and exports in AVI and JPG formats. Dynamic review matters where a finding is best assessed in motion rather than on a still frame.

PDF Report Output

Reports are generated as PDFs directly from the workstation, making the output straightforward to attach to a patient record without a separate conversion step.

Dimensions, Weight and Computer Requirement

The unit measures 200 × 160 × 450 mm, with a net weight of 4 kg and a gross weight of 5 kg. It runs on a practice-supplied laptop, so the operating system and connection requirements are obtained from the manufacturer by Medigear.uk before ordering.

The Visionstar SW-2100 Ophthalmic Ultrasound combines A-scan biometry and B-scan imaging in a single 4 kg laptop-connected system, offering 60 mm B-scan depth across a 53-degree sector at 10 MHz with a 20 MHz probe optional, ±0.05 mm A-scan precision across four eye modes, and built-in IOL power calculation. That combination suits ophthalmology clinics assessing the posterior segment, where the fundus cannot be viewed directly; cataract and IOL planning services; optometry practices offering enhanced services; and any service building an evidence-based patient record through PDF and image export. Because this is a diagnostic medical device, certification is verified as current and specific to this model, and the applicable marking and registration positions are confirmed in writing before supply, alongg with the service arrangements and probe availability.
