Visionstar SK-3000

Glaucoma assessment involves the use of a pachymeter. Central corneal thickness affects how measured intraocular pressure should be interpreted, and a service assessing suspects without it is working from an uncorrected figure. At 20 MHz, over a 0.3-1.5 mm range with an accuracy of ≤0.01 mm, the pachymeter comfortably covers the clinical range. Medigear.uk confirms the pachymeter specification for the supplied build, as this is the modality that distinguishes the model.

Refractive surgery screening depends on the same measurement, since residual stromal bed calculation and candidate selection both rest on corneal thickness. Combining that with axial length biometry in a single instrument means the screening workup runs on a single device rather than across two. All interpretation and candidate assessment remain with the practitioner.

Cataract and IOL planning uses the A-scan side with comparison across formulae and standard deviation calculation. This is where the divergent published specifications matter most, since sources differ on measurement range, accuracy and the number of formulae provided. A surgical service should treat those figures as unconfirmed until Medigear.uk has obtained them for the specific build being quoted.

Ophthalmology clinics use B-scan when the fundus cannot be viewed directly, operating at 10 MHz to 60 MHz and achieving depths of 60 mm or greater across a 53-degree angle. WWhena post-gain function is fitted, a frozen acquisition can be reviewed across gain levels without rescanning, which shortens contact time with anxious or paediatric patients and reduces the number of repeat sweeps arequired for  difficult examination  Medigear.uk confirms whether that function is present on the build supplied

Three Modalities in One Instrument

A-scan biometry, B-scan imaging and corneal pachymetry sit in a single unit, where a practice would otherwise buy pachymetry as a separate instrument. Consolidation saves both capital and clinic room space. For a service covering cataract, glaucoma and refractive screening, it removes an entire device from the equipment list.

Pachymetry for Glaucoma and Refractive Screening

Corneal thickness measurement at 20 MHz across 0.3 to 1.5 mm addresses two applications neither biometry nor imaging reaches: interpreting measured intraocular pressure in glaucoma assessment, and residual stromal bed calculation in refractive screening. This is the capability that distinguishes the model from a conventional A/B scanner.

Configuration Chosen to the Caseload

Published material describes availability as B alone, A and B, or full A, B and P, so a service specifies what it will actually use rather than paying for unused modalities. Adding a modality later usually means buying a second instrument. Medigear.uk confirms which configurations remain available and their pricing.

Three and a Half Kilograms with a 12.1 Inch Screen

At 3.6 kg, the unit moves easily between rooms or to a satellite clinic, while a 12.1-inch touchscreen remains large enough for diagnostic review. Lightweight instruments often compromise on screen size, and this combination avoids that trade.

Built-In Computer with No Host PC

The workstation is integrated behind the touchscreen, so there is no computer to specify, maintain or replace, and nothing to configure on arrival. That removes a compatibility question and an ageing PC from the upgrade cycle.

Multi-Gain Review From a Single Freeze

Where the post-gain function is fitted, a frozen acquisition can be reviewed across many gain settings without rescanning. That shortens examination time and reduces repeat probe contact, which matters with anxious or paediatric patients. Medigear.uk confirms whether the function is present in the supplied build.

Specification Build Confirmed Before Order

Two specification sets circulate for this model, differing on A-scan range and accuracy, gain, playback, eye modes and IOL method count. Those are exactly the figures a surgical service needs to be certain about. Medigear.uk obtains them for the specific build being quoted, rather than publishing a single set and hoping it matches.

Manufacturer Attribution Established

Listings credit this model to two different companies, and one of them publicly offers OEM services. Warranty, service routing and probe supply all follow the producing entity rather than the badge on the front. Medigear.uk establishes who builds the unit and who carries the warranty before supply.

Three Modalities: A-Scan, B-Scan and Pachymetry

The full configuration provides biometry, posterior segment imaging, and corneal thickness measurement in a single instrument. Configuration availability is confirmed with Medigear.uk before ordering.

Pachymeter: 20 MHz Across 0.3 to 1.5 mm

Corneal pachymetry operates at 20 MHz over a 0.3-1.5 mm measurement range, with an accuracy of ≤0.01 mm. That range comfortably covers both normal and pathological corneal thicknesses.

Configuration Options

Published material describes availability as B alone, A and B combined, or full A, B and P. Which configurations remain available, and their pricing is confirmed in the quotation.

12.1 Inch Touchscreen with Built-In Computer

The workstation runs on an integrated computer behind a 12.1-inch touchscreen, eliminating the need for a host PC. Screen size is generous relative to the unit's weight.

Weight: 3.6 kg

The complete instrument weighs 3.6 kg, light enough to carry between rooms or to a satellite clinic without difficulty.

B-Scan Frequency: 10 MHz

B-scan operates at 10 MHz, consistent across published sources for this model.

B-Scan Depth: 60 mm or Greater

Depth is stated as 60 mm or greater, covering the axial length of the eye with margin for orbital structures.

Scanning Angle: 53 Degrees

The exploration angle is 53 degrees, defining the field captured in a single sector sweep.

B-Scan Resolution

Axial resolution is 0.2 mm and lateral resolution 0.4 mm, consistent across published sources.

Grey Scale: 256 Levels

Images are rendered across 256 grey levels, with picture processing covering brightness, contrast, pseudo-colour, measurement, and image annotation.

Adjustable Gain Range

Sources list the gain range as either 0-99 dB or 20-105 dB, depending on the build. Medigear.uk confirms the figure for the unit being supplied.

Image Freezing and Playback

Image freezing is specified at 20 acquisitions, with playback given as either 60 or 150 frames, depending on the source. Both are confirmed for the build supplied.

A-Scan Measurement Range and Accuracy

Sources give the measurement range as 0 to 40 mm or 0 to 60 mm, and accuracy as ≤0.04 mm or ≤0.05 mm. These are the figures a cataract service must confirm, and Medigear.uk obtains them in writing.

Eye Modes and Custom Modes

Sources give either six default modes with three customisable, or seven with two. Mode selection directly affects measurement accuracy, so the actual provision is confirmed before the order.

IOL Calculation Methods

Sources provide either six or eight methods, with comparisons across formulae and standard deviation calculations. Formula availability determines which eyes can be planned, and the exact set is confirmed in writing.

Probe Drive Type

Sources describe either mechanical sector scanning or a closed-loop, magnetically driven probe with position sensing, the latter intended to reduce mechanical wear. Drive type affects probe service life andhas beens confirmed for the supplie buildd.

Certification and Manufacturer Attribution

Listings reference CE and FDA, with EEC and ISO 13485 on some, and credit the model to two different companies. Medigear.uk obtains documentary evidence for each certification and identifies the producing entity and warranty holder prior to supply.

The Visionstar SK-3000 Ophthalmic Scanner brings A-scan biometry, B-scan imaging, and corneal pachymetry into one 3.6 kg instrument with a 12.1-inch12.1-inch touchscreen and built-in computer, with pachymetry at 20 MHz across 0.3 to 1.5 mm, for opening-angle glaucoma assessment and refractive screening applications that biometry and imaging alone do not reach. That suits ophthalmology clinics covering posterior segment assessment, cataract and IOL planning services, and practices that screen for glaucoma or perform refractive surgery. Because two specification sets circulate for this model and listings credit two different producing companies, the A-scan range and accuracy, gain, playback, eye modes, IOL method count, probe drive type, manufacturer attribution and certification evidence are all confirmed in writing for the specific build being quoted before supply.
