Visionstar SAB-200

Cataract and IOL planning services use the A-scan side, which operates at 10 MHz to a depth of 40 mm and measures anterior chamber depth, lens thickness, and vitreous body length across phakic, aphakic, dense, and various IOL eye modes. Six formulae are listed,, including SRK-II, SRK-T, Hoffer-Q, Hollada,y and Binkhorst-II, a range that tracks axial length across short, averag,e and long eyes. Medigear.uk confirms the complete formula set and adjustable constants in writing before any procurement decision, since those determine whether the system fits an existing surgical protocol.

Ophthalmology clinics use B-scan where the fundus cannot be viewed directly. The manufacturer stathat tes the system is used the for diagnosis of intraocular diseaincludingming vitreous opacity, retinal detach,ment and ocular fundus tumours, with normal, vitreous body enhance,ment and retina observation modes provided. Those are the manufacturer's stated applications, and all interpretation remains with the practitioner. Detailed B-scan parameters are obtained from the manufacturer rather than assumed from related models.

Services with established IT arrangements may prefer a PC-based system, since data sits on practice hardware under practice access control and backup rather than on an instrument. That is genuinely an advantage where policies and systems already exist. It becomes a liability where the software requires an operating system the organisation cannot support, which is why Medigear.uk settles the platform question first.

Practices weighing entry cost against integrated hardware should note that a PC-based system defers the display and computer cost rather than removing it. MedigearUKk provides the computer requirements sothat the  total cost can be assessed properly.

Six IOL Formulae Across the Axial Length Range

Formula selection tracks axial length, and a system listing SRK-II, SRK-T, Hoffer-Q, Holladay and Binkhorst-II among six covers short, average and long eyes without exporting measurements to a separate calculator. Medigear.uk confirms the complete set and any adjustable constants in writing, since the published list is truncated in some sources.

Runs on a Computer You Already Own

The workstation software runs on practice hardware rather than requiring a dedicated console, which defers the display and processing cost and lets the computer be replaced on its own cycle. For a practice with a standard hardware refresh, that separation is useful. Medigear.uk obtains the stated computer requirements so suitability can be checked first.

Screen Size and Position Are Yours to Choose

An integrated console fixes the display at the manufacturer-specified size and angle. A PC-based system leaves that to the practice, which matters where a room layout or a clinician's preference calls for a larger screen or a particular mounting position.

Data Sits Under Your Own IT Governance

Patient data resides on practice hardware under existing access control, backup, and retention arrangements, rather than on an instrument with its own storage, for an organisation with established information governance, which is simpler than managing a separate device. Medigear.uk confirms the software's storage and export behaviour before order.

Lower Entry Cost Than an Integrated Console

Removing the display and computer from the instrument reduces the purchase price, though it defers rather than removes that cost. Whether the saving is real depends on whether suitable hardware already exists. Medigear.uk provides the computer requirements so total cost can be assessed rather than estimated.

Software Platform Established Before Purchase

Published material lists the supported platform as Windows versions that had reached the end of support between 2014 and 2020. Whether that reflects current software or an unrevised listing determines whether the system can be placed on a clinical network at all. Medigear.uk puts the question to the manufacturer and obtains the answer in writing before any order.

Certification Claims Verified Documentarily

Listings for this model reference CE, FDA and ISO 13485, a broader claim than appears on comparable products. Because each represents a different regulatory or quality route, Medigear.uk obtains documentary evidence for each rather than accepting a listing, and confirms the applicable marking and registration position for supply.

B-Scan Parameters Confirmed Rather Than Assumed

Detailed B-scan figures are not available for this model, and related products in the same range are not reliable substitutes. Medigear.uk obtains depth, frequency, resolution, scanning angle, gain, and grey scale directly from the manufacturer so that a buyer can compare against real figures rather than inferred ones.

PC-Based Architecture

An interface unit connects the probes to a practice-supplied Windows computer, with software providing the image workstation. Display, processing and storage all sit on the practice machine rather than in the instrument.

Supported Operating Systems

Published material lists Windows XP, Vista and Windows 7, all past end of support. Medigear.uk obtains the currently supported versions from the manufacturer in writing before order, since this determines network suitability.

Separate Interface Unit

A separate unit links the probes to the computer. Its dimensions, weight, connection type, and power requirements are not published and must be obtained in writing.

Six IOL Formulae

Six formulae are listed, including SRK-II, SRK-T, Hoffer-Q, Holladay and Binkhorst-II. The complete set and any adjustable constants are confirmed with the manufacturer.

A-Scan Depth: 40 mm at 10 MHz

A-scan operates at 10 MHz with LED indication to a depth of 40 mm. Measurement precision and averaging behaviour are confirmed, since both determine suitability for surgical planning.

A-Scan Biometry Measurements

Measurements cover anterior chamber depth, lens thickness and vitreous body length. These are the inputs to the IOL formulae, and the inclusion of axial length totalling and averaging is confirmed.

Four Eye Modes

Phakic, aphakic, dense, and various IOL modes allow the system to be set to the presentation rather than applying a single velocity assumption, which directly affects measurement accuracy.

Normal, Vitreous Enhancement and Retina Observation Modes

B-scan provides normal, vitreous body enhancement and retina observation modes, targeting structures of differing reflectivity within the posterior segment.

B-Scan Detailed Specification

Depth, frequency, resolution, scanning angle, gain range and grey scale are not published for this model. Medigear.uk obtains each from the manufacturer rather than assuming figures from related products.

Probe Configuration

Which probes are supplied as standard, whether alternative frequencies are available and how they connect to the interface unit are confirmed with the manufacturer before order.

Computer Requirements

Processor, memory, connection type and operating system determine whether existing practice hardware is suitable. A system that will not run on machines already owned carries an unquoted cost. Requirements are obtained in writing.

Data Storage and Backup

Patient data resides on the practice computer under existing IT arrangements. How the software stores, exports and backs up records is confirmed before order.

Report Output

Report generation and export formats determine how findings are captured in a patient record. Available formats and any template control are confirmed with the manufacturer.

Software Update and Support Arrangements

A PC-based system depends on software support throughout its life, particularly when the operating system changes. Update provision and support terms are established at quotation.

Certification Position

Listings reference CE, FDA and ISO 13485. Each is verified documentarily, and the applicable marking and registration position for supply is confirmed in writing.

Manufacturer Provenance

The system is listed by Chongqing Vision Star Optical Co., Ltd. Because models in this category appear under several brand names, Medigear UK identifies which entity carries the warranty and where service is routed.

Documentation Pack Supplied at Order

Every unit is accompanied by the manufacturer's technical documentation, installation guidance, software documentation, and applicable certification records. Medigear.uk assembles this at order rather than leaving buyers to source it, with confirmed values supplied in writing where a parameter was previously unpublished.

The Visionstar SAB-200 Ophthalmic Scanner provides A-scan biometry and B-scan imaging through an interface unit and workstation software running on a practice-supplied Windows computer, with 40 mm A-scan depth at 10 MHz, four eye modes and six listed IOL formulae covering SRK-II, SRK-T, Hoffer-Q, Holladay and Binkhorst-II among them. That architecture suits cataract and IOL planning services, ophthalmology clinics assessing the posterior segment, and practices with established IT arrangements that prefer data on their own hardware. Because published material lists operating platforms that have reached end of support, the currently supported operating systems are established in writing before any order, alongside documentary verification of the CE, FDA, and ISO 13485 claims, the detailed B-scan parameters, computer requirements, and software support terms.
