Visionstar Retiwave-1000

A-Scan Biometry With Lens Calculation

The axial examination reports anterior chamber depth, lens thickness and axial length among other parameters, and calculates intraocular lens power from the axial length.

B-Scan Cross-Sectional Imaging

B-mode produces a profile image of the eyeball showing internal anatomy, which is what allows assessment to continue when the media are too opaque for light to pass.

Both Examinations on One Console

Biometry and cross-sectional imaging run from the same instrument, so a department needing both does not require two separate systems or two positions. Staff also learn one interface rather than two separate ones.

Adjustable Frozen Images

Parameters can be adjusted on images already frozen and stored, so a review afterwards is not limited to the settings chosen at the moment of acquisition.

Gain and Time Gain Compensation

Both controls govern how the returning signal is displayed, letting the operator bring out structures that would otherwise be lost in the presentation.

Caliper, Marker and Area Tools

Measurement tools work on stored images, supporting careful assessment of structures and annotation of findings for later review or discussion.

Patient and Physician Records

Each examination is stored with patient and physician details attached, and output to electronic record systems keeps images with the rest of a patient's file.

Transport Case Supplied

An aluminium case is shown with the system, suiting departments that move the console between sites or store it securely between clinics. A keyboard and mouse accompany the console for record entry.

Assessment Behind Opaque Media

This is the central use. A dense cataract, vitreous haemorrhage or corneal opacity prevents any examination that depends on light reaching the retina, and in those eyes an ophthalmoscope shows nothing useful. Ultrasound passes through regardless, so B-mode imaging allows the posterior segment to be assessed when direct viewing has become impossible. Findings inform the clinician's judgement rather than replacing it. Ultrasound therefore fills a gap that optical methods cannot reach.

Cataract Surgery Planning

The A-scan supports the measurement side of the same consultation, reporting anterior chamber depth, lens thickness and axial length and calculating lens power from the axial figure. Having imaging available alongside means that where a dense cataract prevents a view of the retina, the posterior segment can still be examined before surgery is planned. Both examinations therefore happen within a single appointment. Planning proceeds with a fuller account of the eye involved.

Ocular Trauma and Emergency Assessment

Injured eyes frequently cannot be examined conventionally, whether through haemorrhage, media disruption or the practical limits of examining a distressed patient. Cross-sectional imaging gives an account of internal structure in those circumstances. The manufacturer lists ocular trauma among the examinations for which the system is used. Urgency in such cases makes an immediately available examination valuable.

Vitreoretinal and Macular Examination

Vitreous body disease, detachment of the retina or choroid and macular disease are all listed among the contexts in which the system is applied. Caliper and area tools support measurement on stored images, and saved examinations allow appearances to be compared across visits as a condition is followed. Serial comparison depends on studies being retained and retrievable.

Examination Where Light Fails

The value of ocular ultrasound is straightforward: it works when nothing else does. Optical examination stops at the first opaque surface, and precisely the eyes that most need assessment are often the ones that cannot be viewed. B-mode imaging removes that limitation, giving a clinician information about the posterior segment that would otherwise be unavailable until surgery opened the eye. That information can change what a surgeon plans before operating. Knowing what lies behind a dense lens beforehand is genuinely valuable.

Measurement and Imaging Together

Combining A-scan biometry with B-scan imaging in one console means a single consultation can produce both the measurements cataract surgery requires and a view of the structures behind the lens. Departments equipping a service avoid buying and housing two instruments, and staff learn one interface rather than two. One console also means one maintenance arrangement to manage.

Review That Is Not Fixed at Acquisition

Because frozen images accept parameter adjustment afterwards, a study can be re-examined without recalling the patient. Caliper, marker and area tools working on stored images support that later review, and records held with patient and physician details keep each study attached to the person it belongs to. Retained studies also support discussion with colleagues afterwards. Nothing is lost because a setting was wrong at the time.

The Retiwave-1000 answers a limitation every optical examination shares: it cannot see past an opaque surface. By combining A-scan biometry with B-scan cross-sectional imaging in one digital console, it gives a clinician both the measurements cataract surgery requires and a view of the structures behind a lens that light cannot penetrate.

The A-scan reports anterior chamber depth, lens thickness and axial length among other parameters and calculates intraocular lens power. The B-scan produces a profile image of the eyeball showing internal anatomy, and the manufacturer lists cataract, vitreous body disease, ocular trauma, retinal or choroidal detachment, macular disease and intraocular tumour among the examinations for which it is used. Interpretation of those images remains a matter for the examining clinician.

Software supports the work around the images. Frozen studies accept parameter adjustment afterwards, gain and time gain compensation govern presentation, caliper, marker and area tools measure on stored images, and patient and physician records accompany each examination with output to electronic record systems.
