LINK LCP-200

Five notations, and it works behind a mirror

The LINK LCP-200 is a LogMAR chart display on a compact 17 inch XGA panel weighing 2kg. It records acuity in five notations, randomises optotypes to prevent memorisation, and supports a path folding mirror for rooms without a direct sight line.

Rooms Requiring a Folding Mirror

Where a consulting room cannot offer the optical distance along a single sight line, a path folding mirror is the conventional solution, and it requires the chart to be displayed mirrored. Providing that as a function rather than an afterthought means the display works properly in the reversed arrangement instead of needing a workaround. For practices already committed to a mirror layout, this is the specification that determines whether a given screen can be used at all.

Clinical and Research Settings Using LogMAR

LogMAR is the scale used in clinical trials and increasingly in hospital ophthalmology, because its equal step sizes make it suited to statistical comparison in a way decimal and Snellen notations are not. A display carrying LogMAR alongside four other notations lets a practice record in whatever convention a referral, an audit or a study requires, without anyone converting figures by hand and introducing arithmetic error.

Repeat Testing and Screening Programmes

Randomised optotype display addresses a genuine problem in repeat testing. Patients seen frequently, children reading with one eye then the other, and anyone motivated to perform well can all memorise a fixed chart. Randomising the presentation means each reading measures vision rather than recall, which matters most in occupational screening and wherever a result carries consequences for the person sitting the examination.

Colour Vision and Binocular Assessment

Ishihara colour vision testing, traffic light presentation, Worth, Schober, coincidence and stereo tests sit alongside the acuity charts. Colour vision work in particular is often handled with separate printed plates, and having it within the same display keeps the examination continuous while ensuring the presentation conditions stay consistent between one patient and the next.

Notation Flexibility Without Conversion

Recording acuity in five notations sounds like a convenience and is closer to a safeguard. Converting between Snellen, decimal and LogMAR by hand is exactly the sort of routine arithmetic that produces occasional errors, and an error in a recorded acuity can follow a patient through a referral. Selecting the notation directly removes that step from the process entirely. Removing a manual step removes a class of error. Recording in the required scale directly is simply safer.

Measuring Vision Rather Than Memory

A patient who has learned the chart produces a reading that overstates their vision, and nothing about the result reveals it. Randomised presentation closes that gap. In occupational screening, licence-related testing and any situation where the patient has reason to perform well, the difference between measuring sight and measuring recall is the whole purpose of the examination. A reading that overstates vision serves nobody well.

Clinical Breadth in a Small Panel

Two kilograms and a 420mm by 350mm footprint carrying colour vision, stereo, contrast sensitivity, Schober and coincidence testing is an unusual combination. Smaller clinics, domiciliary rooms and premises with limited wall space are not obliged to trade away test breadth to fit the equipment they can physically accommodate. Physical fit decides more purchases than specifications alone do. Capability and footprint rarely sit together this comfortably.

Five Acuity Notations Including LogMAR

Five grade, decimal, LogMAR, Snellen in feet and Snellen in metres are all available. LogMAR is the scale used in clinical research, so results transfer without conversion.

Mirror Image Function

A mirror image mode allows the panel to be used with a path folding mirror, giving the optical distance a short room cannot provide directly along a single sight line.

Randomised Optotype Display

Optotypes can be presented at random. A patient returning for a repeat test, or reading with one eye after the other, cannot rely on having memorised the previous sequence.

Broad Clinical Test Library

Schober, Worth, cross grid, coincidence, ETDRS, stereo, astigmatism, traffic light, contrast sensitivity, fixation point and Ishihara colour vision tests are all carried.

Six Mask Types

Background change, single, horizontal, vertical, red green and contrast sensitivity masking let the practitioner isolate precisely the part of the chart a patient should be reading.

Dual Unit Distance Setting

Distance sets from 2 to 7 metres in 0.1 metre steps or 6 to 24 feet in half foot steps, so the display matches whichever measurement the practice works in.

Adjustable Contrast and Real Time Red Green

Contrast adjusts for both optotypes and the ETDRS chart, and the red and green fields adjust in real time during testing rather than requiring a return to a settings menu.

Compact and Low Power

At 420mm by 350mm by 40mm, 2kg and a maximum of 20 watts, the panel fits and mounts where larger displays cannot, and adds little to the running load of the room.

The LINK LCP-200 LogMAR chart display packs a broad clinical test library into a 17 inch XGA panel weighing 2kg. Acuity records in five notations covering five grade, decimal, LogMAR and Snellen in both feet and metres, with distance settable from 2 to 7 metres in 0.1 metre steps or 6 to 24 feet in half foot steps. A mirror image function supports use with a path folding mirror where a room cannot provide the sight line directly.

The test library covers Schober, Worth, cross grid, coincidence, ETDRS, stereo, astigmatism, traffic light, contrast sensitivity, fixation point and Ishihara colour vision tests, alongside cross cylinder, red green panel and red green balance. Six mask types isolate the chart, optotypes display at random to prevent memorisation, contrast adjusts for optotypes and ETDRS, and red and green adjust in real time. The panel measures 420mm by 350mm by 40mm, draws a maximum of 20 watts and offers video and audio display.

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

Five: a five grade scale, decimal, LogMAR, Snellen in feet and Snellen in metres. LogMAR matters because it is the scale used in clinical research and hospital practice, so a result can be recorded in the convention a referral needs without anyone converting it by hand. Equal step sizes are what make the logarithmic scale suited to comparison.

It displays the chart reversed so the panel can be used with a path folding mirror. Where a consulting room cannot provide the optical distance along a direct sight line, a mirror is the usual answer, and the display has to present a mirrored image for that arrangement to work correctly. Without it the chart would read backwards in that arrangement.

Because a patient who has memorised the chart produces a reading that overstates their vision, and the result gives no sign of it. Randomising the presentation means each reading reflects what the patient can actually see. This matters most in repeat testing and occupational screening.

From 2 to 7 metres in 0.1 metre steps, or 6 to 24 feet in half foot steps. Offering both measurement systems means the display matches whichever the practice works in, and the fine increments allow the setting to reflect the actual room, not some rounded approximation. Distance accuracy feeds straight into optotype sizing.

Schober, Worth, cross grid, coincidence, ETDRS, stereo, astigmatism, traffic light, contrast sensitivity, fixation point and Ishihara colour vision tests, alongside cross cylinder, a red green panel and red green balance. Optotypes cover E, C, letters, numbers and children's targets. That breadth covers most of a thorough examination on one panel.

Six: background change, single, horizontal, vertical, red green and contrast sensitivity masking. Masking isolates the part of the chart a patient should be reading, which helps those who lose their place and those affected by crowding near their threshold. Crowding is a genuine optical effect near threshold.

Yes, for both the optotypes and the ETDRS chart, and the red and green fields adjust in real time during testing. Being able to alter these without leaving the test keeps the examination flowing and lets the practitioner respond to what the patient is reporting.

The vision chart measures 420mm by 350mm by 40mm and weighs 2kg, with a maximum consumption of 20 watts. Those figures make it the most compact display of this type in the range and simple to mount where a larger panel would not fit comfortably. Low consumption also keeps the heat load in a small room modest.
