LINK VT-350

Near Point and Presbyopic Testing

Automatic convergence and pupillary distance adjustment during near testing means the eyes are correctly converged and the lenses correctly centred for close work without the practitioner setting either by hand. Near addition is determined in the geometry the patient will actually use, and the illuminated near point card with its various charts removes the dependence on consulting room lighting that otherwise makes near acuity results difficult to compare between visits.

Precise Vergence and Phoria Investigation

Prism resolution of 0.1 prism dioptres is a substantial step beyond what geared heads offer. Where fusional reserves are being measured or a small vertical deviation is suspected, the difference between one prism dioptre and the next is exactly the territory in which the answer sits. Being able to work at a tenth of that interval turns an approximate finding into a measurement worth recording.

High Astigmatism in Either Notation

Cylinder from minus 8.75D to plus 8.75D covers substantial astigmatic corrections without auxiliary lenses, and accommodates both plus and minus cylinder recording conventions directly. Practices working to a particular convention, or receiving prescriptions written in the other, can proceed without converting figures by hand and introducing the arithmetic errors that conversion invites. Working directly in the practice convention saves a conversion step each time.

Infection Control in Busy Clinics

The face shield and forehead rest both detach, which makes cleaning the surfaces that contact a patient's face genuinely practical rather than a wipe around a fixed component. For clinics running back to back appointments, a hygiene routine that can be completed quickly between patients is one that actually gets completed, and removable parts are what make that realistic.

A Step That Cannot Be Skipped

Setting convergence and centration for near work is easy to rush when an appointment is running late, and the consequence is a near addition determined in the wrong geometry. Handing that adjustment to the instrument means it happens identically for every patient regardless of how the day is going. Automation earns its value on the busy afternoons, not the quiet mornings. Consistency across patients is the point. Every patient receives the same near geometry.

Resolution That Changes What Is Measurable

A tenth of a prism dioptre and a single degree of axis are not marginal improvements over a geared head, they change which findings can be recorded as measurements rather than impressions. Small vertical deviations and fine axis determinations both sit in that territory, and both are clinically significant precisely because they are easy to miss with coarser equipment. Equipment sets the floor on what can be found.

Cleaning That Fits Between Appointments

Detachable face shield and forehead rest turn between-patient cleaning from an awkward job around fixed components into a straightforward one. Hygiene expectations in clinical settings have risen considerably, and equipment designed so the contact surfaces come away makes meeting those expectations a matter of routine rather than of effort. A routine that is quick is a routine that survives a full clinic list.

Automatic Convergence and Centration

Convergence and pupillary distance are adjusted by the instrument during near point testing, removing a manual step and ensuring near geometry is set correctly every time rather than when remembered.

Prism to a Tenth of a Dioptre

Rotary prism covers 0 to 20 prism dioptres at 0.1 or 0.5 prism dioptre resolution. Small vergence differences become measurable rather than falling between the available steps.

Independent Left and Right Adjustment

Pupillary distance adjusts independently for each side. Monocular centration is rarely perfectly symmetrical, and setting each eye separately reflects the patient as they actually are.

Separate Distance and Near Ranges

Pupillary distance is specified as two ranges, 52mm to 80mm for distance and 48mm to 76mm for near, in 0.5mm or 1mm steps, matching the convergence that occurs during close work.

Four Spherical Step Sizes

Sphere is selectable in 0.25D, 0.50D, 1.00D and 3.00D steps. Large changes happen in one movement while fine refinement stays available, without stepping through every intermediate value.

Wide Cylinder in Both Notations

Cylinder covers minus 8.75D to plus 8.75D in 0.25D steps, so plus and minus cylinder conventions are both accommodated across a range wider than manual heads typically manage.

Removable Face Shield and Forehead Rest

Both the face shield and the forehead rest detach for cleaning. Between-patient hygiene on surfaces that touch the face is far easier when the components come away entirely.

Illuminated Near Point Card

A near point card carrying various charts is fitted, with built-in white LED lighting so near testing does not depend on the ambient light level in the consulting room.

The LINK VT-350 digital phoropter automates the parts of subjective refraction that manual heads leave to the practitioner. Convergence and pupillary distance adjust themselves during near point testing, so near geometry is correct for every patient rather than when there is time to set it. Spherical power runs from minus 19.00 to plus 16.75D in 0.25D, 0.50D, 1.00D and 3.00D steps, cylinder covers minus 8.75D to plus 8.75D accommodating both notations, and axis steps at 1 or 5 degrees.

Rotary prism resolves to 0.1 prism dioptres, retinoscope lenses of plus 1.50D and plus 2.00D are provided, and the auxiliary complement covers pinhole, Maddox rods, red and green lenses, polarising filters and fixed prisms. Pupillary distance is handled as separate distance and near ranges with independent left and right adjustment, the face shield and forehead rest detach for cleaning, and a near point card carries its own white LED lighting. The head is 381mm by 286mm by 111mm at 3.8kg with a separate control panel.
