Visionix VX 110

Optometry practices use the VX 110 to collect objective refraction, keratometry, and corneal maps during a seated pre-examination. Automatic alignment and right-to-left positioning support acquisition by trained staff. The optometrist can then examine focusing power alongside surface shape, with both types of information available from the same measurement platform. Its photopic and mesopic outputs give the consultation a defined basis for discussing vision in bright and dim conditions.

Specialist contact lens services use the topographic maps and keratometry readings when assessing rigid lenses and orthokeratology. Corneal astigmatism and average keratometry describe the measured surface, while aberration analysis adds information relevant to multifocal lens assessment. Stored examinations support review of the eye's measured response during follow-up. The screen brings these outputs together for the practitioner who is evaluating lens fit and optical performance.

In corneal clinics, the keratoconus probability index and mapped surface patterns support assessment of irregular corneal shape. Repeated examinations supply records for monitoring, with corneal aberrometry describing associated optical effects. The instrument's connected outputs let the clinician examine the distribution of surface changes and the accompanying refractive measurements within an organised record.

Ophthalmology services assessing cataract can use retroillumination to inspect crystalline-lens opacities and the LOCS II or LOCS III scales to describe them. Wavefront and corneal analysis add optical context to the visible findings. The combination suits appointments where the clinician is considering focusing measurements, corneal irregularity, and lens appearance together. Local printing and manufacturer-described network review support the movement of examination results from the acquisition position to the interpreting professional.

Refraction and corneal mapping within one examination

The patient remains at the same instrument for objective refraction, keratometry, and Placido topography. This arrangement connects measurements that answer different parts of the same optical question: the eye's focusing power and the shape of its front surface. Acquisition staff can build that examination record around one set of patient supports, with the touchscreen providing the control point for the selected tests.

Automatic alignment gives capture a defined sequence.

Horizontal, vertical, and depth alignment are managed by the instrument, together with right-eye and left-eye positioning. The operator supervises the seated patient and the acquisition process through the touchscreen. Bringing these movements into the measurement sequence gives staff a clear division between positioning the person, supervising capture,e and reviewing the resulting data. Full eye tracking supports the instrument's alignment workflow.

Lighting conditions remain part of the refractive picture.re

Photopic and mesopic refraction keep bright-light and dim-light measurements within the assessment. The associated pupil area gives those values an optical context. For a clinician investigating differing visual experiences during the day and at night, the instrument provides results linked to those conditions. Its wavefront displays also support discussion of how the measured focusing errors and higher-order aberrations affect optical quality.

Lens assessment combines surface shape with aberration data

Rigid and orthokeratology lens assessment draws on keratometry, corneal astigmatism and topographic maps. Multifocal lens work can also use the spherical-aberration information within the optical analysis. These outputs connect the measured corneal surface with the focusing behaviour being assessed. For specialist contact lens appointments, the instrument places those complementary findings in one record that can be revisited during follow-up.

Follow-up records retain the mapped corneal pattern.

A topographic examination records the distribution of measured corneal shape across the mapped area. Stored records make those patterns available during later visits, alongside the corresponding refractive findings. The keratoconus probability index and corneal aberrometry add structured information to the review. This is useful in corneal services where the clinician follows the course of an irregular surface across a series of examinations.

Optical results explain several aspects of visual quality.

Refraction values, aberration displays, visual-acuity simulations and the modulation transfer function describe related aspects of the measured optics. The clinician can examine focusing error, additional distortion,n and contrast transfer within the same assessment. Each display gives a distinct way to discuss an optical result. This supports explanations grounded in the examination record, including conversations about bright-light and dim-light visual needs.

Lens-opacity images sit alongside the refractive findings

Retroillumination supplies a view of crystalline-lens opacities, and the LOCS II and LOCS III scales support their description. The accompanying refraction and aberration results provide optical context for that appearance. Cataract assessment can therefore draw on visible lens findings and measured focusing behaviour collected within the same device. The instrument organises those elements for the ophthalmologist's review and clinical interpretation.

Results can move from acquisition to review

The integrated printer, export functions and manufacturer-described networking give the examination record several routes into review. A local print supports immediate discussion, while compatible network arrangements make stored findings available at another review position. Customised reports bring together the selected measurements, graphs and maps. The practical benefit is continuity between the point where the eye is measured and the point where the findings are interpreted.

Routine upkeep follows the surfaces being handled.

The chin rest, forehead support, Placido ring assembly, touchscreen, and exterior each have a defined cleaning role in day-to-day use. Alcohol-free disinfectant wipes are specified for the rings, while the patient supports are cleaned before each measurement. Printing paper and optional chin-rest sheets are replenishable consumables. This surface-specific approach gives the department a repeatable care routine around the instrument's optical and contact areas.

Shack-Hartmann wavefront measurement

A Shack-Hartmann sensor analyses the returning optical wavefront, which describes how light has passed through the eye's optical system. The VX 110 uses these measurements for objective refraction and ocular aberration analysis. Its technical configuration provides 1,300 measuring points. The resulting data support numerical refractive values and optical-quality displays, with the pupil area retained as part of the measurement context.

Spherical, cylindrical and axis ranges

Spherical power is measured from -20 to +20 D, where D denotes dioptres, the unit of optical power. Cylinder power spans 0 to +8 D, and the axis range is 0–180°. Together, these outputs describe the focusing and astigmatic components of objective refraction. The instrument presents them alongside corneal information so the clinician can relate the refractive result to the measured surface pattern.

Three-zone pupil analysis and rapid sensor capture

The specified wavefront measuring area extends from 2 to 7 mm and is organised into three zones. This gives the optical analysis a defined pupil area across which the measurements are assessed. Wavefront acquisition takes 0.2 seconds. The capture figure belongs to that measurement stage, while the full examination also contains positioning, alignment, the selected modalities and professional review of the results.

A 24-ring Placido topographer

The Placido assembly presents concentric rings whose reflection describes the front surface of the cornea. Its 24 rings provide 6,144 measuring points, with more than 100,000 points analysed to construct the topographic representation. These are distinct sampling and analysis figures within the system. The resulting maps give the clinician a spatial description of corneal shape alongside the instrument's keratometry readings.

Defined corneal coverage and topographic range

At a corneal power of 43 D, the covered diameter extends from 0.75 mm to more than 10 mm. The topographic measurement range is 37.5–56 D. Visionix specifies repeatability of 0.02 D for this topography output. Keeping the reference power, coverage,e and measurement range together identifies the conditions attached to the mapped corneal area.

Keratometry and average corneal power

Keratometry describes corneal curvature in terms used during refractive and contact lens assessment. The VX 110 presents keratometry readings, corneal astigmatism and average keratometry, also labelled AVG K. These numerical outputs complement the spatial maps. A lens practitioner can therefore examine an overall curvature value and the distribution of surface shape as parts of the same measured examination.

Axial, tangential, elevation and refractive maps

The topography software presents several map types for examining the anterior corneal surface. Axial and tangential maps describe curvature patterns, while elevation and refractive maps provide further representations of the measured shape. The different views help the practitioner inspect where a feature lies and how it is distributed. Eccentricity and meridian information add numerical detail to the mapped pattern.

Corneal and ocular aberration outputs

The platform provides corneal aberrometry and ocular wavefront analysis. Corneal outputs describe optical effects associated with the measured corneal surface, while ocular analysis represents the measured optical system of the eye. Lower-order and higher-order results give the clinician separate categories for examining focusing errors and additional distortions. Zernike coefficients provide a numerical description of the individual aberration components within the analysis.

Photopic and mesopic refraction

Bright-light and dim-light objective refraction are available within the instrument's examination functions. These photopic and mesopic measurements allow the record to reflect different lighting conditions and associated pupil behaviour. Day and night findings can be considered alongside the optical-quality outputs. The feature supports appointments where the reported visual experience varies with lighting, with the instrument contributing condition-linked objective measurements.

Keratoconus probability and serial review

A keratoconus probability index accompanies the corneal maps and supports identification of patterns associated with an irregular corneal surface. Corneal aberrometry provides related optical information. Successive stored examinations support monitoring by keeping measured findings available for review over time. The index, maps and optical outputs form part of the clinician's assessment of the eye and its recorded course.

Rigid, orthokeratology and multifocal lens tools

The contact lens functions bring together surface maps, keratometry, average keratometry and corneal astigmatism. These outputs support rigid lens and orthokeratology fitting assessment. Spherical-aberration information adds an optical parameter relevant to multifocal contact lenses. The practitioner can examine the surface and optical findings in context, with recorded examinations available to document changes associated with ongoing lens wear.

Retroillumination and opacity grading

Retroillumination provides images of the crystalline lens for inspection of visible opacities. The software supports the LOCS II and LOCS III grading scales, allowing those appearances to be described in a structured form. Refraction and aberration outputs remain part of the wider examination. This combines lens appearance with optical measurements for cataract assessment and subsequent review by the ophthalmologist.

Visual-acuity simulation and contrast-transfer analysis

The wavefront results feed visual-acuity simulations and a modulation transfer function curve. Visual-acuity simulations illustrate image effects associated with the measured optical distortions. The curve describes the transfer of contrast across different levels of detail. Together, these displays offer ways to interpret the same optical findings and to discuss the relationship between focusing, aberrations and the quality of the resulting image.

Automatic positioning and patient supports

XYZ alignment controls the horizontal, vertical, al and depth relationship between the measuring head and the eye. Automatic right-eye and left-eye positioning supports the examination sequence, and the platform provides full eye tracking. The chin rest and forehead support locate the patient's head during capture. A 14 mm observation area gives the operator a defined field for viewing the eye within the measurement interface.

Integrated touchscreen and local printing

The 10.1-inch TFT touchscreen combines acquisition controls and result presentation in a 1024 × 600-pixel display. Multi-touch input supports interaction with the examination interface. An integrated monochrome printer provides local output from the instrument. External colour printing is available as an option, giving reports a further presentation format within compatible printing arrangements.

Communications and examination data

RS232, USB, VGA and LAN connections support the instrument's communication, display and data functions. Visionix describes networking with compatible patient-management software, customised reports and offline or web service review. Examination measurements, graphs and maps can be retained and shared through the supported arrangements. These capabilities connect the acquisition position with subsequent review while keeping the recorded outputs associated with the examination.

Mains supply and surface-specific care

The instrument operates from 100–240 V AC at 50–60 Hz and has a 300 W power rating. Its patient supports receive cleaning before each measurement, and the Placido rings use alcohol-free disinfectant wipes between patients. The screen and exterior receive regular cleaning. Optional chin-rest sheets, reference 4100-0014-00, and replenishable printer paper support the instrument's ongoing examination and reporting routine.

The VX 110 suits optometry and ophthalmology services that organise appointments around objective refraction, corneal shape, and specialist contact lens assessment. Its practical value lies in connecting acquisition and interpretation: automatic alignment collects the optical measurements, and the associated maps and reports keep them available for professional review. Day and night refraction provides a further reason to choose this configuration when lighting-related visual needs form part of the consultation.

For departments managing repeated examinations, the relevant ongoing work is surface-specific cleaning, paper replenishment and handling stored results. The platform fits a seated examination workflow in which the clinician wants refractive values, mapped surface detail, and lens-opacity images within one instrument. Its optical assessment combines Shack-Hartmann wavefront sensing with a 24-ring Placido topographer.
